Added comment: This study reports 9 unrelated individuals with de novo heterozygous variants in ATXN7L3 identified through WES testing and GeneMatcher. Core clinical features included: global motor and language developmental delay, hypotonia, and dysmorphic features (hypertelorism, epicanthal folds, blepharoptosis, small nose, small mouth, and low-set posteriorly rotated ears). Variable features included: feeding difficulties, seizures, mild periventricular leukomalacia, and structural cardiac abnormalities.

A recurrent nonsense variant [p.(Arg114Ter)] was found in 5/9 individuals. The other variants were 1 frameshift [p.(Ser112LysfsTer12)] and 3 missense variants [p.(Ile71Thr), p.(Ser92Arg), and p.(Leu106Pro)]. They investigated the effects of the recurrent nonsense variant [p.(Arg114Ter)] in fibroblasts of an affected individual. ATXN7L3 protein levels were reduced, and deubiquitylation was impaired (as indicated by an increase in histone H2Bub1 levels). This is consistent with the previous observation of increased H2Bub1 levels in Atxn7l3-null mouse embryos, which have developmental delay and embryonic lethality.

Pathogenic variants in deubiquitinating enzymes (DUBs) have been implicated in neurodevelopmental disorders (ND) and congenital abnormalities. ATXN7L3 is a component of the DUB module of the SAGA complex, and two other related DUB modules, and serves as an obligate adaptor protein of 3 ubiquitin-specific proteases (USP22, USP27X or USP51).

SEL1L protein is involved in the SEL1L-HRD1 endoplasmic reticulum (ER)-associated degradation.

Report two biallelic missense variants in SEL1L in six children from three independent families presenting with developmental delay, intellectual disability, microcephaly, facial dysmorphisms, hypotonia and/or ataxia (termed ERAD-associated neurodevelopment disorder with onset in infancy (ENDI). The variants were hypomorphic and impaired ERAD function.

Identified by WES. Parents heterozygous and asymptomatic. P.(Gly585Asp) in Patient 1, p.(Met528Arg) in Patients 2 and 3 (siblings).

All variants cause substrate accumulation. The extent of substrate accumulation in knockin cells was modest compared to those in knockout cells, pointing to a hypomorphic nature.

They also had a variant in HRD1.



Weis paper PMID: 37943617

Third variant p.(Cys141Tyr), biallelic, causing premature death in five patients from a consanguineous family with early-onset neurodevelopmental disorders and agammaglobulinaemia due to severe SEL1L-HRD1 ERAD dysfunction.

This variant appears to have a more severe outcome, exhibiting B cell depletion and agammaglobulinaemia, causing the most severe dysfunction among all of the variants described by this group so far. They postulate that functionality of SEL1L-HRD1 ERAD is inversely correlated with disease severity in humans.

Their symptoms were dev delay, neurological disorder and agammaglobulinaemia in childhood. Along with severe axial hypotonia, short stature and microcephaly.

“Not a complete loss-of-function variant”.

Mendeliome v1.1156 APOO Zornitza Stark edited their review of gene: APOO: Added comment: PMID: 37649161
1 family, 2 individuals (male & female) with same NMD variant c.532G>T (p.E178*), maternally inherited (mother unaffected).

Both died before 18 months of age with partial agenesis of the corpus callosum, bilateral congenital cataract, hypothyroidism, and severe immune deficiencies.
Other phenotypes included partial syndactyly of the 2nd and 3rd toes, wrinkled palm, and sole skin.

Functional studies included site directed mutagenesis. This mutation resulted in a highly unstable and degradation
prone MIC26 protein, yet the remaining minute amounts of mutant MIC26 correctly localized to mitochondria and
interacted physically with other MICOS subunits. MIC26 KO cells expressing MIC26 harboring the respective APOO/MIC26 mutation showed mitochondria with perturbed cristae architecture and fragmented morphology resembling MIC26 KO cells.; Changed publications: 37649161; Changed phenotypes: Mitochondrial disease, MONDO:0044970, APOO-related, Developmental delay, Lactic acidosis, Muscle weakness, Hypotonia, Repetitive infections, Cognitive impairment, Autistic behaviour

Cohort of patients with an MRI based diagnosis of megalencephalic leukoencephalopathy with subcortical cysts (MLC). Missense variant in AQP4 seen homozygous in 2 siblings and het in the parents. Patients had macrocephaly, developmental delay, hypotonia, epilepsy, and cognitive deficit.

Western blots on generated MDCK cell lines showed no detectable expression of AQP4 protein from the cells with the patients variant. Immunofluorescence also showed no membrane expression. Overexpression studies in HEK293T cells showed WT was seen as mainly monomers or dimers where as variant protein formed large aggregates- likely due to the saturation of protein degradation pathways because of the overexpression.

Added comment: ESHG 2023:
3 unrelated cases with CdLS (1 x TOP with MCA, 1 x death @20mths, 1 x living child)
Features suggestive of CdLS - DD, microcephaly, CHD, dysmorphism, visual/hearing impairment.

WES identified recurrent de novo variant (p.Ser470Phe) in DCAF15 gene. This mediates ubiquitination and degradation of target proteins, and interacts with cohesin complex members (SMC1/SMC3).

Protein analysis from individuals showed increased accumulation of ubiquitination-modified proteins and SM3 (GOF mechanism). EpiSign analysis showed same DNA methylation pattern as other CdLS cases/genes. Zebrafish model showed reduced body length, reduced head size, reduced oligodendrocytes, heart defect, aberrant motor neurons, and abnormal response to visual/auditory stimuli.

In 10/11 families the variant occurred de novo in a single affected proband. In one family with 2 affected siblings, the variant was present in the siblings but absent in the unaffected parent likely due to gonadal mosaicism.

Clinical features included:
- Cutis aplasia congenital of the scalp (10/11)
- Tooth enamel hypoplasia and discolouration (8/9)
- Multiple other ectodermal features also noted e.g. small brittle nails, hypotrichosis/hypertrichosis, lichen sclerosis

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.

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.

Added comment: p.(Arg192Ter), a truncating variant that results in loss of 6 amino acids, was detected in two families (one Polish and one Korean) with hearing loss. 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.

Added comment: Semino et al (2021 - PMID: 34157790) provide clinical details on 3 unrelated individuals with de novo SYNCRIP variants and provide a review of 5 additional subjects previously identified within large cohorts in the literature and databases.

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.

SYNCRIP (also known as HNRNPQ) encodes synaptotagmin‐binding cytoplasmic RNA‐interacting protein. 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.

Mendeliome v0.8011 ADA2 Zornitza Stark commented on gene: ADA2: Vasculitis, autoinflammation, immunodeficiency, and haematologic defects syndrome (VAIHS) is an autosomal recessive multisystem disorder with onset in childhood. 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. At least 10 unrelated families reported, the p.Gly47Arg variant is a common founder variant in the Jewish population.

Added comment: PMID: 31960911 - Gravesteijn et al 2020 - describe a family with a unique cysteine-altering NOTCH3 variant in exon 9 in 5 individuals, which is predicted to cause natural exon 9 skipping. This mimics the therapeutic NOTCH3 cysteine correction approach and allows the effect of cysteine corrective exon skipping on NOTCH3 protein aggregation and disease severity in humans to be studied. In this family the CADASIL phenotype was mild.

Mendeliome v0.4091 TRPM7 Eleanor Williams commented on gene: TRPM7: PMID: 31423533 - Cartwright et al 2020 - functional studies on four heterozygous nonsynonymous variants that were observed in TRPM7 in four individual cases of unexplained still birth which were screened for variants in 35 candidate genes in PMID: 29874177 (Munroe et al 2018). TRPM7 is a ubiquitously expressed ion channel known to regulate cardiac development and repolarization in mice. They found two variants in TRPM7, p.G179V and p.T860M, reduce ion channel current expression, which in the case of p.T860M is likely due to rapid degradation mediated by the proteasome. In addition, the p.R494Q TRPM7 variant significantly increases TRPM7 ion channel current, in a cell-type specific manner. They believe that TRPM7 may play a key role in ensuring correct cardiac development of the fetus.

Added comment: Homozygous and compound heterozygous variants (missense, nonsense and frameshift) found in 8 Japanese patients from unrelated families with unexplained galactosaemia. (No variants in GALT, GALK1, and GALE). This is therefore type IV galactosaemia.
In vitro expression analysis and enzyme activity assay of the patients’ peripheral blood mononuclear cells showed total lack of or compromised expression of GALM protein. Loss-of-function mechanism. One homozygote for one of these variants p.(Gly142Arg) in gnomAD (African population). (Wada, Y. et al 2019; PMID: 30451973)
In vitro expression assay and an enzyme activity assay of 67 GALM variants, taken from ExAc database (missense, nonsense, frameshift and splice). 30 variants concluded to be pathogenic due to no protein expression or faint expression. 5 variants with mildly lower levels were determined as likely pathogenic. All concluded to be loss-of-function mechanism. Incidence of galactosaemia by GALM deficiency is comparable to that of other galactosaemias. Carrier frequency and incidence was estimated for different populations. (Iwasawa, S. et al. (2019); PMID: 30910422)
