Genes affected

SIAH2 (HGNC:10858): (siah E3 ubiquitin protein ligase 2) This gene encodes a protein that is a member of the seven in absentia homolog (SIAH) family. The protein is an E3 ligase and is involved in ubiquitination and proteasome-mediated degradation of specific proteins. The activity of this ubiquitin ligase has been implicated in regulating cellular response to hypoxia. [provided by RefSeq, Jul 2008]

The c.968G>A (p.C323Y) alteration is located in exon 2 (coding exon 2) of the SIAH2 gene. This alteration results from a G to A substitution at nucleotide position 968, causing the cysteine (C) at amino acid position 323 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
