Mendeliome v1.2295 | ARHGEF40 |
Chirag Patel gene: ARHGEF40 was added gene: ARHGEF40 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: ARHGEF40 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: ARHGEF40 were set to PMID: 39838643 Phenotypes for gene: ARHGEF40 were set to Neurodevelopmental disorder MONDO:0700092 Review for gene: ARHGEF40 was set to RED Added comment: 2 individuals with global developmental delay, hypotonia, short stature, hearing impairment, nystagmus, feeding issues, and dysmorphism (bifid uvula, narrow mouth, high palate, micrognathia). Trio clinical whole exome sequencing identified de novo variants in the ARHGEF40 gene at position p.Arg225, which is fully conserved in mammals and located within the n-terminal keratin binding region (p.Arg225Trp and p.Arg225Gln). Of note, multiple additional probands with rare missense variants at the p.Arg225 residue have been identified by the same laboratory (but there was no consent for publication, providing further evidence of the importance of this residue. The ARHGEF40 gene (aka SOLO) is a member of the Rho guanine nucleotide exchange factor (Rho-GEF) family of proteins, which stimulate Rho signal transduction molecules by converting them from inactive GDP-bound form to the active GTP-bound state. No functional studies to characterise disease-gene relationship or disease mechanism. Sources: Literature |

Mendeliome v1.2293 | HECTD1 |
Chirag Patel gene: HECTD1 was added gene: HECTD1 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: HECTD1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: HECTD1 were set to PMID: 39879987 Phenotypes for gene: HECTD1 were set to Neurodevelopmental disorder MONDO:0700092 Review for gene: HECTD1 was set to GREEN Added comment: 14 unrelated individuals (identified through GeneMatcher) with 15 variants of uncertain significance (VUS) in HECTD1 (10 missense, 3 frameshift, 1 nonsense, and 1 splicing variant). Of the 15 different variants in HECTD1, 10 occurred de novo, 3 had unknown inheritance, and 2 were compound heterozygous. All variants were absent in gnomAD, and HECTD1 is highly intolerant to loss-of-function variation (loss-of-function-intolerant score of 1). Clinical presentation was variable developmental delay, intellectual disability, autism spectrum disorder, ADHD, and epilepsy. The one individual with compound heterozygous variants had growth impairment along with NDD. The variants were inherited from apparently healthy parents, suggesting that genetic or environmental modifiers may be required to develop the phenotype. Significant enrichment of de novo variants in HECTD1 was also shown in an independent cohort of 53,305 published trios with NDDs or congenital heart disease. HECT-domain-containing protein 1 (HECTD1) mediates developmental pathways, including cell signalling, gene expression, and embryogenesis. Conditional knockout of Hectd1 in the neural lineage in mice resulted in microcephaly, severe hippocampal malformations, and complete agenesis of the corpus callosum, supporting a role for Hectd1 in embryonic brain development. Functional studies of 2 missense variants and 1 nonsense variant in C. elegans revealed dominant effects, including either change-of-function or loss-of-function/haploinsufficient mechanisms.

Five unrelated individuals reported with bi-allelic variants in DAP3 and variable clinical presentations ranging from Perrault syndrome (sensorineural hearing loss and ovarian insufficiency) to an early childhood neurometabolic phenotype. Assessment of respiratory-chain function and proteomic profiling of fibroblasts from affected individuals demonstrated reduced MRPS29 protein amounts and, consequently, decreased levels of additional protein components of the mitoribosomal small subunit, as well as an associated combined deficiency of complexes I and IV. Lentiviral transduction of fibroblasts from affected individuals with wild-type DAP3 cDNA increased DAP3 mRNA expression and partially rescued protein levels of MRPS7, MRPS9, and complex I and IV subunits, demonstrating the pathogenicity of the DAP3 variants.

All individuals presented with spinal rigidity primarily affecting the cervical and dorsolumbar regions, scoliosis, and respiratory insufficiency. Creatine kinase levels were variably elevated. The clinical course worsened with intercurrent disease or certain drugs in some; one individual died from respiratory failure following infection. Muscle biopsies revealed irregularities in oxidative enzyme staining with occasional internal nuclei and rimmed vacuoles. HMGCS1 encodes a critical enzyme of the mevalonate pathway. Notably, biallelic hypomorphic variants in downstream enzymes including HMGCR and GGPS1 are associated with muscular dystrophy. Hmgcs1 mutant zebrafish displayed severe early defects, including immobility at 2 days and death by day 3 post-fertilisation and were rescued by HMGCS1 mRNA. Four variants tested (S447P, Q29L M70T, and C268S) have reduced function compared to wildtype HMGCS1 in zebrafish rescue assays Sources: Literature |

PMID: 39420202 - 12 CAKUT patients from 9/301 (3%) families carried 5 different rare heterozygous TSHZ3 missense variants. However, 1 of the variants (p.Ser58Gly) present in 5 of the families is more common in gnomAD v4.1 than you would expect for a dominant disease including 5 homozygotes (1,408/1,612,114 alleles, 5 hom, AF=0.0008734). The authors state this is not unexpected in a condition, such as CAKUT. However, the different missense variants are inherited from unaffected parents in at least 2/9 families (there was no phenotype information available for an additional 3 parents).

WES/WGS identified 25 LOF and 6 missense variants in MARK2 gene (Microtubule affinity-regulating kinase 2) which contributes to establishing neuronal polarity and developing dendritic spines. LOF variants were de novo (16/25), inherited (4/25), or unk (5/25). All 6 missense variants were de novo and clustered in the kinase or KA1 domains. The mRNA and protein expression of MARK2 in PBMCs were significantly lower in affected individuals with LOF variants than in the control group. In vitro expression assay of missense variants supported the effect of MARK2 loss. Proband-derived and CRISPR-engineered isogenic induced pluripotent stem cells (iPSCs) showed MARK2 loss leads to early neuronal developmental and functional deficits, including anomalous polarity and disorganization in neural rosettes, as well as imbalanced proliferation and differentiation in neural progenitor cells (NPCs). Mark2+/- mice showed abnormal cortical formation and partition and ASD-like behaviour. Through the use of RNA sequencing (RNA-seq) and lithium treatment, they linked MARK2 loss to downregulation of the WNT/β-catenin signaling pathway and identified lithium as a potential drug for treating MARK2-associated ASD.

Three unrelated children reported with a syndromic, early-onset neurodevelopmental disorder, each of whom had a de novo deletion in the CHASERR locus. The children had severe encephalopathy, shared facial dysmorphisms, cortical atrophy, and cerebral hypomyelination - a phenotype that is distinct from the phenotypes of patients with CHD2 haploinsufficiency. CHASERR deletion results in increased CHD2 protein abundance in patient-derived cell lines and increased expression of the CHD2 transcript in cis, indicating bidirectional dosage sensitivity in human disease.

Skeletal survey showed mild thoracolumbar scoliosis, four sacral segments, absent ossification of the inferior pubic rami, and patellar aplasia. Trio WGS identified compound heterozygous loss of function variants in BMP5 (c.88_89del, p.(Gly30Argfs*11) and c.1104+2del, p.(?). Abnormal splicing was proven on the suspected splice variant using maternal fibroblasts. BMP5 expression is confined to specific parts of the skeleton and cartilage in mice and is tightly regulated by different enhancers. Previous studies of chicken embryonic heart development showed BMP5 expression in the endoderm underlying the precardiac mesoderm, the myocardium of the atrioventricular canal and outflow tract regions.

Patient fibroblasts displayed abnormal cilia that are long and show abnormal transport. A homozygous Pskh1 mutant mouse faithfully recapitulated the human phenotype and displayed abnormally long cilia. The phenotype could be rationalized by the loss of catalytic activity observed for each recombinant PSKH1 variant using in vitro kinase assays. Human PSKH1 is a poorly understood gene that may play important role in intracellular trafficking, is sensitive to intracellular Ca2+ concentration, and is localized to centrosomes, suggesting a link to cystogenesis.

Clinical features included: muscle weakness/myopathy (9/9), motor incoordination/gait disturbance (8/8), delayed gross motor development (6/9), dysarthria (5/5), peripheral neuropathy (3/3 adults), bilateral sensorineural hearing impairment (6/9), decreased body weight (8/9), short stature (5/9), microcephaly (4/9), respiratory issues/insufficiency (6/9), cerebellar atrophy (4/9), pituitary hypoplasia (3/9). WES or WGS identified biallelic loss-of-function variants in RFC4 (3 frameshift, 2 splice site, 1 single AA duplication, 2 single AA deletions, 2 missense), and almost all are likely to disrupt the C-terminal domain indispensable for Replication factor C (RFC) complex formation. All variants segregated with the disease. The RFC complex (with 5 subunits) is central to process of regulation of DNA replication, and it loads proliferating cell nuclear antigen onto DNA to facilitate the recruitment of replication and repair proteins and enhance DNA polymerase processivity. RFC1 is associated with CANVAS but the contributions of RFC2-5 subunits on human Mendelian disorders is unknown. Analysis of a previously determined cryo-EM structure of RFC bound to proliferating cell nuclear antigen suggested that the variants disrupt interactions within RFC4 and/or destabilize the RFC complex. Cellular studies using RFC4-deficient HeLa cells and primary fibroblasts demonstrated decreased RFC4 protein, compromised stability of the other RFC complex subunits, and perturbed RFC complex formation. Additionally, functional studies of the RFC4 variants affirmed diminished RFC complex formation, and cell cycle studies suggested perturbation of DNA replication and cell cycle progression.

Notably one was the parent of a child with recessive SeSAME syndrome (established gene-disease association). Patch-clamp recordings in HEK293T cells revealed apparent reductions in K+ currents of the patient-derived variants, indicating a loss-of-function. In Drosophila, milder hyperexcitability phenotypes were observed in heterozygous Irk2 knock-in flies compared to homozygotes, supporting haploinsufficiency as the mechanism for the detected heterozygous variants. Electrophysiological recordings showed that excitatory neurons in Irk2 haploinsufficiency flies exhibited increased excitability, and glia-specific complementation with human Kir4.1 rescued the Irk2 mutant phenotypes.; Changed publications: 19289823, 19420365, 21849804, 11466414, 38979912; Changed phenotypes: SESAME syndrome, MIM# 612780, Paroxysmal dyskinesia, MONDO:0015427, KCNJ10-related; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Demonstrate in zebrafish that cfap20 is required for motile cilia function, and in C. elegans, CFAP-20 maintains the structural integrity of non-motile cilia inner junctions, influencing sensory-dependent signalling and development. Human patients and zebrafish with CFAP20 mutations both exhibit retinal dystrophy (retinitis pigments). Hence, CFAP20 functions within a structural./functional hub centred on the inner junction that is shared between motile and non-motile cilia, and is distinct from other ciliopathy-associaetd domains or macromolecular complexes. Describe 8 individuals from 4 independent families with damaging biallelic variants (homozygous or compound heterozygous) in CFAP20 that segregate with retinal dystrophy. All variants cluster to one side of the protein, with two of the residues directly contacting alpha-tubullin. Family 1 - consanguineous set of 3 siblings from Sudan, homozygous for CFAP20 c.305G>A; p.Arg102His (they also had a homozygous variant in DYNC1LI2 however CFAP20 was considered the better candidate. Family 2 - 3 siblings from Spain, 2 with retinal dystrophy, 1 genetically tested and has c.337C>T; p.(Arg113Trp) and c.397delC; p.(Gln133Serfs*5) Family 3 - single affected family member compound het for c.164+1G>A and c.457A>G; p.(Arg153Gly). Family 4 - 3 affected siblings with generalised retinopathy and variable neurological deficits with c.164+1G>A and c.257G>A; p.(Tyr86Cys) For all families, no individuals had signs of polycystic kidney disease; however, not all individuals had kidney imaging. Visual defecit phenotype presented between adolescence and adulthood (17-56 years old). Used HEK293T cell expression studies to demonstrate a statistically significant decline of mutated CFAP20 protein levels (with the exception of p.Arg102His).

Sources: Other Mode of inheritance for gene: NAA60 was set to BIALLELIC, autosomal or pseudoautosomal Phenotypes for gene: NAA60 were set to Basal ganglia calcification Review for gene: NAA60 was set to GREEN gene: NAA60 was marked as current diagnostic Added comment: ESHG 2023: 10 individuals from 7 families with biallelic variants in NAA60 (missense and framshift). All with primary brain calcification - 4/10 childhood onset (DD, ID), 6/10 adult onset (cerebellar and pyramidal dysfunction, dystonia, parkinsonism, cognitive impairment, psychiatric manifestations). NAA60 catalyses N-terminal acetylation of transmembrane proteins and localises to Golgi apparatus. In vitro assay of variants showed reduced capacity of Nt acetylation. Fibroblast studies showed significantly reduced levels of phosphate importer (SLC20A2). Loss of function variants in SLC20A2 (~50% of PFBC cases) lead to increased extracellular phosphate (which is thought to lead to calcium deposits in brain). Sources: Other |

(2023) Clin Genet. doi: 10.1111/cge.14389. Three siblings in one consanguineous Saudi Arabian family with non-syndromic neonatal diabetes, all with a homozygous frameshift variant, NM_001321425.2:c.1448dupA, p.(Tyr483*), in ZNF808. (Same nucleotide and amino acid numbering as for the MANE SELECT transcript, NM_001039886.4). This variant has been entered as likely pathogenic in ClinVar by this group. This variant occurs in the last exon of the gene and is therefore not NMD-predicted. Instead it is predicted to cause a truncated protein. This paper shows a diagram with several other truncating variants in this exon, which were reported in the paper by De Franco, E. et al. (2021). (These patients also had low vitamin D levels, suggesting an association, and is consistent with other studies looking into loci that are associated with vitamin D). De Franco, E. et al. (2021) medRxiv 08.23.21262262. (Exeter, UK): Firstly, this group found a homozygous variant NM_001039886.3:c.637del, p.(Leu213*) that is predicted to cause a truncated protein, and also a homozygous CNV Chr19(GRCh37):g.53057128_53100968del (predicted to cause a deletion of exons 4 and 5) in two unrelated affected individuals. These patients had pancreatic agenesis, defined as insulin-dependent diabetes in the first 6 months of life (neonatal diabetes) and exocrine pancreatic insufficiency. Both were from consanguineous families. Parents were subsequently tested and shown to be heterozygous carriers. They then investigated 232 additional patients who had been diagnosed with neonatal diabetes before the age of 6 months and found ten more homozygous ZNF808 variants. Six were nonsense: p.(Gln194*), p.(Cys233*), p.(Tyr427*), p.(Lys458*), p.(Tyr528*) and p.(Arg727*), and three were frameshift variants: p.(Ala379Valfs*157), p.(Leu588Profs*118), p.(Asn770Ilefs*98) and one was a whole-gene deletion. All the frameshift and nonsense variants occurred in the last exon of the gene, which contains all 23 zinc finger domains; and therefore all of these variants are predicted to result in truncated proteins, and removal of some, if not all, those domains. This group also carried out functional studies using an in vitro model of pancreas development and showed an aberrant activation of many transposable elements (mostly MER11 elements) that would be normally be repressed during early pancreas development.

Pathogenic variants in >20 genes encoding ciliary proteins have been found to cause OFDS. Identified by WES biallelic missense variants in a novel disease-causing ciliary gene RAB34 in four individuals from three unrelated families (aided by GeneMatcher). Affected individuals presented a novel form of OFDS accompanied by cardiac, cerebral, skeletal (eg. Shortening of long bones), and anorectal defects. RAB34 encodes a member of the Lab GTPase superfamily and was recently identified as a key mediator of ciliary membrane formation. Protein products of pathogenic variants clustered near the RAB34 C-terminus exhibit a strong loss of function. Onset is prenatal (multiple developmental defects including short femur, polydactyly, heart malformations, kidney malformations, brain malformations), resulting in medical termination for three probands. In the fourth, the only one alive at birth, proband born at 39+5 weeks, normal growth parameters after pregnancy with polyhydramnios, corpus callosum agenesis and polydactyly. Respiratory distress at birth. All four probands presented typical features of ciliopathy disorders, overlapping with oral, facial and digital abnormalities. All with homozygous missense variants.

Affected individuals presented with low-to-normal birth weight and infantile feeding difficulties but developed insulin resistance and hyperplasia during childhood. With the exception of an early truncating variant, the variants showed adequate nuclear translocation but overall disturbed DNA-binding ability and promoter activation. Variants absent from population and clinical databases. Almost all constituted putatively non-inherited de novo variants (8/10).

Mendeliome v1.711 | EPHA10 |
Achchuthan Shanmugasundram changed review comment from: Comment on rating: This gene should be rated RED as this gene has been associated with post-lingual autosomal dominant non-syndromic hearing loss from a single family, and supported by functional studies. PMID:36048850 reported the identification of a heterozygous non-coding variant c.-81_-73delinsAGC cosegregating with hearing loss. Although variants have been identified in KIF17 and USP48 in several members of this family, they did not cosegregate with hearing loss. One affected member of this family had an ideal hearing restoration after cochlear implantation. Epha10 was expressed in mouse cochlea at both transcription and translation levels. In addition, EPHA10 mRNA was detected upregulated in patients compared with controls by qRT-PCR. Overexpression of Eph (the homolog of human EPHA10) altered the structure and function of chordotonal organ (equivalent to mammalian auditory organs) in fly model. These functional evidence suggests that 'gain of function' may be responsible for the hearing loss phenotype. This gene has not yet been associated with any phenotypes in OMIM or Gene2Phenotype.

Homozygosity mapping led to identification of a a single nucleotide change, C65G, in TRU-TCA1-1, a tRNA in the selenocysteine incorporation pathway. This mutation resulted in reduction in expression of stress-related selenoproteins. A methylribosylation defect at uridine 34 of mutant tRNA observed in patient cells was restored by cellular complementation with normal tRNA.

Both chet for a missense and a splice site deletion- but the paper days these both result in the creation of a novel splice site that leads to frameshifts and loss of the c-terminal 64 amino acids. Gene is shown to be part of a spliceosome. CENATAC depletion or expression of disease mutants resulted in retention of introns in ~100 genes enriched for nucleocytoplasmic transport and cell cycle regulation, and caused chromosome segregation errors. Functional analysis in CENATAC-depleted HeLa cells demonstrated chromosome congression defects and subsequent mitotic arrest, which could be fully rescued by wildtype but not mutant CENATAC. Expression of the MVA-associated mutants exacerbated the phenotype, suggesting that the mutant proteins dominantly repress the function of any residual wildtype protein. Sources: Literature |

Treatment for Menkes disease: subcutaneous injections of copper histidine or copper chloride ClinGen has assessed as moderate evidence for actionability. Neonatal treatment with subcutaneous copper-histidine (initiated before 30 days of life) is recommended for asymptomatic males with a diagnosis of MD, but is not recommended for symptomatic boys or after 30 days of life. Treatment should be continued indefinitely. In an open-label clinical trial, 12 patients with MD treated with copper-histidine within 22 days of life had 92% survival after a mean follow-up of 4.6 years compared to 13% in a historical control group of 15 patients treated after a late diagnosis (mean age at diagnosis: 163 ± 113 days, range: 42 to 390). Two of the 12 patients with earlier treatment had normal neurological development. A second open-label trial of 35 presymptomatic patients receiving copper-histidine at less than a month of age reported significant improvement of four major neurodevelopmental (gross motor, fine motor/adaptive, personal/social, and language) domains and a non-significant lower mortality (28.5% vs 50%) at age of 3 years (or age of death) compared to 22 patients treated later and after onset of symptoms. |

Zornitza Stark gene: PTPA was added gene: PTPA was added to Mendeliome. Sources: Literature Mode of inheritance for gene: PTPA was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PTPA were set to 36073231 Phenotypes for gene: PTPA were set to Intellectual disability, MONDO: 36073231, PTPA-related Review for gene: PTPA was set to AMBER Added comment: Biallelic PTPA pathogenic variants lead to a form of ID with later-onset parkinsonism based on 4 individuals from 2 families in the literature. Affected individuals were homozygous for missense variants demonstrated to result to reduced mRNA and protein levels as well as PP2A complex activation. Drosophila studies support an age-dependent locomotor dysfunction. Variants in other PP2A-complex-related genes also lead to NDDs. Summary provided below. There is currently no associated phenotype in OMIM, G2P, PanelApp UK or SysID. Consider inclusion in relevant panels (ID, Parkinsonism/movement disorders, etc) with amber rating pending further reports. ------ Fevga, Tesson et al (2022 - PMID: 36073231) describe the features of 4 individuals, from 2 unrelated families, with biallelic pathogenic PTPA variants. These presented with normal or delayed early milestones, learning disability and ID (mild to moderate) followed by progressive signs of parkinsonism (at the age of 11 yrs in 2 sibs, 15 yrs in another individual). Motor symptoms were responsive to levodopa and later to deep brain stimulation. Linkage analysis in one consanguineous family followed by exome revealed homozygosity for a missense PTPA variant (NM_178001:c.893T>G/p.Met298Arg). Exome sequencing in affected subjects from the 2nd family revealed homozygosity for a further missense variant (c.512C>A/p.Ala171Asp). There were no other candidate variants for the phenotype following parental / segregation studies. Role of the gene: As the authors discuss, PTPA (or PPP2R4) is ubiquitously expressed in all tissues incl. brain and encodes a phosphotyrosyl phosphatase activator of the dimeric form of protein phosphatase-2A (PP2A). PP2A in turn, is the major Ser/Thr phosphatase in brain targeting a large number of proteins involved in diverse functions. Activation of PP2A is dependent on its methylation, which is negatively regulated by the PP2A-specific methylesterase (PME-1). By binding to PME-1, PTPA counteracts the negative influence of the former on PP2A. Pathogenic variants in genes encoding subunits/regulators of the PP2A complex (e.g. PPP2R1A or PPP2CA) are associated with neurodevelopmental disorders. Variant studies: Upon overexpression of wt and both variants in a HEK-293 cell line the authors demonstrated that both variants resulted in significantly reduced mRNA and protein levels (which for Ala171Asp were attributed to increased proteasomal degradation). Both variants were shown to result in impaired PP2A complex activation compared to wt. Drosophila / animal models: Pan-neuronal RNAi-mediated knockdown of ptpa in Drosophila resulted in an age-dependent locomotor dysfunction, reversible with L-DOPA treatment. Previous studies in mice suggest cognitive/electrophysiological impairments upon downregulation of PP2A activity in transgenic mice. Sources: Literature |

Zornitza Stark edited their review of gene: PMM2: Added comment: Association with HIPKD: Cabezas et al (2017) reported co-occurrence of hyperinsulinaemic hypoglycaemia and polycystic kidney disease (HIPKD in 17 children from 11 unrelated families. Patients presented with hyperinsulinaemic hypoglycaemia in infancy and enlarged kidneys with multiple kidney cysts. Some progressed to ESKD and some had liver cysts. Whole-genome linkage analysis in 5 informative families identified a single significant locus on chromosome 16p13.2. Sequencing of the coding regions of all linked genes failed to identify biallelic mutations. Instead, they found in all patients a promoter mutation (c.-167G>T) in PMM2, either homozygous or in trans with PMM2 coding mutations. They found deglycosylation in cultured pancreatic β cells altered insulin secretion. In vitro, the PMM2 promoter mutation associated with decreased transcriptional activity in patient kidney cells and impaired binding of the transcription factor ZNF143. In silico analysis suggested an important role of ZNF143 for the formation of a chromatin loop including PMM2. They proposed that the PMM2 promoter mutation alters tissue-specific chromatin loop formation, with consequent organ-specific deficiency of PMM2 leading to the restricted phenotype of HIPKD. None of the patients exhibited the typical clinical or diagnostic features of CDG1A. Serum transferrin glycosylation was normal in 11 patients who had assessment.; Changed publications: 28108845, 28373276, 32595772; Changed phenotypes: Congenital disorder of glycosylation, type Ia (MIM#212065), Hyperinsulinaemic Hypoglycaemia and Polycystic Kidney Disease (HIPKD), MONDO:0020642, PMM2-related |

Four affected (heterozygous) and two unaffected (neg) were tested, however 14 members had been diagnosed with HL in a large multi generational family (gene panel 237 genes). The second family (WES) had two affected heterozygous and no unaffected were tested. This same variant had previously been reported in a Danish family (12 affected heterozygous and 13 unaffected negative, but one younger member unaffected are heterozygous) with hearing loss (PMID: 26197441), for which functional studies in HEK cells demonstrated that the truncated protein was almost completely retained on the plasma cell membrane in contrast to the wild-type protein, which targeted primarily to the endo-lysosomal compartments. The YHTL motif, deleted by the c.574C>T nonsense mutation, is a canonical sorting motif known to be recognized by specific adaptor proteins in the cytosol, leading to subcellular trafficking of the transmembrane protein to endosomes and lysosomes.

Zornitza Stark changed review comment from: Sveinsson chorioretinal atrophy (SCRA) is characterized by bilateral, well-defined, tongue-shaped strips of atrophic retina and choroid that extend from the optic nerve into the peripheral ocular fundus. The lesions may be evident at birth and usually progress at a variable rate, sometimes leading to central visual loss. Separate small distinct circular atrophic lesions are observed in the peripheral ocular fundus in some patients. Congenital anterior polar cataracts are found in approximately 25% of affected individuals. The vast majority of reported cases were of Icelandic origin but the characteristic clinical picture of SCRA is also described in patients of non-Icelandic descent. The variant reported in the Icelanding population is (c.1261T>C, p.Tyr421His), another variant at same position c.1261T>A, p.Tyr421Asn also reported in non-Icelandic family. Functional data supports gene-disease association.; to: Sveinsson chorioretinal atrophy (SCRA) is characterized by bilateral, well-defined, tongue-shaped strips of atrophic retina and choroid that extend from the optic nerve into the peripheral ocular fundus.

Exome and genome sequencing identified 2 different homozygous variants in NAA20 gene (p.Met54Val and p.Ala80Val), and segregated with affected individuals. N-terminal acetyltransferases modify proteins by adding an acetyl moiety to the first amino acid and are vital for protein and cell function. The NatB complex acetylates 20% of the human proteome and is composed of the catalytic subunit NAA20 and the auxiliary subunit NAA25. Both NAA20-M54V and NAA20-A80V were impaired in their capacity to form a NatB complex with NAA25, and in vitro acetylation assays revealed reduced catalytic activities toward different NatB substrates.

Zornitza Stark changed review comment from: GoF variants cause Schinzel-Giedion syndrome, whereas LoF variants cause SETBP1-haploinsufficiency syndrome, over 40 individuals reviewed in PMID 34807554.; to: GoF variants cause Schinzel-Giedion syndrome, a severe multi-system disorder characterized by recognizable facial characteristics, severe-profound intellectual disability, intractable epilepsy, cortical visual impairment, deafness, and congenital anomalies such as cardiac defects, urogenital defects, and bone abnormalities. Causative pathogenic variants are clustered within a 12-base pair hot spot region in exon 4. LoF variants cause SETBP1-haploinsufficiency syndrome, characterized by hypotonia and mild motor developmental delay; intellectual abilities ranging from normal to severe disability; speech and language disorder; behavioral problems (most commonly attention/concentration deficits and hyperactivity, impulsivity), and refractive errors and strabismus.

They first analysed 4-generation Italian family with 6 individuals with hearing loss. The only rare variant segregating with the disease was a missense variant in USP48 (NM_032234.7:c.1216G > A, NP_115612.4:p.(Gly406Arg)). The variant is present in GnomAD v2.1.1 with a minor allele frequency (MAF) of 6.7 × 10−5 (17 allele out of 251 304 with no homozygotes). They also observed one hearing individual in the family who was heterozygous for the variant, suggesting incomplete penetrance. In a Dutch family the found by exome sequencing a missense variant in USP48 (NM_032236.7:c.2215_2216delinsTT, NP_115612.4:p.(Thr739Leu)). The probands mother and uncle were also affected by no sequence data was available for analysis. In a French family a proband is reported with right profound sensorineural hearing impairment (at 12 months), but normal left hearing (at 6 years old). The patient is heterozygote for a de novo splice variant in USP48 (NM_032236.7:c.3058 + 2 T > C, NP_115612.4:p.?;) which is not found in GnomAD and is predicted to result in a frameshift resulting in either NMD or a truncated protein. In functional experiments they showed that the two missense variants found in the Italian and Dutch families, and a shortened protein as predicted for the variant found in the French variant, showed an impaired ability to cleave tetra-ubiquitin into tri-, di- and mono-ubiquitin. Using immunohistology, they show that the human USP48 protein is present in fetal inner ear specimens. In addition zebrafish lacking usp48 showed a significant decrease of auditory response in acoustic startle response assays at 600 and 800 Hz wavelengths. Sources: Literature |

Shared phenotypic features include global developmental delay (9/10), brain anomalies (6/10), and eye anomalies (7/10). Seizures were predominantly reported in patients with monoallelic variants. Zebrafish studies showed an embryonic role of plxna1a in the development of the central nervous system and the eye. Biallelic variants in the extracellular Plexin-A1 domains lead to impaired dimerization or lack of receptor molecules, whereas monoallelic variants in the intracellular Plexin-A1 domains might impair downstream signaling through a dominant-negative effect.

(2018) used WES in a large consanguineous Israeli Arab kindred consisting of 16 patients affected with the neurogenic type of arthrogryposis multiplex congenita. They identified a homozygous missense (V98E) mutation in ERGIC1 gene, which segregated with the disorder in the kindred, and was not found in the ExAC database or in 212 ethnically matched controls. Functional studies of the variant and studies of patient cells were not performed. ERGIC1 encodes a cycling membrane protein which has a possible role in transport between endoplasmic reticulum and Golgi. Marconi et al (2021) used genome sequencing in a consanguineous family with 2 affected siblings presenting congenital arthrogryposis and some facial dysmorphism. They identified a homozygous 22.6 Kb deletion encompassing the promoter and first exon of ERGIC1. mRNA quantification showed the complete absence of ERGIC1 expression in the two affected siblings and a decrease in heterozygous parents.

Zornitza Stark gene: RNF220 was added gene: RNF220 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: RNF220 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: RNF220 were set to 33964137; 10881263 Phenotypes for gene: RNF220 were set to Leukodystrophy; CNS hypomyelination; Ataxia; Intellectual disability; Sensorineural hearing impairment; Elevated hepatic transaminases; Hepatic fibrosis; Dilated cardiomyopathy; Spastic paraplegia; Dysarthria; Abnormality of the corpus callosum Review for gene: RNF220 was set to GREEN Added comment: Sferra et al (2021 - PMID: 33964137) provide extensive evidence that biallelic RNF220 mutations cause a disorder characterized by hypomyelinating leukodystrophy, ataxia (9/9 - onset 1-5y), borderline intellectual functioning (3/9) / intellectual disability (5/9 - in most cases mild), sensorineural deafness (9/9) with complete hearing loss in the first decade of life, hepatopathy (9/9) with associated periportal fibrosis, and dilated cardiomyopathy (9/9) which was fatal. Other neurologic manifestations apart from ataxia incl. hyperreflexia (8/8), spastic paraplegia (9/9), dysarthria (9/9), peripheral neuropathy (4/9), seizures in one case (1/9). Upon brain MRI there was thin corpus callosum (9/9) or cerebellar atrophy in some (2/9). The authors identified homozygosity for 2 recurrent missense RNF220 variants in affected members belonging to these 5 broad consanguineous pedigrees (7 families), namely NM_018150.4:c.1094G>A / p.Arg365Gly in 4 Roma families in the context of a shared haplotype (/founder effect) as well as c.1088G>A / p.Arg363Gly in a large pedigree from southern Italy initially reported by Leuzzi et al (2000 - PMID: 10881263). Extensive segregation analyses were carried out including several affected and unaffected members. RNF220 encodes ring finger protein 220, which functions as an E3 ubiquitin ligase. Previous studies have shown among others a role in modulation of Sonic hedgehog/GLI signaling and cerebellar development Evidence for the role of RNF220 included relevant expression, localization within the cell, interaction partners (lamin B1, 20S proteasome), similarities with other laminopathies in terms of phenotype, etc : *RNF220 has a relevant expression pattern in CNS (based on qRT-PCR analyses in human brain, cerebellum, cerebral cortex / mRNA levels in human fetal CNS with higher expression in cerebellum, spinal cord and cortex / previous GTEx data / protein levels in mouse CNS) *The protein displays nuclear localization based on iPSC cells differentiated to motor neurons (also supported by data from the Human Protein Atlas). Transfection of COS-1 cells demonstrated localization primarily to the nucleus (as also previously demonstrated in HEK293T cells) in vesicle like structures with ASF2/SF2 colocalization suggesting enrichment in nuclear speckles. There was also partial co-distribution with the 20S proteasome. R363Q and R365Q additionally coalesced in the cytoplasm forming protein aggregates/inclusions. *Immunofluorescence studies in patient fibroblasts also confirmed abnormal increase of the protein in the cytoplasm and increased fluorescence with the 20S proteasome. *Proteomic identification of RNF220-interacting proteins in transfected HEK293T cells demonstrated enrichment for all members of the lamin protein family (incl . lamin B1, AC, B2). *RNAi-mediated downregulation of RNF222 in Drosophila suggested altered subcellular localization and accumulation of the fly orthologue for human lamin B1. *Immunoprecipitation of lamin B1 from the nuclear matrix of cerebellar cells suggested significant interaction of endogenous lamin B1 with RNF220, while transfection studies in HEK293T cells for wt/mt suggested reduced binding to endogenous lamin B1 for RNF220 mt compared to wt (more prominent for R365Q). RNF220 mutants also reduced ubiquitination of nuclear lamin B1 compared to wt. *Patient fibroblasts immunostained with different nuclear envelope markers displayed abnormal nuclear shapes with multiple invaginations and lobulations, findings also observed in laminopathies.

Mendeliome v0.8829 | ARF3 |
Zornitza Stark gene: ARF3 was added gene: ARF3 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: ARF3 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: ARF3 were set to 34346499 Phenotypes for gene: ARF3 were set to Global developmental delay; Intellectual disability; Seizures; Morphological abnormality of the central nervous system Review for gene: ARF3 was set to AMBER Added comment: Sakamoto et al (2021 - PMID: 34346499) provide some evidence that monoallelic ARF3 pathogenic variants may be associated with a NDD with brain abnormality. Using trio exome sequencing, the authors identified 2 individuals with NDD harboring de novo ARF3 variants, namely: NM_001659.2:c.200A>T / p.Asp67Val and c.296G>T / p.Arg99Leu. Individual 1 (with Asp67Val / age : 4y10m), appeared to be more severelely affected with prenatal onset progressive microcephaly, severe global DD, epilepsy. Upon MRI there was cerebellar and brainstem atrophy. Individual 2 (Arg99Leu / 14y) had severe DD and ID (IQ of 23), epilepsy and upon MRI cerebellar hypoplasia. This subject did not exhibit microcephaly. Common facial features incl. broad nose, full cheeks, small philtrum, strabismus, thin upper lips and abnormal jaw. There was no evidence of systemic involvement in both. ARF3 encodes ADP-ribosylation factor 3. Adenosine diphosphate ribosylation factors (ARFs) are key proteins for regulation of cargo sorting at the Golgi network, with ARF3 mainly working at the trans-Golgi network. ARFs belong to the small GTP-binding protein (G protein) superfamily. ARF3 switches between an active GTP-bound form and an inactive GDP-bound form, regulated by guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs) respectively. Members of the ARF superfamily regulate various aspects of membrane traffic, among others in neurons. There are 5 homologs of ARF families, divided in 3 classes. ARF3 and ARF1 belong to class I. Monoallelic ARF1 mutations are associated with Periventricular nodular heterotopia 8 (MIM 618185). In vivo, in vitro and in silico studies for the 2 variants suggest that both impair the Golgi transport system although each variant most likely exerts a different effect (gain-of-function for Arg99Leu vs loss-of-function/dominant-negative for Asp67Val). This was also reflected in somewhat different phenotype of the subjects with the respective variants. Common features included severe DD, epilepsy and brain abnormalities although Asp67Val was associated with diffuse brain atrophy as well as congenital microcephaly and Arg99Leu with cerebellar hypoplasia. Evidence to support the effect of each variant include: Arg99Leu: Had identical Golgi localization to that of wt Had increased binding activity with GGA1, a protein recruited by the GTP-bound active form of ARF3 to the TGN membrane (supporting GoF) In silico structural analysis suggested it may fail to stabilize the conformation of Asp26, resulting in impaired GTP hydrolysis (GoF). In transgenic fruit flies, evaluation of the ARF3 variant toxicity using the rough eye phenotype this variant was associated with increased severity of the r-e phenotype similar to a previously studied GoF variant (Gln71Leu) Asp67Val: Did not show a Golgi-like pattern of localization (similar to Thr31Asn a previously studied dominant-negative variant) Displayed decreased protein stability In silico structural analysis suggested that Asp67Val may lead to compromised binding of GTP or GDP (suggestive of LoF) In transgenic Drosophila eye-specific expression of Asp67Val (similar to Thr31Asn, a known dominant-negative variant) was lethal possibly due to high toxicity in very small amounts in tissues outside the eye. There is no associated phenotype in OMIM, G2P or SysID. Sources: Literature |

The index patient from the 1st family presented with CHD (hypoplastic right ventricle, ASD), DD and moderate ID (IQ of 40), failure to thrive as well as some dysmorphic features (obtuse mandibular angle, mild overbite, synophrys with downslanting p-f, strabismus, etc). There were additional features (eg. postaxial polydactyly) which were found in other affected and unaffected family members. Exome sequencing with autozygome analysis revealed homozygosity for a PLXNA2 stopgain variant (NM_025179:c.3603C>A / p.(Cys1201*)). Sanger confirmation was carried out and segregation analyses confirmed carrier status of the unaffected parents and a sib as well as a brother homozygous for the same variant. Clinical evaluation of the latter, following this finding revealed borderline intellectual functioning, ADHD, failure to thrive. There was no mandibular anomaly or overbite and no clinical evidence of CHD (no echo performed). The index patient from the 2nd consanguineous family was evaluated for ID (IQ of 63), with previous borderline motor development, ADHD and some dysmorphic features (obtuse mandibular angle and overbite). There was no clinical evidence of CHD (no echo performed). Exome sequencing with autozygosity mapping revealed a homozygous missense PLXNA2 variant (c.3073G>A / p.(Asp1025Asn), present only once in gnomAD (htz), with rather non-concordant in silico predictions SIFT 0.22, PolyPhen 0.682 and CADD 23.5. The aa was however highly conserved. Segregation analysis confirmed carrier state of the parents and 2 unaffected sibs, with a 3rd sib homozygous for the wt allele. As the authors discuss: *PLXNA2 belongs to the plexin family of genes, encoding transmbembrane proteins functioning as semaphorin receptors. It has predominant expression in neural tissue. The protein is thought to bind semaphorin-3A, -3C or -5 followed by plexin A2 dimerization, activation of its GTPase-activating protein domain, negative regulation of Rap1B GTPase and initiation of a signal transduction cascade mediating axonal repulsion/guidance, dendritic guidance, neuronal migration. *Murine Plxna2 knockout models display structural brain defects. In addition they display congenital heart defects incl. persistent truncus arteriosus and interrupted aortic arch. *Rare CNVs in adult humans with tetralogy of Fallot have suggested a potential role of PLXNA2 in cardiac development and CHD. *Expression and the role of PLXNA2 in human chondrocytes as well as a GWAS in 240 japanese patients with mandibular prognathism where PLXNA2 was suggested as a susceptibility locus. Overall, the authors recognize some common features (as for cognitive functioning, some dysmorphic features incl. obtuse mandibular angle and overbite in 2 unrelated subjects, failure to thrive 3/3) and provide plausible explanations for the variability / discordance of others eg: - Cyanotic heart disease explaining discordance in cognitive outcome among sibs - Incomplete penetrance for CHD (and/or ID or mandibular anomaly) as for few AR disorders and/or - Additional pathogenic variants possibly explaining the CHD in the first subject. There is no associated phenotype in OMIM or G2P. SysID includes PLXNA2 among the candidate ID genes. Sources: Literature |

Mendeliome v0.8807 | VPS50 |

Sources: Literature Mode of inheritance for gene: VPS50 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: VPS50 were set to 34037727 Phenotypes for gene: VPS50 were set to Neonatal cholestatic liver disease; Failure to thrive; Profound global developmental delay; Postnatal microcephaly; Seizures; Abnormality of the corpus callosum Review for gene: VPS50 was set to AMBER Added comment: Schneeberger et al (2021 - PMID: 34037727) describe the phenotype of 2 unrelated individuals with biallelic VPS50 variants. Common features included transient neonatal cholestasis, failure to thrive, severe DD with failure to achieve milestones (last examination at 2y and 2y2m respectively), postnatal microcephaly, seizures (onset at 6m and 25m) and irritability. There was corpus callosum hypoplasia on brain imaging. Both individuals were homozygous for variants private to each family (no/not known consanguinity applying to each case). The first individual was homozygous for a splicing variant (NM_017667.4:c.1978-1G>T) and had a similarly unaffected sister deceased with no available DNA for testing. The other individual was homozygous for an in-frame deletion (c.1823_1825delCAA / p.(Thr608del)). VPS50 encodes a critical component of the endosome-associated recycling protein (EARP) complex, which functions in recycling endocytic vesicles back to the plasma membrane [OMIM based on Schindler et al]. The complex contains VPS50, VPS51, VPS52, VPS53, the three latter also being components of GARP (Golgi-associated-retrograde protein) complex. GARP contains VPS54 instead of VPS50 and is required for trafficking of proteins to the trans-golgi network. Thus VPS50 (also named syndetin) and VPS54 function in the EARP and GARP complexes, to define directional movement of their endocytic vesicles [OMIM based on Schindler et al]. The VPS50 subunit is required for recycling of the transferrin receptor. As discussed by Schneeberger et al (refs provided in text): - VPS50 has a high expression in mouse and human brain as well as throughout mouse brain development. - Mice deficient for Vps50 have not been reported. vps50 knockdown in zebrafish results in severe developmental defects of the body axis. Knockout mice for other proteins of the EARP/GARP complex (e.g. Vps52, 53 and 54) display embryonic lethality. Studies performed by Schneeberger et al included: - Transcript analysis for the 1st variant demonstrated skipping of ex21 (in patient derived fabriblasts) leading to an in frame deletion of 81 bp (r.1978_2058del) with predicted loss of 27 residues (p.Leu660_Leu686del). - Similar VPS50 mRNA levels but significant reduction of protein levels (~5% and ~8% of controls) were observed in fibroblasts from patients 1 and 2. Additionally, significant reductions in the amounts of VPS52 and VPS53 protein levels were observed despite mRNA levels similar to controls. Overall, this suggested drastic reduction of functional EARP complex levels. - Lysosomes appeared to have similar morphology, cellular distribution and likely unaffected function in patient fibroblasts. - Transferrin receptor recycling was shown to be delayed in patient fibroblasts suggestive of compromise of endocytic-recycling function. As the authors comment, the phenotype of both individuals with biallelic VPS50 variants overlaps with the corresponding phenotype reported in 15 subjects with biallelic VPS53 or VPS51 mutations notably, severe DD/ID, microcephaly and early onset epilepsy, CC anomalies. Overall, for this group, they propose the term "GARP and/or EARP deficiency disorders". There is no VPS50-associated phenotype in OMIM or G2P. SysID includes VPS50 among the ID candidate genes.

Mendeliome v0.8741 | TCF7L2 |
Zornitza Stark changed review comment from: 2 reviews Konstantinos Varvagiannis (Other) I don't know Dias et al (2021 - PMID: 34003604) describe the phenotype of 11 unrelated individuals harboring de novo missense/truncating TCF7L2 variants. Features included DD in childhood (motor delay in 8/11, speech delay in 11/11), intellectual abilities ranging from average cognitive functioning to mild/moderate ID (the latter observed in 5/11), myopia (6/11) , dysmorphic features, variable orthopedic findings, and neuropsychiatric comorbidities incl. ASD (4/11) / ADHD (4/11). One additional (12th) individual was excluded from this summary due to concurrent diagnosis of hypoxic-ischemic injury. TCF7L2 on 10q25 encodes transcription factor 7-like 2, a high mobility group (HMG) box-containing transcription factor. As the authors discuss, the protein mediates canonical Wnt signaling. Secreted Wnt proteins lead to release of beta-catenin (CTNNB1) which after translocation to the nucleus acts with DNA-binding factors incl. TCF7L2 to turn on Wnt-responsive target genes. As a result TCF7L2 acts with beta-catenin as a switch for transcriptional regulation. Multiple alternative spliced TCF7L2 transcripts mediate it's function and specificity of transcriptional repertoire in a variety of tissues and contexts. Dias et al provide references for its role in nervous system development incl. neurogenesis and thalamic development. Variants in all cases occurred as de novo events with pLoF (stopgain, frameshift, splicing) ones predicted to lead to NMD. Missense variants occurred in all cases in or adjacent to the HMG box domain [aa 350-417]. 5 different missense variants affecting 3 residues were reported incl. c.1142A>C, c.1143C>G (leading to Asn381Thr/Lys respectively), c.1250G>T (Trp417Leu), c.1267T>C, c.1268A>G (leading to Tyr423His/Cys) [NM_001146274.1]. The gene has a pLI of 0.99-1 gnomAD/ExAC while there is a region of missense constraint encompassing the HMG box domain (the latter is an evolutionary conserved region mediating interactions with DNA). No phenotypic differences were observed among individuals with pLoF and missense SNVs, and haploinsufficiency is presumed to be the underlying mechanism. There are no variant or other studies performed, nor any animal models discussed. In supplementary table 2, the authors provide several references to previous large scale sequencing studies with brief/incomplete descriptions of individuals de novo TCF7L2 variants and neurodevelopmental disorder (ID/ASD - Iossifov, De Rubeis, Lelieveld, McRae/DDD study and many other Refs).

Biallelic PIDD1 pathogenic variants have been reported in 26 individuals (11 families) with DD (all), variable degrees of ID (mild to severe), behavioral (eg. aggression/self-mutilation in several, ADHD) and/or psychiatric abnormalities (ASD, psychosis in 5 belonging to 3 families), well-controlled epilepsy is some (9 subjects from 6 families) and MRI abnormalities notably abnormal gyration pattern (pachygyria with predominant anterior gradient) as well as corpus callosum anomalies (commonly thinning) in several. Dysmorphic features have been reported in almost all, although there has been no specific feature suggested. The first reports on the phenotype associated with biallelic PIDD1 mutations were made by Harripaul et al (2018 - PMID: 28397838) and Hu et al (2019 - PMID: 29302074) [both studies investigating large cohorts of individuals with ID from consanguineous families]. Sheikh et al (2021 - PMID: 33414379) provided details on the phenotype of 15 individuals from 5 families including those from the previous 2 reports and studied provided evidence on the role of PIDD1 and the effect of variants. Zaki et al (2021 - PMID: 34163010) reported 11 additional individuals from 6 consanguineous families, summarize the features of all subjects published in the literature and review the neuroradiological features of the disorder. PIDD1 encodes p53-induced death domain protein 1. The protein is part of the PIDDosome, a multiprotein complex also composed of the bipartite linker protein CRADD (also known as RAIDD) and the proform of caspase-2 and induces apoptosis in response to DNA damage. There are 5 potential PIDD1 mRNA transcript variants with NM_145886.4 corresponding to the longest. Similar to the protein encoded by CRADD, PIDD1 contains a death domain (DD - aa 774-893). Constitutive post-translational processing gives PIDD1-N, PIDD1-C the latter further processed into PIDD1-CC (by auto-cleavage). Serine residues at pos. 446 and 588 are involved in this autoprocessing generating PIDD1-C (aa 446-910) and PIDD1-CC (aa 774-893). The latter is needed for caspase-2 activation. Most (if not all) individuals belonged to consanguineous families of different origins and harbored pLoF or missense variants. Variants reported so far include : c.2587C>T; p.Gln863* / c.1909C>T ; p.Arg637* / c.2443C>T / p.Arg815Trp / c.2275-1G>A which upon trap assay was shown to lead to skipping of ex15 with direct splicing form exon14 to the terminal exon 16 (resulting to p.Arg759Glyfs*1 with exlcusion of the entire DD) / c.2584C>T; p.Arg862Trp / c.1340G>A; p.Trp447* / c.2116_2120del; p.Val706His*, c.1564_1565del; p.Gly602fs*26 Evidence so far provided includes: - Biallelic CRADD variants cause a NDD disorder and a highly similar gyration pattern. - Confirmation of splicing effect (eg. for c.2275-1G>A premature stop in position 760) or poor expression (NM_145886.3:c.2587C>T; p.Gln863*). Arg815Trp did not affect autoprocessing or protein stability. - Abnormal localization pattern, loss of interaction with CRADD and failure to activate caspase-2 (MDM2 cleavage assay) [p.Gln863* and Arg815Trp] - Available expression data from GTEx (PIDD1 having broad expression in multiple tissues, but higher in brain cerebellum) as well as BrainSpan and PsychEncode studies suggesting high coexpression of PIDD1, CRADD and CASP2 in many regions in the developing human brain. - Variants in other genes encoding proteins interacting with PIDD1 (MADD, FADD, DNAJ, etc) are associated with NDD. Pidd-1 ko mice (ex3-15 removal) lack however CNS-related phenotypes. These show decreased anxiety but no motor anomalies. This has also been the case with Cradd-/- mice displaying no significant CNS phenotypes without lamination defects. There is currently no associated phenotype in OMIM. PIDD1 is listed in the DD panel of G2P (PIDD1-related NDD / biallelic / loss of function / probable) . SysID includes PIDD1 among the current primary ID genes. Sources: Expert Review |

Sources: Literature Mode of inheritance for gene: SF3B2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: SF3B2 were set to 34344887 Phenotypes for gene: SF3B2 were set to Craniofacial microsomia Review for gene: SF3B2 was set to GREEN Added comment: Twenty individuals from seven families reported with de novo or transmitted haploinsufficient variants in SF3B2. Affected individuals had mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities. Targeted morpholino knockdown of SF3B2 in Xenopus resulted in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease. The families were ascertained from a cohort and the authors suggest that haploinsufficient variants in SF3B2 are the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases.

Mendeliome v0.8583 | PRDX3 |
Hazel Phillimore changed review comment from: Biallelic variants in 5 unrelated families with early onset (median 21 years , range 13-22 years) with ataxia with variable additional hyper- and hypokinetic movement disorders, and severe early-onset cerebellar atrophy (seen on MRI), and involvement of the brainstem, medullary olive and parietal cortex. Evolution of the disease was gait ataxia leading to upper limb ataxia, then dysarthria and then dysphagia, all within a decade. For some of these patients, the phenotype included myoclonus, dystonia and / or tremor. Mild classical mitochondrial features were seen in one of the patients, namely ptosis and COX-negative fibres. The variants were homozygous nonsense, homozygous frameshift, homozygous missense, and a compound heterozygote of a splice variant and missense, all leading to complete loss of the protein. Oxidative stress and mitochondrial dysfunction was indicated as the disease mechanism. The families originated from Germany, France, India and two from eastern Turkey. The two families from Turkey were seemingly unrelated to each other but had the same homozygous missense. Patient fibroblasts from each of the five probands showed lack of protein (via Western blot) and decreased glutathione peroxidase activity and decreased mitochondrial maximal respiratory capacity. PRXD3 encodes peroxiredoxin 3, a mitochondrial antioxidant protein, that catalyses the reduction of hydrogen peroxide. It localises in the mitochondria, where most hydrogen peroxide is generated. Functional studies: PRDX3 knockdown (induced by silencing RNA against PRDX3) in cerebellar medulloblastoma cells showed significantly decreased cell viability, increased hydrogen peroxide levels and increased susceptibility to apoptosis triggered by reactive oxygen species. In addition, induced knockdown drosophila (in vivo animal model) had aberrant locomotor phenotypes and reduced lifespans, while immunolabelling of the brain showed increased cell death after exposure to oxidative stress.

Features included DD, ID (7/7 for whom this information was available), ASD or autistic features (4/7). MRI abnormalities were observed in 3 (widening of CSF spaces, periventricular nodular heterotopia, prominent lat. ventricles). Epilepsy (myoclonic-astatic epilepsy / Doose syndrome) was reported for 2(/8) individuals. The 3 patients here reported were identified following trio/singleton exome with Sanger confirmation of the variants and their de novo occurrence. Variants are in almost all cases de novo (7/7 for whom this was known) and in 5/8 cases were pLoF, in 2/8 missense SNVs while a case from DECIPHER had a 77.92 kb whole gene deletion not involving other genes with unknown inheritance.

As the authors note, this RNA-binding protein is involved in multiple pathways associated with neuronal/muscular developmental disorders. Several references are provided for its involvement in regulation of RNA metabolism, among others sequence recognition, pre-mRNA splicing, translation, transport and degradation. Mutations in other RNA-interacting proteins and hnRNP members (e.g. HNRNPU, HNRNPD) are associated with NDD. The missense variant (p.Leu245Pro) is within RRM2 one of the 3 RNA recognition motif (RRM) domains of the protein. These 3 domains, corresponding to the central part of the protein (aa 150-400), are relatively intolerant to variation (based on in silico predictions and/or variation in gnomAD). Leu245 localizes within an RNA binding pocket and in silico modeling suggests alteration of the tertiary structure and RNA-binding capacity of RRM2. There are no additional studies performed. Overall haploinsufficiency appears to be the underlying disease mechanism based on the truncating variants and the gene deletion. [pLI in gnomAD : 1, %HI : 2.48%] Animal models are not discussed. There is no associated phenotype in OMIM. This gene is included in the DD panel of G2P (monoallelic LoF variants / SYNCRIP-related developmental disorder).

Overlapping features included DD (13/13), ID (10/10 - mild in most cases, individuals with larger CNVs/additional variants had more severe phenotype), speech delay and behavioral disorders. Variable other features incl. hypotonia (70%), non specific facial features, eye abnormalities (40%) and cardiac defects (25%). The CNVs ranged from 152 kb to few Mb in size but in 4 subjects (P5-8) were only minimal, involving only EPHA7. 9 out of 12 individuals had inherited the deletion (5 subjects paternal, 4 maternal), in 1 subject (P12) this occured de novo, while for 2 others inheritance was not specified. Most deletions were inherited from an unaffected parent (in 6/7 families), with unclear contribution in a further one. The authors discuss on previous studies suggesting an important role for EphA7 in brain development (modulation of cell-cell adhesion and repulsion, regulation of dendrite morphogenesis in early corticogenesis, role in dendritic spine formation later in development. EphA7 has also been proposed to drive neuronal maturation and synaptic function). Haploinsufficiency for other ephrins or ephrin receptors has been implicated in other NDDs. Overall Lévy et al promote incomplete penetrance and variable expressivity with haploinsufficiency of this gene being a risk factor for NDD. [The gene has also an %HI of 2.76% and a pLI of 1].

The phenotype is highly variable, but most patients have features of a systemic vascular inflammatory disorder with skin ulceration and recurrent strokes affecting the small vessels of the brain resulting in neurologic dysfunction. Other features may include recurrent fever, elevated acute-phase proteins, myalgias, lesions resembling polyarteritis nodosa, and/or livedo racemosa or reticularis with an inflammatory vasculitis on biopsy. Some patients may have renal and/or gastrointestinal involvement, hypertension, aneurysms, or ischemic necrosis of the digits. Some affected individuals have immunodeficiency.

Other components have been linked to disease with phenotypes including microcephaly and ID. MCM7 is not associated with any phenotype in OMIM or G2P at present. ------ Currently there are 3 unrelated pedigrees in literature with different biallelic MCM7 variants associated with disease (see below). Although there is some functional data in support of variant-level deleteriousness or gene-level pathogenicity, the clinical gestalt is very different between the 3 families. - PMID: 33654309 (2021) - Two unrelated individuals with different compound het variants in MCM7 but disparate clinical features. One patient had typical Meier-Gorlin syndrome (including growth retardation, microcephaly, congenital lung emphysema, absent breast development, microtia, facial dysmorphism) whereas the second case had a multi-system disorder with neonatal progeroid appearance, lipodystrophy and adrenal insufficiency. While small at birth, the second patient did not demonstrate reduced stature or microcephaly at age 14.5 years. Both individuals had normal neurodevelopment. Functional studies using patient-derived fibroblasts demonstrate that the identified MCM7 variants were deleterious at either transcript or protein levels and through interfering with MCM complex formation, impact efficiency of S phase progression. - PMID: 34059554 (2021) - Homozygous missense variant identified in three affected individuals from a consanguineous family with severe primary microcephaly, severe ID and behavioural abnormalities. Knockdown of Mcm7 in mouse neuroblastoma cells lead to reduced cell viability and proliferation with increased apoptosis, which were rescued by overexpression of wild-type but not mutant MCM7.

Type A NPD patients exhibit hepatosplenomegaly in infancy and profound CNS involvement. They rarely survive beyond 2-3years of age. Type B patients also have hepatosplenomegaly and pathologic alterations of their lungs, but there are usually no CNS signs. The age of onset and rate of disease progression varies greatly among type B patients, and they frequently live into adulthood.

Authors state that not all features of the individual could be explained by the RPS6KA3 variant, and that consideration of Coffin-Lowry sysndrome was only made after identification of the RPS6KA3 variant. Therefore individual has there is a blended phenotype of Coffin–Lowry syndrome and Sjögren–Larsson syndrome. From functional studies authors propose that the ALDH1L2 loss induces mitochondrial dysfunction due to reduced NADPH and increased oxidative stress (PMID: 31341639). Knockout mouse model was viable and did not show an apparent phenotype, however metabolomic analysis showed vastly changed metabotypes in the liver and plasma in these mice suggesting channeling of fatty acids away from β-oxidation. Authors therefore postulate that the role of ALDH1L2 in the lipid metabolism explains why the loss of this enzyme is associated with neuro-cutaneous disease. Sources: Literature |

Affected individuals usually do not acquire ambulation, show progressive spasticity, and have impaired intellectual development with absent speech. More variable features may include pale optic discs, poor eye contact, seizures, and congenital heart defects. Laboratory studies show increased serum lactate; metabolic acidosis may occur during stress or infection. Brain imaging shows T2-weighted abnormalities in the basal ganglia and brainstem, consistent with a clinical diagnosis of Leigh syndrome. Two unrelated families reported, some functional data.

Less common features include a reduced number of alveoli and a patchy distribution of the histopathologic changes. The disorder is associated with persistent pulmonary hypertension of the neonate and shows varying degrees of lability and severity. Affected infants present with respiratory distress resulting from pulmonary hypertension in the early postnatal period, and the disease is uniformly fatal within the newborn period. Additional features of ACDMPV include multiple congenital anomalies affecting the cardiovascular, gastrointestinal, genitourinary, and musculoskeletal systems, as well as disruption of the normal right-left asymmetry of intrathoracic or intraabdominal organs.; to: Congenital alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is characterized histologically by failure of formation and ingrowth of alveolar capillaries that then do not make contact with alveolar epithelium, medial muscular thickening of small pulmonary arterioles with muscularization of the intraacinar arterioles, thickened alveolar walls, and anomalously situated pulmonary veins running alongside pulmonary arterioles and sharing the same adventitial sheath.

The variants were located in the N-terminal domain of the A isoform of FGF13/FHF2 (FHF2A). The X-linked FHF2 gene (also known as FGF13) has alternative first exons which produce multiple protein isoforms that differ in their N-terminal sequence. The variants were located at highly conserved residues in the FHF2A inactivation particle that competes with the intrinsic fast inactivation mechanism of Nav channels. Functional characterization of mutant FHF2A co-expressed with wild-type Nav1.6 (SCN8A) revealed that mutant FHF2A proteins lost the ability to induce rapid-onset, long-term blockade of the channel while retaining pro-excitatory properties. These gain-of-function effects are likely to increase neuronal excitability consistent with the epileptic potential of FHF2 variants. Sources: Literature |

Marbach et al. (2020 - medRxiv : https://doi.org/10.1101/2020.09.10.20190314 - last author : C. Schaaf) report 6 unrelated individuals with heterozygous missense PRKAR1B variants. All presented formal ASD diagnosis (6/6), global developmental delay (6/6) and intellectual disability (all - formal evaluations were lacking though). Additional features included neurologic anomalies (movement disorders : dyspraxia, apraxia, clumsiness in all, with tremor/dystonia or involuntary movements as single occurrences). Three displayed high pain tolerance. Regression in speech was a feature in two. Additional behavior anomalies included ADHD (4-5/6) or aggression (3/6). There was no consistent pattern of malformations, physical anomalies or facial features (with the exception of uplsanted palpebral fissures reported in 4). 3 different missense variants were identified (NM_00116470:c.1003C>T - p.Arg335Trp, c.586G>A - p.Glu196Lys, c.500_501delAAinsTT - p.Gln167Leu) with Arg355Trp being a recurrent one within this cohort (4/6 subjects). A possible splicing effect may apply for the MNV. All variants are absent from gnomAD and the SNVs had CADD scores > 24. In all cases were parental samples were available (5/6), the variant had occurred as a de novo event. Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes. As the authors comment, the RIβ subunit is primarily expressed in brain with higher expression in cortex and hypothalamus. The functional consequences of the variants at cellular level were not studied. Previous studies have demonstrated that downregulation of RIβ in murine hippocampal cultures, reduced phosphorylation of CREB, a transcription factor involved in long-term memory formation. The authors speculate that a similar effect on cAMP/PKA/CREB cascade may mediate the cognitive effects in humans. RIβ deficient mice also display diminished nociceptive pain, similar to the human phenotype. [Several refs provided]. The authors cite the study by Kaplanis et al (2020 - PMID: 33057194), where in a large sample of 31,058 trio exomes of children with developmental disorders, PRKAR1B was among the genes with significant enrichment for de novo missense variants. [The gene has a pLI score of 0.18 in gnomAD / o/e = 0.26 - so pLoF variants may not be deleterious]. Please note that a specific PRKAR1B variant (NM_002735.2:c.149T>G - p.Leu50Arg) has been previous reported to segregate with a late-onset neurodegenerative disorder characterized by dementia and/or parkinsonism within a large pedigree with 12 affected individuals [Wong et al 2014 - PMID: 25414040].

Sources: Literature Mode of inheritance for gene: MPP5 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: MPP5 were set to 33073849 Phenotypes for gene: MPP5 were set to Global developmental delay; Intellectual disability; Delayed speech and language development; Developmental regression; Behavioral abnormality Penetrance for gene: MPP5 were set to unknown Review for gene: MPP5 was set to GREEN Added comment: Sterling et al (2020 - PMID: 33073849) provide information on the phenotype of 3 individuals with de novo MPP5 variants. Common features included global developmental delay, intellectual disability (3/3 - severe in 2/3), speech delay/regression (the latter in at least 2) and behavioral abnormalities. Variable other features were reported, among others microcephaly (1/3), abnormal vision (1/3 : CVI, retinal dystrophy, nystagmus), brain MRI abnormalities (2/3), late-onset seizures (1/3). These subjects displayed variable and non-specific dysmorphic features. All were investigated by exome sequencing (previous investigations not mentioned). One subject was found to harbor a de novo mosaic (5/25 reads) stopgain variant, further confirmed by Sanger sequencing [NM_022474.4:c.1555C>T - p.(Arg519Ter). The specific variant is reported once in gnomAD (1/251338). Two de novo missense variants were identified in the remaining individuals [c.1289A>G - p.Glu430Gly / c.974A>C - p.His325Pro). All variants had in silico predictions in favor of a deleterious effect (CADD score >24). The authors comment that MPP5 encodes an apical complex protein with asymmetric localization to the apical side of polarized cells. It is expressed in brain, peripheral nervous system and other tissues. MPP5 is a member of the membrane-associated guanylate kinase family of proteins (MAGUK p55 subfamily), determining cell polarity at tight junctions. Previous animal models suggest that complete Mpp5(Pals1) KO in mice leads to near absence of cerebral cortical neurons. Htz KO display reduction in size of cerebral cortex and hippocampus. The gene is expressed in proliferating cell populations of cerebellum and important for establishment cerebellar architecture. Conditional KO of Mpp5(Pals1) in retinal progenitor cells mimics the retinal pathology observed in LCA. [Several refs. provided] The authors studied a heterozygous CNS-specific Mpp5 KO mouse model. These mice presented microcephaly, decreased cerebellar volume and cortical thickness, decreased ependymal cells and Mpp5 at the apical surface of cortical vertrical zone. The proportion of cortical cells undergoing apoptotic cell death was increased. Mice displayed behavioral abnormalities (hyperactivity) and visual deficits, with ERG traces further suggesting retinal blindness. Overall the mouse model was thought to recapitulate the behavioral abnormalities observed in affected subjects as well as individual rare features such as microcephaly and abnormal vision. Haploinsufficiency (rather than a dominant negative effect) is favored as the underlying disease mechanism. This is also in line with a dose dependent effect observed in mice. Sources: Literature |

Mendeliome v0.4520 | SLC12A2 |
Zornitza Stark edited their review of gene: SLC12A2: Added comment: Monoallelic : DD/ID was a feature in >= 6 individuals with monoallelic de novo SLC12A2. An individual with an exon 22 truncating variant was reported to have normal milestones and cognitive function. Exon 21 variants have been described in individuals with rather isolated hearing impairment (possibly some associated motor delay, but normal cognition). Hearing impairment was also reported in 2/6 patients with variants in other exons (1 missense / 1 frameshift). Biallelic : DD/ID was reported in at least 3 individuals in literature. Hearing impairment has been reported on 2 occasions (although this was not probably evaluated in all subjects). --- Monoallelic SLC12A2 mutations : ► Individuals with de novo mutations and developmental disorder were first identified by the DDD study (2017 - PMID: 28135719). 5 of them have been reported in detail by McNeill et al (below). ► McNeill et al (2020 - PMID: 32658972) report on 6 individuals with neurodevelopmental disorder due to de novo SLC12A2 mutation. All presented DD or ID ranging from mild to severe. ASD was reported in 3/6. Sensorineural hearing loss was a feature in 2/6 with the remaining having normal formal evaluations. Brain, cardiac and/or additional malformations were reported in a single individual. Following non-diagnostic prior work-up (CMA, FMR1 or other investigations) trio exome sequencing revealed missense (4/6) or truncating variants (2/6). Three additional individuals (incl. a father and his son) with missense variants in exon 21 (NM_001046.3 / p.Glu979Lys and p.Glu980Lys) presented with bilateral sensorineural hearing loss. Speech and/or motor delay reported in these cases were attributed to the hearing impairment/vestibular arreflexia (cognitive abilities not tested). SLC12A2 encodes sodium-potassium-chloride transporter 1 (also NKCC1). The GTEx project has identified 8 isoforms. In brain both exon 21-containing/deleted isoforms are expressed (cited Morita et al 2014 - PMID: 24695712). As the authors discuss, RNA-seq of the developing mouse cochlea suggests that the exon 21 containing isoform is the single transcript expressed. Evidence from RNA-seq data (BrainSpan project) and literature suggests that the significant amounts of exon 21 lacking isoforms in fetal brain compensate for the deleterious effects of exon 21 variants and explain the lack of NDD in relevant patients. Slc12a2 (NKCC1) null mouse model has demonstrated that the transporter plays a role in accumulation of the potassium rich endolymph in the inner ear, with NKCC1 absence causing sensorineural deafness and imbalance. Slc12a2 display cochlear malformations, loss of hair cells and hearing impairment (cited Delpire et al 1999 - PMID: 10369265). The brain phenotype has not been studied extensively, although loss of Slc12a2 has been shown to inhibit neurogenesis (cited: Magalhães and Rivera et al. - PMID: 27582690). Slc12a2 null zebrafish display a collapse of the otic vesicle and reduced endolymph (Abbas and Whitfield, 2009 - PMID: 19633174) relevant to the human hearing disorder. In vitro assessment of NKCC1 ion transporter function in Xenopus laevis, supported the deleterious effect of the identified variants (significant reduction in K+ influx). Using available single cell RNA-seq data the authors further demonstrated that SLC12A2 expressing cells display transcriptomic profiles reflective of active neurogenesis. ► Delpire et al (2016 - PMID: 27900370 - not reviewed in detail) described a 13 y.o. girl harboring a de novo 11-bp deletion in SLC12A2 exon 22. This individual reached developmental milestones on time and had a NORMAL cognitive function. Hearing was seemingly normal. Features included orthostatic intolerance, respiratory weakness, multiple endocrine abnormalities, pancreatic insufficiency and multiorgan failure incl. gut and bladder. Exome in the proband, parents and 3 unaffected sibs suggested SLC12A2 as the only candidate for her phenotype. Functional analyses in Xenopus laevis oocytes suggested that a non functional transporter was expressed and trafficked to the membrane as the wt. Detection of the truncated protein at higher molecular sizes suggested either enhanced dimerization or misfolded aggregate. There was no dominant-negative effect of mutant NKCC1. In patient fibroblasts a reduced total and NKCC1-mediated K+ influx. ► Mutai et al (2020 - PMID: 32294086) report on several individuals from 4 families, harboring variants within exon 21 or - in one case - at it's 3' splice-site (leading to skipping oe this exon at the mRNA level). All subjects were investigated for severe/profound hearing loss (in line with the role of exon 21-included isoforms in cochlea. The variant segregated with hearing impairment in 3 generations of a family while in all other subjects the variant had occured as de novo event. Despite motor delays (e.g. the subject from fam2 could not hold head or sit at the age of 10m / the proband in Fam3 was able to hold his head and walk at 6 and 20 m respectively) behavior and cognition were commented to be within normal range. ----- Biallelic SLC12A2 mutations: ► Anazi et al (2017 - PMID: 29288388) briefly reported on a 3 y.o. boy (17DG0776) with central hypotonia, neonatal respiratory distress, failure to thrive, global DD and microcephaly and a skeletal survey suggestive of osteopenia. After non-diagnostic prior investigations (CMA revealing a 1p duplication classified as VUS, extensive metabolic workup), WES revealed a homozygous SLC12A2 splicing variant [NM_001046.2:c.2617-2A>G]. ► Macnamara et al (2019 - PMID: 30740830) described a 5.5 y.o. male with sensorineural hearing loss, profound delays in all developmental areas among several other features (choanal atresia, failure to thrive, respiratory problems, absent sweat and tear production or salivation, GI abnormalities). Genetic testing for several disorders considered (cystic fibrosis, spinal muscular atrophy, sequencing and del/dup analysis of mtDNA) was normal. CMA revealed paternal uniparental isodisomy for chr. 5 and WGS a homozygous 22kb deletion in SLC12A2. This was followed by confirmation of homozygosity in the proband, heterozygosity of the unaffected father, delineation of breakpoints (chr5:127441491-127471419). mRNA studies in patient fibroblasts confirmed deletion of ex2-7, splicing of ex1 directly to ex8 and introduction of a premature stop codon in ex9. qRT-PCR confirmed that mRNA is likely subjected to NMD (expression ~80% of control). Western blot confirmed absence of the protein in the patient's fibroblasts. Again mouse models are thought to recapitulate the hearing defect but also the deficient saliva production (cited Evans et al 2000 - PMID: 10831596). Again the authors speculate a role of SLC12A2 in brain development based on evidence from murine models (migration, dendritic growth, increse in neuron density through regulation of GABAergic signalling (Young et al 2012 - PMID: 23015452). Hypotheses are also made on a regulatory relationship between NKCC1 and CFTR based on mRNA data from the ko mouse model. ► Stödberg et al (2020 - PMID: 32754646) reported 2 sibs with a complex neurodevelopmental disorder due to compound heterozygosity for a frameshift SLC12A2 variant and a splicing one (NM_001046:c.1431delT and c.2006-1G>A). Both presented hypotonia, neonatal S. aureus parotitis and respiratory problems (incl. apneas). While the older sib died at the age of 22 days, the younger one had persistent respiratory issues incl. a dry respiratory mucosa motivating metabolic, immunology investigations and testing for CF. She displayed microcephaly (OFC -2.5 SD, H was also -3.5SD), severe intellectual disability. MRI was suggestive of white matter and basal ganglia abnormalities. Other features incl. hearing impairment, and lack of tears,saliva and sweat, constipation and intestinal malrotation. There was facial dysmorphism. The variants were the only retained following WGS of the 2 affected sisters, parents and an unaffected brother. The splicing variant was shown to result in skipping of exon 13, while the indel in NMD. Again the authors discuss that the deficient saliva production, impaired hearing and GI problems are recapitulated in the mouse model (several refs provided).; Changed rating: GREEN; Changed publications: 28135719, 32658972, 27900370, 32294086, 29288388, 30740830, 32754646; Changed phenotypes: Kilquist syndrome, deafness, intellectual disability, dysmorphic features, absent salivation, ectodermal dysplasia, constipation, intestinal malrotation, multiple congenital anomalies; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal |

Features included DD (9/10), ID (6/8 of relevant age), microcephaly (7/10), seizures (5/10 - >=3 different variants), structural brain abnormalities (e.g. thin CC in 6/9), highly variable ocular abnormalities (5/10) and dysmorphic features in some (7/10 - nonspecific). All had variable prior non-diagnostic genetic tests (CMA, gene panel, mendeliome, karyotype). WES/WGS revealed LMBRD2 missense variants, in all cases de novo. A single individual had additional variants with weaker evidence of pathogenicity. 5 unique missense SNVs and 2 recurrent ones (NM_001007527:c.367T>C - p.Trp123Arg / c.1448G>A - p.Arg483His) were identified. These occurred in different exons. Variants were not present in gnomAD and all had several in silico predictions in favor of a deleterious effect. There was phenotypic variability among individuals with the same variant (e.g. seizures in 1/3 and microchephaly in 2/3 of those harboring R483H). The gene has a pLI of 0 (although o/e ranges from 0.23 to 0.55), %HI of 15.13 and z-score of 2.27. The authors presume that haploinsufficiency may not apply, and consider a gain-of-function/dominant-negative effect more likely. As the authors comment LMBRD2 (LMBR1 domain containing 2) encodes a membrane bound protein with poorly described function. It is widely expressed across tissues with notable expression in human brain (also in Drosophila, or Xenopus laevis). It displays high interspecies conservation. It has been suggested (Paek et al - PMID: 28388415) that LMBRD2 is a potential regulator of β2 adrenoreceptor signalling through involvement in GPCR signalling. ► Kaplanis et al (2020 - https://doi.org/10.1101/797787) in a dataset of 31058 parent-offspring trios (WES) previously identified 3 individuals with developmental disorder, harboring c.1448G>A - p.Arg483His.

The current review is based only on this reference. The authors provide clinical details on 6 affected individuals from 5 families. Features included postnatal growth delay, DD and ID (6/6 - also evident for those without formal IQ assesment), seizures (3/6 from 2 families), prominent forehead with presence of other facial features and variable head circumference (5th to >97th %le), ocular anomalies (5/6 - strabismus/nystagmus/Axenfeld-Rieger), cardiac (3/6 - ASD/Fallot) and genitourinary anomalies (3/6). In the first of these families (Armfield et al 1999 - PMID: 10398235), linkage analysis followed by additional studies (Sanger, NGS of 718 genes on chrX, X-exome NGS - several refs provided) allowed the identification of a FAM50A variant. Variants in other families were identified by singleton (1 fam) or trio-ES (3 fam). In affected individuals from 3 families, the variant had occurred de novo. Carrier females in the other families were unaffected (based on pedigrees and/or the original publication). XCI was rather biased in most obligate carrier females from the 1st family (although this ranged from 95:5 to 60:40). Missense variants were reported in all affected subjects incl. Trp206Gly, Asp255Gly, Asp255Asn (dn), Glu254Gly (dn), Arg273Trp (dn) (NM_004699.3). Previous studies have demonstrated that FAM50A has ubiquitous expression in human fetal and adult tissues (incl. brain in fetal ones). Immunostaining suggests a nuclear localization for the protein (NIH/3T3 cells). Comparison of protein levels in LCLs from affected males and controls did not demonstrate significant differences. Protein localization for 3 variants (transfection of COS-7 cells) was shown to be similar to wt. Complementation studies in zebrafish provided evidence that the identified variants confer partial loss of function (rescue of the morpholino phenotype with co-injection of wt but not mt mRNA). The zebrafish ko model seemed to recapitulate the abnormal development of cephalic structures and was indicative of diminished/defective neurogenesis. Transcriptional dysregulation was demonstrated in zebrafish (altered levels and mis-splicing). Upregulation of spliceosome effectors was demonstrated in ko zebrafish. Similarly, mRNA expression and splicing defects were demonstrated in LCLs from affected individuals. FAM50A pulldown followed by mass spectrometry in transfected HEK293T cells demonstrated enrichment of binding proteins involved in RNA processing and co-immunoprecipitation assays (transfected U-87 cells) suggested that FAM50A interacts with spliceosome U5 and C-complex proteins. Overall aberrant spliceosome C-complex function is suggested as the underlying pathogenetic mechanism. Several other neurodevelopmental syndromes are caused by variants in genes encoding C-complex affiliated proteins (incl. EFTUD2, EIF4A3, THOC2, etc.). Sources: Literature |

The phenotype corresponded to a neurodevelopmental disorder and - as the authors comment - consistently included DD, ID , behavioral problems. Postnatal growth delay was observed in approximately half. Hypertelorism, ptosis, downslant of palpebral fissures, wide nasal bridge as low-set/posteriorly rotated ears were among the facial features observed (each in 3 or more subjects within this cohort). Together with short/webbed neck and abnormalities of skin (lentigines / CAL spots) and growth delay these led to clinical suspicion of Noonan s. or disorder of the same pathway in some. Congenital heart defects (ASD, mitral valve insufficiency, though not cardiomyopathy) occurred in 4/7. Bleeding diathesis and lymphedema were reported only once. MAPK1 encodes the mitogen-activated protein kinase 1 (also known as ERK2) a serine/threonine kinase of the RAS-RAF-MEK-(MAPK/)ERK pathway. MAPK1 de novo variants were identified in all individuals following trio exome sequencing (and extensive previous genetic investigations which were non-diagnostic). The distribution of variants, as well as in silico/vitro/vivo studies suggest a GoF effect (boosted signal through the MAPK cascade. MAPK signaling also upregulated in Noonan syndrome).

DD/ID (borderline intellectual functioning to severe ID) was a feature in all. Variable other findings included brain malformations (CCA) and microcephaly. 3 missense variants and a 4-bp insertion were identified, in 3 cases as de novo events while in a single subject the variant was inherited from the father who was also affected. The authors provide evidence for a role of KIF21B in the regulation of processes involved in cortical development and deleterious effect of the missense variants impeding neuronal migration and kinesin autoinhibition. Phenotypes specific to variants (e.g. CCA or microcephaly) were recapitulated in animal models. Missense variants are thought to exert a gain-of-function effect. As commented on, the 4-bp duplication (/frameshift) variant might not be pathogenic. In blood sample from the respective individual, RT-qPCR analysis suggested that haploinsufficiency (NMD) applies. Although Kif21b haploinsufficiency in mice was shown to lead to impaired neuronal positioning, the gene might partially tolerate LoF variants as also suggested by 28 such variants in gnomAD. Homozygous Kif21b ko mice display severe morphological abnormalities, partial loss of commissural fibers, cognitive deficits and altered synaptic transmission (several refs to previous studies provided by the authors).

Features included cognitive impairment (mild ID in one case, regression at the age of 12y in another, hypotonia and delayed milestones in a third aged 8m), seizures (3/3 - variable age of onset) and/or gingival overgrowth (2/3 - prior to initiation of AEDs). Other findings included behavioral abnormalities, mandibular anomalies, abnormal brain imaging and ophthalmologic or (rarely) audiometric evaluations. All were born to non-consanguineous couples and additional investigations were performed in some. Variants were identified by WES or trio WGS, with Sanger confirmation/compatible segregation analyses. In line with the pLoF variants, mRNA studies in fibroblasts from 2 unrelated affected individuals demonstrated significantly reduced (~80-90%) TBC1C2D mRNA levels compared to controls, restored following cycloheximide treatment. Protein was absent in patient fibroblasts. TBC-domain containing GTPase activating proteins are known as key regulators of RAB GTPase activity. TBC1D2B was shown to colocalize with RAB5-positive endocytic vesicles. CRISPR/Cas9-mediated ko of TBC1D2B in HeLa cells suggested a role in EGF receptor endocytosis and decreased cell viability of TBC1D2B-deficient HeLa cells upon serum deprivation. Genes encoding other TBC domain-containg GTPase-activating proteins, e.g. TBC1D7 and TBC1D20, TBC1D24 are associated with recessive neurodevelopmental disorders (with ID and/or seizures) and the pathophysiological defect in TBC1D2B-related disorder (deficit in vesicle trafficking and/or cell survival) is proposed to be similar to that of TBC1D24.

Mendeliome v0.2759 | TNRC6B | Zornitza Stark edited their review of gene: TNRC6B: Added comment: 17 unrelated individuals with heterozygous TNRC6B variants reported. Features included hypotonia (10/17), DD/ID (17/17 - ID was not universal: average IQ of 12 individuals was 73 (range : 50-113) with 4 having below 70), ADHD (11/17), ASD or autistic traits (8/17 and 5/17). Some/few presented with abnormal OFC (micro- / macrocephaly in 3/17 and 2/17), abnormal vision or hearing, variable other congenital anomalies, echocardiographic, GI or renal abnormalities, etc. Epilepsy was reported in 1/17. There was no recognisable gestalt.Detected variants included 14 pLoF, 1 missense SNV and 2 intragenic deletions. Variants had occurred as de novo events in 10/13 subjects for whom testing of both parents was possible. 3/13 subjects had inherited the variant from a parent with milder phenotype. Based on the type of variants identified, the pLI score of 1 in gnomAD and the HI index of 5.61%, the authors suggest haploinsufficiency as the most likely mechanism. Individuals with de novo TNRC6B variants have also been reported in larger cohorts (e.g. DDD study - PMID: 28135719, Iossifov et al - PMID: 25363768, Lelieveld et al - PMID: 27479843, Jónsson et al - PMID: 28959963).

Chern Lim changed review comment from: No patients reported with ZNF592 variant that is clearly disease causing. A 2010 paper published a biallelic missense variant segregating in one family with non-progressive, autosomal recessive, congenital cerebellar ataxia; however functional data not strongly supportive of pathogenicity (PMID: 20531441). Same authors later identified a homozygous WDR73 variant in that family which explains the phenotype (PMID: 26123727).; to: No patients reported with ZNF592 variant that is clearly disease causing.

The mutations segregated with the disorder in all families. In vitro functional cellular expression studies showed that protein levels of the SVBP mutants were barely detectable, suggesting instability, and that the mutant proteins had lost VASH/SVBP catalytic detyrosination activity toward tubulin. Knockdown of about 50% Svbp expression using shRNA in rat hippocampal neurons impaired the formation of excitatory synapses compared to controls. Sources: Literature |

Western blot analysis of proteins overexpressed in the Drosophila fat body showed strongly reduced levels of the SCAMP p.Gly302Trp protein compared with the wild-type protein, indicating that the mutant either reduced expression or increased turnover of the protein. The expression of the fly homologue of the human SCAMP5 p.Gly180Trp mutation caused similar eye and neuronal phenotypes as the expression of SCAMP RNAi, suggesting a dominant-negative effect.
