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.

HUWE1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.68).
• BP6: Variant X-53592404-C-T is Benign according to our data. Variant chrX-53592404-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 211165.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1, Benign=2}.
• BP7: Synonymous conserved (PhyloP=-0.508 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00117 (130/111290) while in subpopulation AFR AF= 0.00402 (123/30607). AF 95% confidence interval is 0.00344. There are 0 homozygotes in gnomad4. There are 25 alleles in male gnomad4 subpopulation. Median coverage is 22. This position pass quality control queck.
• BS2: High Hemizygotes in GnomAd4 at 25 XL gene

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
