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.

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, HUWE1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.797
• PP5: Variant X-53591082-G-A is Pathogenic according to our data. Variant chrX-53591082-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 216942.Status of the report is criteria_provided_single_submitter, 1 stars.
