| Mendeliome v1.3104 | SLC38A6 |
Bryony Thompson gene: SLC38A6 was added gene: SLC38A6 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: SLC38A6 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: SLC38A6 were set to 40931016 Phenotypes for gene: SLC38A6 were set to essential tremor MONDO:0003233 Review for gene: SLC38A6 was set to AMBER Added comment: The study identified SLC38A6 variants in 71 unrelated Chinese ET families (≈9.2% of families) and 47 unrelated sporadic cases, with 15 distinct protein‑altering variants. However, many of the 15 variants are >2% in the East Asian population, which is inconsistent with the incidence of essential tremor in the population (~1%). The study does not contain any statistical enrichment analyses or case-control analyses. It also reports incomplete segregation and non-segregation of variants (called a phenocopy by the authors). A null mouse model (Slc38a6-/-) displays tremor and delineated cerebellar cellular abnormalities. In vitro assessment of 3 of the most common missense variants (p.Y108F [gnomAD total 0.0002; East Asian 0.006, p.M281T [gnomAD total 0.0015; East Asian 0.0227] and p.G318S [gnomAD total 0.0021; East Asian 0.0278]) significantly impaired L-arginine (L-Arg) uptake in HeLa cells. Given the prevalence of the reported variants in the East Asian population, the genetic evidence for this gene-disease association is limited. Sources: Literature |

Zornitza Stark gene: ZNF319 was added gene: ZNF319 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: ZNF319 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: ZNF319 were set to 40820230 Phenotypes for gene: ZNF319 were set to Leukodystrophy, MONDO:0019046, ZNF319-related Review for gene: ZNF319 was set to RED Added comment: Single individual with homozygous missense variant reported, p.Phe267Ser. 18-year-old male presenting with spasticity, ataxia, cognitive decline, and white matter abnormalities on MRI. Molecular dynamics simulations revealed that F267 is a stabilizing residue within a β-strand of the zinc finger domain, forming π-stacking and hydrophobic interactions that are lost upon substitution with serine, leading to structural instability, increased flexibility, and protein unfolding. Despite normal transcript and protein expression, ZNF319-F267S mislocalized to the cytoplasm due to disruption of its bipartite nuclear localization signal (NLS), resulting in impaired interaction with importin α1 (KPNA1). Functional analysis confirmed that the variant disrupts nuclear transport and prevents transcriptional activation of genes involved in myelination. Protein interaction network and gene ontology analysis highlighted ZNF319's role in transcriptional regulation and its localization in the CHOP-C/EBP transcriptional complex. Expression profiling demonstrated ZNF319 enrichment in oligodendrocytes and white matter regions, correlating with the observed leukoencephalopathy. Sources: Literature |

| Mendeliome v1.3022 | KRT32 |
Bryony Thompson gene: KRT32 was added gene: KRT32 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: KRT32 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: KRT32 were set to 40814173; 39048559 Phenotypes for gene: KRT32 were set to loose anagen syndrome MONDO:0010908; Pityriasis rubra pilaris MONDO:0100017 Review for gene: KRT32 was set to GREEN Added comment: Sufficient evidence for Pityriasis rubra pilaris association, but limited for association with loose anagen syndrome. PMID: 39048559 - Significant enrichment of KRT32 variants (p=3.06e-4) in 58 PRP cases vs 364 healthy controls (4 variants - individual 1: c.344G>A (p.Arg115Gln - 10 hets gnomAD v4.1), individual 2: c.477_478del (p.Thr160fs), individual 3: c.607C>T (p.Arg203Cys - 71 hets gnomAD v4.1), and individual 4: c.685T>C (p.Cys229Arg - 18 hets gnomAD v4.1). Validation cohort of 44 PRP cases vs 436 healthy controls identified an additional 2 variants (individual 5: c.907G>A (p.Glu303Lys - 3 hets gnomAD v4.1), individual 6: c.937A>G (p.Ile313Val - 30 hets gnomAD v4.1). A combined analysis of the KRT32 gene in both the discovery and validation cohorts revealed a significant p value of 1.73 e-6. The KRT32 expression patterns (location of protein expression) were altered in PRP cases with the KRT32 variants. In vitro analysis demonstrated that the 6 variants (all located in the IF rod domain) exhibited varying degrees of attenuation in inhibiting the NF-κB signaling pathway. A Krt32 knockout mouse model recapitulates the human PRP-like phenotype. PMID: 40814173 - a single family with loose anagen hair syndrome co-segregating (c.296C>T; p.Thr99Ile) in a large family; however, the AF in the European population is 0.3% in gnomAD v4.1 (6 homozygotes), which is higher than expected for a dominant condition. In vitro functional assay showing the variant alters interaction with KRT82, however, only WT & the variant were assessed (no positive control). Sources: Literature |

| Mendeliome v1.2977 | CSMD2 |
Krithika Murali changed review comment from: PMID: 40632521 Li et al 2025 (Epilepsia) reported 6 unrelated individuals of Han Chinese descent with biallelic CSMD2 missense variants (NM_052896) and focal epilepsy. 5 individuals were compound heterozygous and one was homozygous. These individuals were ascertained through trio WES analysis of 420 unrelated individuals with focal epilepsy enrolled in the China Epilepsy Gene 1.0 project. Phenotypic features - age of onset 1.5-10 years old - complex partial seizures (4), secondary GTCS (2) - Normal MRI-B (3), focal cortical dysplasia (1) - mild ID (1). The variants were noted to be rare in EXAC-East Asian cohort, most located in CUB/Sushi domains. The gene has some evidence of missense and LoF constraint in gnomAD v4. There was also enrichment of biallelic CSMD2 variants in affected individuals versus a control cohort of unaffected parents (5/420 compound hets affected individuals, 3/1942 compound hets in unaffected parents). Previous mouse Csmd2 knockdown models demonstrated reduction in dendritic spine density and complexity. LoF is the postulated disease mechanism. Closely related gene paralog CSMD1 has a definitive association with autosomal recessive complex neurodevelopmental disorder with a more severe phenotype. Different expression profiles during developmental stages between CSMD1 and CSMD2 postulated for the comparatively milder phenotype associated with the latter. CSMD2 has 71 exons and 3631 amino acids. The true prevalence of biallelic missense variants in healthy individuals across diverse ancestries has not been ascertained. Review of the missense variants in this study highlighted issues in a number of them including poor-moderate conservation, conflicting or benign in silicos including REVEL, non-coding in an alternative transcript, Case 4 p.Val1547Ile homozygote – this variant has been noted in an East Asian male homozygote aged between 45-50 in gnomAD v4. In addition, no information about unaffected siblings and segregation testing has been provided.

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.

Zornitza Stark changed review comment from: Variants in AGTR2 have been reported in individuals presenting various neurodevelopmental phenotypes, including intellectual disability, autistic features, epileptic seizures, speech delay, restlessness, and hyperactivity, as early as 2002. Per criteria outlined by the ClinGen Lumping and Splitting Working Group, we found no difference in molecular mechanism, inheritance pattern, or phenotypic variability. Therefore, for the purposes of this curation, all of these features have been lumped into one disease entity, X-linked complex neurodevelopmental disorder. Although eight unique variants, including missense and truncating, have been reported in affected humans, the majority (six) have been ruled out from disease-causality based on high frequency in control populations (Piton et al., PMID 23871722), occurrence in unaffected males (Erdmann et al., PMID 14722754), non-segregation within a family (Bienvenu et al., PMID 12746399), and lack of enrichment in patients in a case-control study (Huang et al., PMID 16283672). Given that the two remaining variants are missense with no supporting functional evidence, and AGTR2 was the only gene sequenced in each case, the ClinGen Intellectual Disability and Autism Working Group recommended awarding 0 points for these variants.

Additionally, experimental evidence showed that AVPR1A is possibly involved in social behaviors, including affiliation and attachment (PMID: 24924430). However, these association studies were underpowered—sequencing more individuals may have identified variants of functional significance. In two studies, transmission disequilibrium between AVPR1A microsatellites and autism were found but most were not statistically significant (PMID: 12082568, 16520824). In another study, investigators screened AVPR1A exons in 125 independent autistic probands (PMID: 15098001). However, the study did not demonstrate a disease-causing variant in the coding sequence, and the authors noted that differences in AVPR1A at the amino-acid level are unlikely to confer genetic vulnerability to autism. Experimental evidence is available, but, in the absence of human genetic evidence, such data were not utilized in the scoring. In summary, there is no valid genetic evidence to support an association between AVPR1A and autism spectrum disorder. Sources: Expert list |

Both had retinal detachment and interstitial parenchymal pulmonary changes on chest X-rays, but only one child had additional significant features such as cataract, posterior encephalocele, severe DD/ID with ASD, and epilepsy. WES revealed a heterozygous PAK2 variant (c.1303 G>A, p.Glu435Lys) in both individuals that apparently occurred de novo indicating parental germ-line mosaicism; however, mosaicism could not be detected by deep sequencing of blood parental DNA. Functional studies showed that the variant, located in the kinase domain, results in a partial loss of the kinase activity. Sources: Literature |

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.

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].

| Mendeliome v0.3732 | FAM50A |
Zornitza Stark gene: FAM50A was added gene: FAM50A was added to Mendeliome. Sources: Literature Mode of inheritance for gene: FAM50A was set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) Publications for gene: FAM50A were set to 32703943 Phenotypes for gene: FAM50A were set to Mental retardation syndrome, X-linked, Armfield type (MIM #300261) Review for gene: FAM50A was set to GREEN 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.). Sources: Literature |

| Mendeliome v0.3643 | NARS |
Zornitza Stark gene: NARS was added gene: NARS was added to Mendeliome. Sources: Literature Mode of inheritance for gene: NARS was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal Publications for gene: NARS were set to 32738225 Phenotypes for gene: NARS were set to Abnormal muscle tone; Microcephaly; Global developmental delay; Intellectual disability; Seizures; Ataxia; Abnormality of the face; Demyelinating peripheral neuropathy Review for gene: NARS was set to GREEN Added comment: [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 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). Sources: Literature |
