Variant summary
Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PM2PM5PP3_ModeratePP5_Very_Strong
The NM_031407.7(HUWE1):c.9208C>T(p.Arg3070Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R3070H) has been classified as Pathogenic.

The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.87; 3Cnet: 0.94). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000280723). A different missense change at the same codon (p.Arg3070His) has been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000841299). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 3070 of the HUWE1 protein (p.Arg3070Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with HUWE1-related disease (PMID: 29180823). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 280723). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HUWE1 protein function. For these reasons, this variant has been classified as Pathogenic. -
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 29180823, 32336296, 31130284, 33710394, 33504798) -

Inborn genetic diseases Pathogenic:1
The c.9208C>T (p.R3070C) alteration is located in exon 65 (coding exon 62) of the HUWE1 gene. This alteration results from a C to T substitution at nucleotide position 9208, causing the arginine (R) at amino acid position 3070 to be replaced by a cysteine (C). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This variant has been reported in both heterozygous female and hemizygous male individual(s) with features consistent with HUWE1-related neurodevelopmental disorder; in at least one individual, it was determined to be a de novo variant (Moortgat, 2018; Monies, 2019; Järvelä, 2021; Zhou, 2022; Schmidt, 2024). This amino acid position is well conserved in available vertebrate species. This missense alteration is located in a region that has a low rate of benign missense variation (Lek, 2016; Firth, 2009). This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic. -
