Genes affected

BAG5 (HGNC:941): (BAG cochaperone 5) The protein encoded by this gene is a member of the BAG1-related protein family. BAG1 is an anti-apoptotic protein that functions through interactions with a variety of cell apoptosis and growth related proteins including BCL-2, Raf-protein kinase, steroid hormone receptors, growth factor receptors and members of the heat shock protein 70 kDa family. This protein contains a BAG domain near the C-terminus, which could bind and inhibit the chaperone activity of Hsc70/Hsp70. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.740G>C (p.G247A) alteration is located in exon 2 (coding exon 2) of the BAG5 gene. This alteration results from a G to C substitution at nucleotide position 740, causing the glycine (G) at amino acid position 247 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
