Genes affected
HUWE1 (HGNC:30892): (HECT, UBA and WWE domain containing E3 ubiquitin protein ligase 1) This gene encodes a protein containing a C-terminal HECT (E6AP type E3 ubiquitin protein ligase) domain that functions as an E3 ubiquitin ligase. The encoded protein is required for the ubiquitination and subsequent degradation of the anti-apoptotic protein Mcl1 (myeloid cell leukemia sequence 1 (BCL2-related)). This protein also ubiquitinates the p53 tumor suppressor, core histones, and DNA polymerase beta. Mutations in this gene are associated with Turner type X-linked syndromic cognitive disability.

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Nov 22, 2022 | Variant summary: HUWE1 c.329G>A (p.Arg110Gln) results in a conservative amino acid change located in a domain of unknown function DUF908 (IPR010309) in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 183017 control chromosomes (gnomAD). c.329G>A has been reported in the literature as a de novo variant in the heterozygous state in three female individuals affected with intellectual disability and craniosynostosis (e.g. Taylor_2015, Moortgat_2018). In all three cases, these individuals exhibited skewed X-inactivation of the wildtype X chromosome, resulting in preferential expression of the variant allele. These data indicate that the variant is likely associated with disease. Furthermore, a different missense change at the same amino acid, p.Arg110Trp, has been observed in at least one hemizygous male with similar clinical features (e.g. Taylor_2015). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven submitters have provided clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Apr 22, 2024 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 29307790, 25985138, 36939041, 30797980, 32336296, 29180823, 37086723) - |
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 17, 2023 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 110 of the HUWE1 protein (p.Arg110Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with HUWE1-related conditions (PMID: 25985138, 29180823). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 375709). 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. - |
Inborn genetic diseases Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 09, 2020 | The c.329G>A (p.R110Q) alteration is located in exon 6 (coding exon 3) of the HUWE1 gene. This alteration results from a G to A substitution at nucleotide position 329, causing the arginine (R) at amino acid position 110 to be replaced by a glutamine (Q). Based on data from the Genome Aggregation Database (gnomAD), the HUWE1 c.329G>A alteration was not observed, with coverage at this position. This alteration was described as a recurrent de novo alteration in female patients with a neurodevelopmental syndrome that included motor delays, mild intellectual disability, skeletal anomalies, craniosynostosis, and facial dysmorphic features. All females showed skewed inactivation of the X chromosome favoring the affected allele (Taylor, 2015; Moortgat, 2018). The p.R110 amino acid is conserved in available vertebrate species. The p.R110Q alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic. - |
