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.

The c.3520C>G (p.L1174V) alteration is located in exon 32 (coding exon 29) of the HUWE1 gene. This alteration results from a C to G substitution at nucleotide position 3520, causing the leucine (L) at amino acid position 1174 to be replaced by a valine (V). Based on data from the Genome Aggregation Database (gnomAD) database, the HUWE1 c.3520C>G alteration was observed in 0.003% (5/182,105) of total alleles studied, with a frequency of 0.007% (2/27,384) in the Latino subpopulation. This amino acid position is highly conserved in available vertebrate species. The p.L1174V alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
