Genes affected
HERC5 (HGNC:24368): (HECT and RLD domain containing E3 ubiquitin protein ligase 5) This gene is a member of the HERC family of ubiquitin ligases and encodes a protein with a HECT domain and five RCC1 repeats. Pro-inflammatory cytokines upregulate expression of this gene in endothelial cells. The protein localizes to the cytoplasm and perinuclear region and functions as an interferon-induced E3 protein ligase that mediates ISGylation of protein targets. The protein also acts as a modulator of the antiviral immune response. The gene lies in a cluster of HERC family genes on chromosome 4. [provided by RefSeq, Aug 2021]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 08, 2024The c.809G>C (p.G270A) alteration is located in exon 6 (coding exon 6) of the HERC5 gene. This alteration results from a G to C substitution at nucleotide position 809, causing the glycine (G) at amino acid position 270 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
