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.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The HUWE1 c.12860C>T (p.Ser4287Phe) variant, to our knowledge, has not been reported in the medical literature but has been reported in the ClinVar database as a germline variant of uncertain significance by two submitters. This variant is absent from the general population (gnomAD v.2.1.1), but is observed on 1/10,563 alleles in the ESP 6500, indicating it is not a common variant. Computational predictors are uncertain as to the impact of this variant on HUWE1 function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -
