Genes affected

BIRC3 (HGNC:591): (baculoviral IAP repeat containing 3) This gene encodes a member of the IAP family of proteins that inhibit apoptosis by binding to tumor necrosis factor receptor-associated factors TRAF1 and TRAF2, probably by interfering with activation of ICE-like proteases. The encoded protein inhibits apoptosis induced by serum deprivation but does not affect apoptosis resulting from exposure to menadione, a potent inducer of free radicals. It contains 3 baculovirus IAP repeats and a ring finger domain. Transcript variants encoding the same isoform have been identified. [provided by RefSeq, Aug 2011]

The c.719A>G (p.Q240R) alteration is located in exon 1 (coding exon 1) of the BIRC3 gene. This alteration results from a A to G substitution at nucleotide position 719, causing the glutamine (Q) at amino acid position 240 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
