Added comment: Total of three families, but two share a founder variant, and there are some disparities between the clinical presentations reported in the two publications. Rating Amber as additional cases required to delineate the genotype-phenotype relationship. PMID: 30120216 (2018) - Two unrelated probands with an identical homozygous missense (c.109G>T, p.Asp37Tyr) variant in TRAPPC2L. Both individuals presented neurodevelopmental delay, febrile illness-induced encephalopathy, and episodic rhabdomyolysis, followed by developmental arrest, seizures and tetraplegia. The variant segregated with the phenotype in each family, and haplotype analysis suggested a founder effect. The mutant protein was expressed in patient fibroblasts, but displayed membrane trafficking delays. Studies in yeast showed that the variant impaired interaction with TRAPPC10, and increased levels of the active RAB11. PMID: 32843486 (2020) - In an Ashkenazi Jewish family with three affected sibs with GDD/ID, WGS revealed a segregating homozygous missense variant (c.5G>C, p.Ala2Gly) in the TRAPPC2L gene. No seizures, brain MRI abnormalities, or illness provoked regression were documented in this family. Comparable to the previous study, the variant resulted in delayed ER-to-Golgi trafficking and elevated levels of active RAB11. Studies using yeast and in vitro binding, showed that the variant disrupted interaction with another core TRAPP protein, TRAPPC6a.

Review for gene: CTNND1 was set to AMBER
Added comment: 4 individuals from 3 unrelated families with blepharocheilodontic syndrome and mutations in the CTNND1 gene reported originally in PMID 28301459. All had eyelid anomalies, including ectropion of the lower lids, euryblepharon, lagophthalmia, and distichiasis. In addition, all 4 showed typical facial dysmorphism with hypertelorism, flat face, and high forehead, and all had conical teeth and tooth agenesis. Three had cleft lip and palate, 3 had hair anomalies, and 1 had hypothyroidism due to hypoplasia or aplasia of the thyroid gland. None of the patients exhibited anal atresia or neural tube defects.

PMID: 32196547 - Alharatani et al 2020 - report an expanded phenotype for CTNND1 patients. They report 13 individuals from nine families with novel protein-truncating variants in CTNND1 identified by WES. The mutations were not previously described in blepharocheilodontic (BCD), orofacial cleft cases nor in gnomAD. 8 patients had de novo variants, 2 inherited from affected parents, 2 participants inherited a variant from a parent with a mild phenotype. 8/13 patients showed cleft palate. Additional phenotypic features seen include mild limb phenotypes (9/13), cardiovascular anomalies (6/13) and Developmental delay and other neurodevelopmental problems (8/13).

This more recent publication suggests a broader phenotype associated with CTNND1 variants including dev delay, ADHD/ASD, behavioural issues. Unclear from description whether significant ID present.

Added comment: You may consider inclusion with green (13 individuals with dn missense SNVs overall, overlapping features for 10 with available phenotype / a recurring variant has been identified in 2 different studies) or amber rating (role of the gene not known, no variant studies, animal model probably not available).

► Malhotra et al (2020 - PMID: 32820033) report on 10 unrelated individuals with de novo missense LMBRD2 variants.

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. These individuals (1 from the DDD study, and 2 GeneDx patients) appear in Decipher. [ https://decipher.sanger.ac.uk/ddd/research-variant/40e17c78cc9655a6721006fc1e0c98db/overview ]. The preprint by Kaplanis et al is cited by Malhotra et al, with Arg483His reported in 6 patients overall in both studies.

Added comment: Knuutinen et al (2020 - PMID: 32779182) report on 2 individuals from 2 consanguineous families, homozygous for TAF1C missense variants.

Both presented with an early onset neurological phenotype with severe global DD, ID (2/2 - moderate and profound), spasticity (2/2), ophthalmic findings (strabismus 2/2, nystagmus 1/2). Epilepsy, abnormal brain MRI (cerebral and cerebellar atrophy and white matter hyperintensities) as well and additional findings were reported in one (always the same individual).

Following a normal CMA, exome in the first case revealed a homozygous missense SNV (NM_005679.3:c.1165C>T / p.Arg389Cys) supported by in silico predictions. mRNA and protein levels were substantially reduced in fibroblasts from this subject. Only the patient and parents were tested for the variant but not 3 unaffected sibs (fig1).

The second individual was homozygous for another missense variant (p.Arg405Cys) also supported by in silico predictions. The girl was the single affected person within the family with an unaffected sib and parents heterozygous for the variant. Several other unaffected relatives in the extended pedigree were either carriers for this variant or homozygous for the wt allele.

TAF1C encodes the TATA-box binding protein associated factor (TAF) RNA polymerase I subunit.

RNA polymerase I (Pol I) transcribes genes to produce rRNA. For Pol I to initiate transcription, two transcription factors are required : UBF (upstream binding factor encoded by UBTF) and SL1 (selectivity factor 1). The latter is formed by TBP (TATA-binding protein) and 3 Pol I-specific TBP-associated factors (TAFs).

A recurrent de novo missense variant in UBTF (encoding the other Pol I transcription factor) causes a disorder with highly similar features. The specific variant acts through a gain-of-function mechanism (and not by LoF which appears to apply for TAF1C based on expression data).

The authors hypothesize that altered Pol I activity and resulting ribosomal stress could cause the microcephaly and leukodystrophy (both reported in 1 - the same - individual).

As a result, TAF1C may be considered for inclusion in the ID panel with amber rating pending further evidence.

Added comment: Lee et al (2020 - PMID: 32703943) provide evidence that Armfield X-Linked intellectual disability syndrome is caused by monoallelic FAM50A pathogenic variants. 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.).

Please consider inclusion in the ID panel with green rating and epilepsy panel with amber (seizures in individuals from 2 families).

Johnstone et al (2020 - PMID: 32588908) describe the phenotype of 7 children (from 6 families) with biallelic PIGQ pathogenic variants. The authors also review the phenotype of 3 subjects previously reported in the literature (by Martin et al, Alazami et al, Starr et al - respective PMIDs: 24463883, 25558065, 31148362).

Affected individuals displayed severe to profound global DD/ID and seizures with onset in the first year of life. There were variable other features incl. - among others - genitourinary, cardiac, skeletal, ophthalmological anomalies, gastrointestinal issues. Within the cohort there was significant morbidity/mortality.

PIGQ encodes phosphatidylinositol glycan anchor biosynthesis class Q protein, playing a role (early) in the biosynthesis of the GPI-anchor. Several genes in the GPI biosynthesis pathway cause multi-system disease with DD/ID and seizures. Flow cytometry has been used in individuals with PIGQ-related disorder. Serum ALP was elevated in some (4) although - as the authors comment - elevations are more typical in disorders affecting later steps of GPI biosynthesis.

More than 10 variants have been reported to date (missense / pLoF).

Overall PIGQ can be considered for green rating in both ID and epilepsy gene panels.

Intellectual disability syndromic and non-syndromic v0.2805 NARS Konstantinos Varvagiannis changed review comment from: [Please note that HGNC Approved Gene Symbol for this gene is NARS1]

Manole et al (2020 - PMID: 32738225) provide evidence that both biallelic and monoallelic (de novo) pathogenic NARS1 variants cause a neurodevelopmental disorder. In total 32 individuals from 21 families are reported, with biallelic variants identified in individuals from 13 families and de novo in 8 families.

Similar features were reported for AR/AD occurrences of the disorder and included of microcephaly (90% - most often primary), epilepsy (23/32 or 74% - variable semiology incl. partial/myoclonic/generalized tonic-clonic seizures), DD and ID (as a universal feature), abnormal tone in several (hypotonia/spasticity), ataxia, demyelinating peripheral neuropathy (in 3 or more for each inheritance mode - or a total of 25%). Some individuals had dysmorphic features.

NARS1 encodes an aminoacyl-tRNA synthetase (ARS) [asparaginyl-tRNA synthetase 1]. Aminoacyl-tRNA synthetases constitute a family of enzymes catalyzing attachment of amino-acids to their cognate tRNAs. As the authors comment, mutations in genes encoding several other ARSs result in neurological disorders ranging from peripheral neuropathy to severe multi-systemic NDD. Dominant, recessive or both modes for inheritance for mutations in the same gene (e.g. AARS1, YARS1, MARS1, etc) have been reported.

Some variants were recurrent, e.g. the c.1600C>T / p.Arg534* which occurred in 6 families as a de novo event or c.1633C>T p.Arg545Cys (homozygous in 6 families). 3 different variants were reported to have occured de novo (c.965G>T - p.Arg322Leu, c.1525G>A - p.Gly509Ser, p.Arg534*) with several other variants identified in hmz/compound htz individuals. A single SNV (c.1067A>C - p.Asp356Ala) was suggested to be acting as modifier and pathogenic only when in trans with a severe variant. [NM_004539.4 used as RefSeq for all].

The authors provide several lines of evidence for a partial loss-of-function effect (e.g. reduction in mRNA expression, enzyme levels and activity in fibroblasts or iNPCs) underlying pathogenicity of the variants identified in individuals with biallelic variants. A gain-of-function (dominant-negative) effect is proposed for de novo variants (such effect also demonstrated for the p.Arg534* in a zebrafish model).

As also Manole et al suggest, NARS1 can be considered for inclusion in gene panels for DD/ID, epilepsy and/or demyelinating neuropathy.

Biallelic variants:

- Kambouris et al. (2014 - PMID: 24907849) described 2 brothers with severe DD and ID, born to first cousin parents. Homozygosity mapping, following other non-diagnostic investigations (incl. aCGH), revealed 4 major homozygosity intervals. Exome sequencing in one identified 5 variants within these intervals, ZNF407 (c.5054C>G, p.Ser1685Trp) being the best candidate, supported also by segregation studies. The authors commented that zinc finger proteins act as transcriptional regulators, with mutations in genes encoding for other zinc finger proteins interfering with normal brain development.

- Zahra et al. (2020 - PMID: 32737394) report on 7 affected individuals (from 3 families) homozygous or compound heterozygous for ZNF407 variants. Features included hypotonia, DD and ID (in all) and variable occurrence of short stature (6/6), microcephaly (in at least 5), behavioural, visual problems and deafness. Linkage analysis in the first family revealed a 4.4 Mb shared homozygosity region and exome (30x) revealed a 3-bp duplication, confirmed by Sanger sequencing and segregating with the disease (NM_001146189:c.2814_2816dup, p.Val939dup). Affected subjects from the 2 other families were each found to be homozygous (c.2405G>T) or compound heterozygous (c.2884C>G, c.3642G>C) for other variants. Segregation was compatible in all families. Other studies were not performed. The authors comment than only the 3-bp duplication fullfilled ACMG criteria for classification as LP, the other variants being all formally classified as VUS (also due to in silico predictions predicting a LB effect). In addition, while several features such as DD/ID and short stature appeared to be frequent among all patients reported, Zahra et all comment that there was partial clinical overlap with the sibs described by Kambouris et al (additional variants?).


Monoallelic disruption of ZNF407:

- Ren et al (2013 - PMID: 23195952) described an 8 y.o. boy with ID and ASD. The boy was found to harbor a de novo translocation between chromosomes 3 and 18 [46,XY,t(3;18)(p13;q22.3)]. Array CGH did not reveal any P/LP CNV. Delineation of the breakpoints (FISH, long-range PCR) revealed that the chr18 breakpoint disrupted intron 3 of ZNF407 (isoform 1) with the other breakpoint within a gene-free region of exon 3. There was a loss of 4-8 nt in chr18 and 2-6 in chr3. Sequencing of ZNF407 did not reveal additional variants. RNA isolation in blood followed by RT-PCR studied expression of all 3 ZNF407 isoforms (the intronic region being shared by isoforms 1 and 2). Expression of isoform 1 was shown to be significantly reduced compared to controls. Isoform 2 was undetectable (in blood) while isoform 3 expression was similar to controls. Sequencing of 105 additional patients with similar clinical presentation (ID & ASD) revealed 2 further individuals with de novo missense variants.

- Based on the discussion by Kambouris et al (PMID: 24907849 - cited literature not here reviewed) ZNF407 may be deleted in patients with congenital aural atresia due to deletion of a critical region of 18q22.3 (though TSHZ1 is responsible for this phenotype) or 18q- although such deletions span several other genes (cited PMID: 16639285).

Added comment: Motta et al (2020 - PMID: 32721402) report on 7 unrelated individuals harboring de novo missense MAPK1 pathogenic variants.

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).

The authors comment that screening of 267 additional individuals with suspected RASopathy (without mutations in previously implicated genes) did not reveal other MAPK1 variants.

Overall this gene can be considered for inclusion in the ID panel with green rating.

Biallelic pathogenic LARS1 variants cause Infantile liver failure syndrome 1, MIM# 615438.

Lenz et al (2020 - PMID: 32699352) review the phenotype of 25 affected individuals from 15 families.

Seizures occurred in 19/24 and were commonly associated with infections. Encephalopathic episodes (in 13 patients) accompanied by seizures up to status epilepticus occurred independently of hepatic decompensation.

In addition 22/24 presented with neurodevelopmental delay. The authors comment that cognitive impairment was present in 13/17 individuals (mild-severe) whereas most presented with learning disabilities.

These patients will most likely investigated for their liver disease (although presentation was highly variable and/or very mild in few).

The gene encodes a cytoplasmic amino-acyl tRNA synthetase (ARS) with neurologic manifestations observed in almost all patients (and seizures / DD and ID common to other disorders due to mutations in other genes encoding for ARSs).

Please note that the HGNC approved symbol for this gene is LARS1.

Added comment: The current review is based on a recent report by Sacoto et al (2020 - https://doi.org/10.1016/j.ajhg.2020.06.013).

While several previous studies focused on the phenotype of axonal motor and senory neuropathy in individuals with heterozygous MORC2 pathogenic variants (Charcot-Marie-Tooth disease, axonal, type 2Z, MIM #616688) some of them presented among others with hypotonia, muscle weakness, intellectual disability, microcephaly or hearing loss [refs provided by Sacoto et al - learning disabilities (in some patients) also listed in OMIM's clinical synopsis].

Sacoto et al present a cohort of 20 individuals having genetic testing for developmental delay or growth failure (with a single one for a diagnosis of sensorimotor neuropathy).

Overlapping features included DD, ID (18/20 - mild to severe), short stature (18/20), microcephaly (15/20) and variable craniofacial dysmorphisms. The authors comment that features suggestive of neuropathy (weakness, hyporeflexia, abnormal EMG/NCS) were frequent but not the predominant complaint. EMG/NCS abnormalities were abnormal in 6 out of 10 subjects investigated in this cohort. Other findings included brain MRI abnormalities (12/18 - in 5/18 Leigh-like lesions), hearing loss (11/19) and pigmentary retinopathy in few (5).

Affected subjects were found to harbor in all cases missense variants in the ATPase module of MORC2 [residues 1 to 494 - NM_001303256.1 - the module consists of an ATPase domain (aa 1-265), a transducer S5-like domain (266-494) and a coiled-coiled domain (CC1 - aa 282-361)].

Variants had occured mostly as de novo events although inheritance from a similarly affected parent was also reported.

Some of them were recurring within this cohort and/or the literature eg. c.79G>A/p.Glu27Lys (x5), c.260C>T/p.Ser87Leu (x2), c.394C>T/p.Arg132Cys (4x), c.1164C>G/p.Ser388Arg (x2), c.1181A>G/p.Tyr394Cys (x3).

MORC2 encodes an ATPase involved in chromatin remodeling, DNA repair and transcriptional regulation. Chromatin remodeling and epigenetic silencing by MORC2 is mediated by the HUSH (Human Silencing Hub) complex. Functional studies (MORC2-knockout HeLa cells harboring a HUSH-sensitive GFP reporter were transduced with wt or mt MORC2 followed by measurement of reporter repression) supported the deleterious effect of most variants known at the time (hyperactivation of HUSH-mediating silencing, in line with previous observations).

Overall this gene can be considered for inclusion in the ID panel with green rating. Also other gene panels (e.g. for short stature, microcephaly, hearing loss, pigmentary retinopathy, etc) if it meets the respective criteria for inclusion.

Added comment: Asselin et al (2020 - PMID: 32415109) report on 4 individuals with KIF21B pathogenic variants. 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).

Added comment: Biallelic PAX1 pathogenic variants cause Otofaciocervical syndrome 2 (OMIM 615560).

Brief review of the literature suggests 3 relevant publications to date (04-07-2020).

2 individuals with DD and ID have been reported (Patil et al, 2018 - PMID: 29681087 and Pohl et al, 2013 - PMID: 23851939). Other subjects reported were only evaluated as newborns(mostly)/infants [Paganini et al, 2017 - PMID: 28657137, Patil et al, 2018 - PMID: 29681087].

While the first report by Pohl et al identified a homozygous missense variant supported by functional studies [NM_006192.5:c.497G>T - p.(Gly166Val)] subsequent ones identified homozygosity for pLoF mutations [Patil et al: NM_006192.4:c.1173_1174insGCCCG / Paganini et al: NM_006192:c.1104C>A - p.(Cys368*)].

As discussed by Pohl et al:

PAX1 encodes a transcription factor with critical role in pattern formation during embryogenesis. Study of the mouse Gly157Val (equivalent to human Gly166Val) Pax1 variant suggested reduced binding affinity (reduced transactivation of a regulatory sequence of the Nkx3-2 promoter) and hypofunctional nature of this variant.

Mouse models seem to recapitulate features of the disorder (skeletal, immunodeficiency) while the role of Pax1 in hearing process was thought to be supported by early expression (P6) in mouse cochlea.

Overall this gene can be considered for inclusion in the ID panel with amber/green rating.

Added comment: 6 unrelated individuals with Leukodystrophy, hypomyelinating, 16 (MIM #617964) due to a recurrent TMEM106B variant have been reported to date in the literature (Simons et al 2017 - PMID: 29186371, Yan et al 2018 - PMID: 29444210, Ikemoto et al 2020 - PMID: 32595021).

While a 3 y.o. female described by Yan et al had DD (eg sitting at 9m, walking at 25m) with normal cognitive functioning, and a 38 y.o. female had borderline intellectual functioning (IQ 76), 4 affected individuals had ID. Among them, a 19 y.o. male with severe ID was also found to harbor a second de novo possibly damaging USP7 variant. Seizures have been reported in 2 unrelated subjects. [Clinical features are also summarized in table 1 - Ikemoto et al].

All harbored NM_001134232.2(TMEM106B):c.754G>A (p.Asp252Asn) which in almost all cases occurred as a de novo event. In a single case this variant was inherited from a mosaic parent with mild DD in infancy but normal cognition (reported by Simons et al).

As discussed by Ito et al (2018 - PMID: 30643851) the encoded protein is a structural component of the lysosomal membrane, playing a role on lysosome acidification. Acidity of the lysosome mediates multiple aspects of lysosomal function. Ito et al, using patient-derived fibroblasts assessed mRNA and protein levels. These were unaltered compared with controls. While TMEM106B had been previously shown to affect lysosome number, morphology and acidification, Ito et al demonstrated increased number of lysosomes in patient cells as well as impaired acidification compared to controls. As commented lysosomes are required for generation of myelin.

Recurrence of this missense variant, the presence of pLoF TMEM106B variants in gnomAD as well as the phenotypically normal Tmem106b null mice suggest that this variant may have a gain-of-function or dominant negative effect.

Genes for other forms of hypomyelinating lipodystrophy (incl. PLP1) have green rating in the ID panel.

Overall TMEM106B can be considered for the ID panel with green rating and the epilepsy panel with amber rating.

Added comment: Harms et al (2020 - PMID: 32623794) report on 3 unrelated individuals with biallelic pLoF TBC1D2B variants.

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.

Overall this gene can be considered for inclusion with amber/green rating in the ID panel and green in epilepsy panel.

Added comment: Van Bergen et al (2020 - PMID: 32639540) report on 3 individuals from 2 families, harboring biallelic EXOC2 mutations.

Clinical presentation included DD, ID (severe in 2 subjects from fam1, borderline intellectual functioning in fam2), dysmorphic features and brain abnormalities. Cerebellar anomalies were common to all with a molar tooth sign observed in one (1/3). Other findings limited to subjects from one family included acquired microcephaly, congenital contractures, spastic quadriplegia (each observed 2/3).

Previous investigations were in all cases non-diagnostic. WES identified biallelic EXOC2 mutations in all affected individuals.

EXOC2 encodes an exocyst subunit. The latter is an octameric complex, component of the membrane transport machinery, required for tethering and fusion of vesicles at the plasma membrane. As discussed ,vesicle transport is important for the development of brain and the function of neurons and glia. Exocyst function is also important for delivery of Arl13b to the primary cilium (biallelic ARL13B mutations cause Joubert syndrome 8) and ciliogenesis.

Affected subjects from a broader consanguineous family (fam1) were homozygous for a truncating variant. Fibroblast studies revealed mRNA levels compatible with NMD (further restored in presence of CHX) as well as reduced protein levels. The female belonging to the second non-consanguineous family was found to harbor 2 missense variants in trans configuration.

An exocytosis defect was demonstrated in fibroblasts from individuals belonging to both families. Ciliogenesis appeared to be normal, however Arl13b localization/recruitment to the cilia was reduced compared with control cells with the defect rescued upon exogenous expression of wt EXOC2.

Mutations in other genes encoding components of the exocyst complex have been previously reported in individuals with relevant phenotypes (e.g. EXOC8 in a boy with features of Joubert s. or EXOC4 in nephrotic syndrome).

The authors discuss on the essential role of EXOC2 based on model organism studies (e.g. impaired neuronal membrane traffic, failure of neuronal polarization and neuromuscular junction expansion seen in Drosophila Sec5 (EXOC2) null mutants).

Added comment: Pathogenic CEP120 variants have been reported in recessive ciliopathies, namely Short-rib thoracic dysplasia 13 with or without polydactyly (MIM 616300) and Joubert syndrome 31 (MIM 617761).

The former is associated with a severe/lethal outcome (4 unrelated infants described by Shaheen et al 2015 - PMID: 25361962, 2 fetuses reported by Roosing et al 2016 - PMID: 27208211).

Roosing et al however, also provided details on 4 unrelated subjects with Joubert syndrome diagnosis. All presented with a neurologic phenotype of hypotonia, DD, cognitive impairment and exhibited a molar tooth sign.

As a result, this gene can be considered for inclusion in the ID panel with green rating (>3 individuals/variants, consistent ciliopathy phenotype).

Added comment: Biallelic pathogenic ABCA2 variants cause Intellectual developmental disorder with poor growth and with or without seizures or ataxia (MIM 618808).

There are 3 relevant publications (01-07-2020) :
- Maddirevula et al [2019 - PMID: 30237576] described briefly 2 unrelated subjects (16-2987, 16DG0071) both DD and seizures among other manifestations.
- Hu et al [2019 - PMID: 29302074] reported 3 sibs (M8600615 - III:1-3) born to consanguineous parents (M8600615 - III:1-3) with DD/ID (formal confirmation of moderate ID, in those (2) evaluated). One also presented with seizures.
- Aslam and Naz [2019 - PMID: 31047799] provided clinical details on 2 siblings born to consanguineous parents. ID was reported for the older sib but was absent in the younger one. Seizures were not part of the phenotype.

All subjects harbored biallelic pLoF variants.

N.B. : Steinberg et al [2015 - PMID: 25773295], within a cohort of patients with ALS, identified one with biallelic ABCA2 variants. As however Aslam and Naz comment, this person harbored a single pathogenic variant, with a second one rather unlikely to be pathogenic due to high allele frequency.

Overall this gene can be considered for inclusion with green rating in both ID and epilepsy panels (each in >=3 unrelated individuals).

One proband had seizures at 7 months but these were controlled with medication and did not repeat. The other proband at age one had an atypical febrile seizure that was controlled without medication. Functional studies in Drosophila suggest that these variants are mild loss of function mutations but that they can act as dominant negative variants in actin polymerization in bristles.

Added comment: 4 families with 8 affected individuals with brain atrophy, seizures, and developmental delay, and in more severe cases microcephaly and infantile death. Four novel homozygous or comp.heterozygous variants found in EXOC7, which segregated with disease in the families. They showed that EXOC7, a member of the mammalian exocyst complex, is highly expressed in developing human cortex. In addition, a zebrafish model of Exoc7 deficiency recapitulates the human disorder with increased apoptosis and decreased progenitor cells during telencephalon development, suggesting that the brain atrophy in human cases reflects neuronal degeneration.

Added comment: One patient with severe global developmental delay, language impairment and epileptic encephalopathy. Homozygous OTUD7A missense variant (c.697C>T, p.Leu233Phe), predicted to alter an ultraconserved amino acid, lying within the OTU catalytic domain. Its subsequent segregation analysis revealed that the parents, presenting with learning disability, and brother were heterozygous carriers. Biochemical assays demonstrated that proteasome complex formation and function were significantly reduced in patient‐derived fibroblasts and in OTUD7A knockout HAP1 cell line. We provide evidence that biallelic pathogenic OTUD7A variation is linked to early‐onset epileptic encephalopathy and proteasome dysfunction. Gene lies in the chromosome 15q13.3 region. Heterozygous microdeletions of chromosome 15q13.3 show incomplete penetrance and are associated with a highly variable phenotype that may include intellectual disability, epilepsy, facial dysmorphism and digit anomalies.

Added comment: Hu et al (2019 - PMID: 29302074) reported briefly on 3 individuals from 2 consanguineous families (from Turkey and Iran) with biallelic TTC5 variants. Features included DD (3/3), ID (severe in 2/2 with relevant age), microcephaly (3/3), brain abnormalities, etc. A nonsense and a variant affecting splice site were identified by WES/WGS.

---

In a recent report, Rasheed et al (2020 - PMID: 32439809) report on the phenotype of 8 individuals - belonging to 5 consanguineous families - all 8 harboring homozygous TTC5 mutations.

Frequent features included hypotonia (6/8), motor and speech delay, moderate to severe ID (10/10 of relevant age - inclusion of less severely affected subjects was not considered by study design), brain MRI abnormalities (8/8). Other findings included microcephaly in some (6/11), behavioral abnormalities in few (autistic behavior in 2/8, aggression in 2/8), genitourinary anomalies (2/8), seizures (1/11). Facial phenotype incl. thin V-shaped upper lip, low-set ears (in most) and/or additional features.

TTC5 encodes a 440 aa protein, functioning as a scaffold to stabilise p300-JMY interactions. Apart from this role in nucleus, it has functions in the cytoplasm (inhibiting actin nucleataion, autophagosome formation, etc).

The gene has ubiquitous expression, highest in brain.

All variants were identified following WES - as the best candidates - in affected individuals with compatible Sanger studies in all affected family members and carrier parents.

2 missense and 2 nonsense variants were identified with the 2 missense SNVs localizing within TPR domains. qRT-PCR studies for a nonsense variant localizing 19 nt before the last exon, revealed fourfold decreased expression in affected individuals compared to carriers.

Families from Egypt shared a homozygous ~6.3 Mb haplotype block spanning TTC5, suggesting that p.(Arg263Ter) is likely a founder mutation.

The authors underscore some phenotypic (though not facial) similarities with Rubinstein-Taybi syndrome 2 due to EP300 mutations (in line with the role of TTC5).

Biallelic variants in genes encoding other members of the TTC family (containing a TPR motif), e.g. TTC8 or TTC15 cause disorders with neurologic manifestations (and DD/ID).

Nakashima et al (2020 - PMID:32341456) provide clinical details on 3 unrelated individuals with de novo CUL3 variants.

Features included DD, variable degrees of ID (P1: severe, P3: mild, P2: NA although he displayed motor and severe speech and language delay and had severe learning difficulties). Two out of three had intractable seizures (onset 2 - 6 months). One presented with congenital heart defects (ASD, PV stenosis) and another submucosal palatoschisis/bifid uvula. There were no facial dysmorphisms reported.

CUL3 encodes Cullin-3, a core piece of the E3 ubiquitin ligase complex, thus playing a role in the ubiquitin-proteasome system. [ https://ghr.nlm.nih.gov/gene/CUL3 ]. Germline variants in some other Cullin family genes (eg. CUL4B, CUL7) cause disorders with ID as a feature.

The 3 individuals reported by Nakashima had variable previous investigations (karyotype, CMA, metabolic testing) which were non-diagnostic. Singleton or trio exome sequencing identified 2 frameshift and 1 missense variant (NM_003590.4:c.854T>C / p.Val285Ala), further confirmed with Sanger sequencing. De novo occurrence was confirmed by analysis of microsatellite markers in an individual with singleton ES.

While the frameshift variants were presumed to lead to NMD (not studied), studies in HEK293T cells suggested that the Val285Ala reduced binding ability with KEAP1, possibly leading to instability of the Cullin-RING ligase (CRL) complex and impairment of the ubiquitin-proteasome system.

In OMIM, the phenotype associated with heterozygous CUL3 mutations is Pseudohypoaldosteronism type IIE (PHA2E - # 614496). As OMIM and Nakashima et al comment, PHA2E-associated variants are clustered around exon 9, most lead to skipping of exon 9 and produce an in-frame deletion of 57 aa in the cullin homology domain. Few (probably 3) missense variants in exon 9 have also been reported. Individuals with PHA2E do not display DD/ID and conversely individuals with NDD did not display features of PHA2E.

Nakashima et al summarize the phenotypes associated with 12 further de novo CUL3 variants in the literature with most pLOF ones detected in individuals with autism and/or developmental disorders and in few cases with congenital heart disease. Few additional missense variants and a stoploss one have been reported in individuals with NDD and one in SCZ.

Heterozygous Cul3 (/tissue-specific) deletion in mice resulted in autism-like behavior. Cul3 deficient mice also demonstrated NMDAR hypofunction and decreased spine density. [PMIDs cited : 31455858, 31780330]

Overall haploinsufficiency is favored as the underlying mechanism of variants associated with NDD. Nakashima et al comment that the pathogenesis of missense variants remains unknown and/or that a dominant-negative effect on CRL may be possible.

Studies on larger cohorts reporting on individuals with relevant phenotypes due to de novo CUL3 variants (eg. DDD study - PMID: 28135719, Lelieveld et al - PMID: 27479843), are summarized in denovo-db (after filtering for coding variants):

http://denovo-db.gs.washington.edu/denovo-db/QueryVariantServlet?searchBy=Gene&target=cul3

Overall, this gene can be considered for inclusion in the ID (amber/green), epilepsy (amber) and/or ASD panels.

Added comment: Hengel et al (2020 - PMID: 32001716) report on 36 individuals with biallelic UGDH pathogenic variants.

The phenotype corresponded overall to a developmental epileptic encephalopathy with hypotonia, feeding difficulties, severe global DD, moderate or commonly severe ID in all. Hypotonia and motor disorder (incl. spasticity, dystonia, ataxia, chorea, etc) often occurred prior to the onset of seizures. A single individual did not present seizures and 2 sibs had only seizures in the setting of fever.

Affected subjects were tested by exome sequencing and UGDH variants were the only/best candidates for the phenotype following also segregation studies. Many were compound heterozygous or homozygous (~6 families were consanguineous) for missense variants and few were compound heterozygous for missense and pLoF variants. There were no individuals with biallelic pLoF variants identified. Parental/sib studies were all compatible with AR inheritance mode.

UGDH encodes the enzyme UDP-glucose dehydrogenase which converts UDP-glucose to UDP-glucuronate, the latter being a critical component of the glycosaminoglycans, hyaluronan, chondroitin sulfate, and heparan sulfate [OMIM].

Patient fibroblast and biochemical assays suggested a LoF effect of variants leading to impairment of UGDH stability, oligomerization or enzymatic activity (decreased UGDH-catalyzed reduction of NAD+ to NADH / hyaluronic acid production which requires UDP-glucuronate).

Attempts to model the disorder using an already developped zebrafish model (for a hypomorphic LoF allele) were unsuccessful as fish did not exhibit seizures spontaneously or upon induction with PTZ.

Modelling of the disorder in vitro using patient-derived cerebral organoids demonstrated smaller organoids due to reduced number of proliferating neural progenitors.

Added comment: AlMuhaizea et al (2020 - PMID: 32006098) report on the phenotype of 6 individuals (from 5 families) with biallelic YIF1B truncating variants.

Affected subjects presented hypotonia, failure to thrive, microcephaly (5/6), severe global DD and ID (as evident from best motor/language milestones achieved - Table S1) as well as features suggestive of a motor disorder (dystonia/spasticity/dyskinesia). Seizures were reported in 2 unrelated individuals (2/6). MRI abnormalities were observed in some with thin CC being a feature in 3.

Variable initial investigations were performed including SNP CMA, MECP2, microcephaly / neurotransmitter disorders gene panel testing did not reveal P/LP variants.

YIF1B variants were identified in 3 families within ROH. Following exome sequencing, affected individuals were found to be homozygous for truncating variants (4/5 families being consanguineous). The following 3 variants were identified (NM_001039672.2) : c.186dupT or p.Ala64fs / c.360_361insACAT or p.Gly121fs / c.598G>T or p.Glu200*.

YIF1B encodes an intracellular transmembrane protein.

It has been previously demonstrated that - similarly to other proteins of the Yip family being implicated in intracellular traffic between the Golgi - Yif1B is involved in the anterograde traffic pathway. Yif1B KO mice demonstrate a disorganized Golgi architecture in pyramidal hippocampal neurons (Alterio et al 2015 - PMID: 26077767). The rat ortholog interacts with serotonin receptor 1 (5-HT1AR) with colocalization of Yif1BB and 5-HT1AR in intermediate compartment vesicles and involvement of the former in intracellular trafficing/modulation of 5-HT1AR transport to dendrites (PMID cited: 18685031).

Available mRNA and protein expression data (Protein Atlas) suggest that the gene is widely expressed in all tissues incl. neuronal cells. Immunochemistry data from the Human Brain Atlas also suggest that YIF1B is found in vesicles and localized to the Golgi apparatus. Immunohistochemistry in normal human brain tissue (cerebral cortex) demonstrated labeling of neuronal cells (Human Protein Atlas).

Functional/network analysis of genes co-regulated with YIF1B based on available RNAseq data, suggest enrichement in in genes important for nervous system development and function.

Please consider inclusion in other panels that may be relevant (e.g. microcephaly, etc).

Added comment: Chilton et al (2020 - PMID: 32031333) report on 14 individuals with missense and loss-of-function CDC42BPB variants.

Features included hypotonia (8/11), DD (12/13 - the 14th was a fetus), ID (7/13), ASD (8/12), clinical seizures (in 3 - a 4th had abnormal EEG without seizures), behavioral abnormalities. Variable non-specific dysmorphic features were reported in some (sparse hair being the most frequent - 4/8). Additional features were observed in few (=<4) incl. cryptorchidism, ophthalmological issues, constipation, kidney abnormalities, micropenis, etc.

All individuals had non-diagnostic prior genetic testing (incl. CMA, FMR1, MECP2, Angelman/Prader-Willi methylation studies, autism gene panel - suggesting relevance to the current panel) or metabolic testing.

Variants were identified following clinical exome sequencing with Sanger confirmation. Most occurred as de novo events (11/14) while inheritance was not available for few (3/14). Missense variants did not display (particular) clustering.

Almost all variants were absent from gnomAD and were predicted to be deleterious in silico (among others almost all had CADD scores >25).

As the authors comment, CDC42BPB encodes myotonic dystrophy-related Cdc42-binding kinase β (MRCKβ) a serine/threonine protein kinase playing a role in regulation of cytoskeletal reorganization and cell migration in nonmuscle cells (through phosporylation of MLC2).

Previous studies have demonstrated that it is ubiquitously expressed with prenatal brain expression.

The gene appears to be intolerant to pLoF (pLI of 1) as well as to missense variants (Z-score of 3.66).

CDC42BPB is a downstream effector of CDC42. Mutations of the latter cause Takenouchi-Kosaki syndrome with DD/ID and some further overlapping features (with CDC42BPB-associated phenotypes).

Homozygous Cdc42bpb KO in mouse appears to be nonviable (MGI:2136459). Loss of gek in the eyes of Drosophila results in disrupted growth cone targeting to the lamina (gek is the fly CDC42BPB ortholog).

Please consider inclusion with amber / green rating in the ID panel (>=4 relevant individuals / variants) and other panels (e.g. for epilepsy, ASD).

Added comment: Homozygous nonsense variants in CEP55 are associated with a lethal condition characterized by multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly (MARCH syndrome) also known as Meckel-like syndrome. New report of seven living individuals from five families with biallelic CEP55 variants. Four unrelated individuals with microcephaly, speech delays, and bilateral toe syndactyly all had a common CEP55 variant c.70G>A p.(Glu24Lys) in trans with nonsense variants. Three siblings were homozygous for a consensus splice site variant near the end of the gene. These affected girls all had severely delayed development, microcephaly, and varying degrees of lissencephaly/pachygyria. This series suggests that individuals with compound heterozygosity for nonsense and missense variants in CEP55 have a different viable phenotype.

1 family with 2 sibs with GMS and compound heterozygous mutations in the WDR4 gene, segregated with the disorder in the family. Functional studies of the variants and studies of patient cells were not performed.

1 family with 1 child with GMS and compound heterozygous mutations in the WDR4 gene, segregated with the disorder in the family. Functional studies of the variants and studies of patient cells were not performed.

1 family with 4 sibs with GMS and homozygous splice site mutation in the WDR4 gene. Functional studies of the variant and studies of patient cells were not performed.



Microcephaly, growth deficiency, seizures, and brain malformations; OMIM #618346:

2 unrelated patients with intrauterine growth retardation, postnatal growth deficiency with severe microcephaly, and poor or absent psychomotor development. Testing found the same homozygous missense mutation in the WDR4 gene, which segregated with the disorder in both families. Studies of patient cells and modeling of the corresponding mutation in yeast showed that the mutation caused a significant reduction in m(7)G46 methylation of specific tRNAs species, particularly at higher temperatures.

2 unrelated patients with intrauterine growth retardation, postnatal growth deficiency with severe microcephaly, and poor or absent psychomotor development. Testing found the same homozygous missense mutation in the WDR4 gene, which segregated with the disorder in both families. Studies of patient cells and modeling of the corresponding mutation in yeast showed that the mutation caused a significant reduction in m(7)G46 methylation of specific tRNAs species, particularly at higher temperatures. This was associated with a growth defect in yeast, thus offering a potential mechanism for the growth defects observed in patients with the mutation. The findings suggested that abnormal tRNA modification is a major contributor to disease pathogenesis.

Added comment: 3 consanguineous Saudi families with neurodevelopmental disorder with spasticity and poor growth with a homozygous missense mutation in the UFC1 gene. An unrelated Swiss boy with same phenotype found to have a different homozygous mutation in the UFC1 gene. Total 8 patients from 4 families.

The mutations segregated with the disorder in the families. In vitro functional expression studies showed that both mutations caused impaired thioester binding with UFM1 (610553). Patient cells also showed decreased UFC1 intermediate formation with UFM1. The decrease in function was consistent with a hypomorphic allele, and Nahorski et al. (2018) suggested that complete loss of function would be embryonic lethal.

Phenotypes for gene: ZIC1 were set to Structural brain anomalies with impaired intellectual development and craniosynostosis; OMIM #618736 
Review for gene: ZIC1 was set to GREEN
Added comment: 5 families with heterozygous mutations located in the final (third) exon of ZIC1 who have a distinct phenotype in which severe craniosynostosis, specifically involving the coronal sutures, and variable learning disability are the most characteristic features. The location of the nonsense mutations predicts escape of mutant ZIC1 transcripts from nonsense-mediated decay, which was confirmed in a cell line from an affected individual. Both nonsense and missense mutations are associated with altered and/or enhanced expression of a target gene, engrailed-2, in a Xenopus embryo assay. Analysis of mouse embryos revealed a localized domain of Zic1 expression at embryonic days 11.5-12.5 in a region overlapping the supraorbital regulatory center, which patterns the coronal suture.

2 sibs with BAIDCS, Vandervore et al. (2018) identified heterozygosity for a frameshift mutation in the ZIC1 gene. Neither parent had evidence of the mutation by whole-exome sequencing, suggesting that gonadal mosaicism for the mutation was present in one of the parents. Expression of the mutated allele was detected in patient fibroblasts by RT-PCR, evidence that the mutant mRNA did not undergo nonsense-mediated decay and probably generates an abnormal protein.


Also heterozygous deletions of ZIC1 on chromosome 3q25.1 are associated with Dandy-Walker malformation of the cerebellum. Loss of the orthologous Zic1 gene in the mouse causes cerebellar hypoplasia and vertebral defects.

Added comment: 3 unrelated patients with de novo heterozygous missense mutations in GABRA5 gene. In vitro functional expression studies in HEK293 cells showed that the mutant subunit was expressed at the surface and incorporated into the channel, but the mutant channel was 10 times more sensitive to GABA compared to wildtype. This increased sensitization resulted in increased receptor desensitization to GABA, with a reduced maximal GABA-evoked current and impaired capacity to pass GABAergic chloride current.

Added comment: 1 patient with de novo heterozygous missense SNRPE mutation, with non-syndromic primary microcephaly and intellectual disability. SNRPE encodes SmE and they showed that the microcephaly-linked SmE variant is unable to interact with the SMN complex and as a consequence fails to assemble into U snRNPs. This results in widespread mRNA splicing alterations in fibroblast cells derived from this patient. Similar alterations were observed in HEK293 cells upon SmE depletion that could be rescued by the expression of wild type but not mutant SmE. Depletion of SmE in zebrafish causes aberrant mRNA splicing alterations and reduced brain size, reminiscent of the patient microcephaly phenotype.

Added comment: 28 families with spectrum of neurodevelopmental features (including ID, ASD, and ADHD) due to de novo ZNF292 variants (1 family inherited). No functional evidence of specific variants, but ZNF292 is highly expressed in the developing human brain.


14 unrelated patients with neurodevelopmental disorder with dysmorphic facies and distal skeletal anomalies, and de novo heterozygous mutations in the ZMIZ1 gene. Transfection of 3 variants (T300M, c.3112dupA, and K91R) into HEK293T cells resulted in decreased induction of luciferase activity compared to wildtype (although the change for K91R was not statistically significant), suggesting impaired coactivation activity of the mutant proteins. Electroporation of these 3 mutants into progenitor cells in the ventricular zone of embryonic mice cortices resulted in defective neuronal migration to the cortex, as well as morphologic abnormalities of the neurons manifest as rounded cells with aberrantly oriented processes. These findings suggested that the ZMIZ1 mutations disrupted proper neuronal polarization and neuronal migration in the developing cortex. Functional studies of the other variants and additional studies of patient cells were not performed.

In silico sequence analysis demonstrated that the ZNF41 gene was disrupted. Expression studies indicated that ZNF41 transcripts were absent in the patient cell line, suggesting that the mental disorder in this patient resulted from loss of functional ZNF41. Moreover, screening of a panel of patients with MRX led to the identification of 2 other ZNF41 mutations (314995.0001-314995.0002) that were not found in healthy control individuals. Based on their finding of the mutations in ZNF41 identified by Shoichet et al. (2003) in a total of 7 males in the NHLBI Exome Variant Server, and the additional finding of truncating ZNF41 variants in 1 male and 1 female in that database, Piton et al. (2013) classified the involvement of ZNF41 in mental retardation as highly questionable.; to: Shoichet et al.
