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]

The c.2728G>A (p.A910T) alteration is located in exon 24 (coding exon 22) of the HERC4 gene. This alteration results from a G to A substitution at nucleotide position 2728, causing the alanine (A) at amino acid position 910 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
