Genes affected

HERC4 (HGNC:24521): (HECT and RLD domain containing E3 ubiquitin protein ligase 4) HERC4 belongs to the HERC family of ubiquitin ligases, all of which contain a HECT domain and at least 1 RCC1 (MIM 179710)-like domain (RLD). The 350-amino acid HECT domain is predicted to catalyze the formation of a thioester with ubiquitin before transferring it to a substrate, and the RLD is predicted to act as a guanine nucleotide exchange factor for small G proteins (Hochrainer et al., 2005 [PubMed 15676274]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.849

The c.3029A>G (p.Q1010R) alteration is located in exon 26 (coding exon 24) of the HERC4 gene. This alteration results from a A to G substitution at nucleotide position 3029, causing the glutamine (Q) at amino acid position 1010 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
