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.477A>T (p.R159S) alteration is located in exon 1 (coding exon 1) of the BIRC3 gene. This alteration results from a A to T substitution at nucleotide position 477, causing the arginine (R) at amino acid position 159 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
