Genes affected
BAG1 (HGNC:937): (BAG cochaperone 1) The oncogene BCL2 is a membrane protein that blocks a step in a pathway leading to apoptosis or programmed cell death. The protein encoded by this gene binds to BCL2 and is referred to as BCL2-associated athanogene. It enhances the anti-apoptotic effects of BCL2 and represents a link between growth factor receptors and anti-apoptotic mechanisms. Multiple protein isoforms are encoded by this mRNA through the use of a non-AUG (CUG) initiation codon, and three alternative downstream AUG initiation codons. A related pseudogene has been defined on chromosome X. [provided by RefSeq, Feb 2010]

The c.899A>G (p.N300S) alteration is located in exon 6 (coding exon 6) of the BAG1 gene. This alteration results from a A to G substitution at nucleotide position 899, causing the asparagine (N) at amino acid position 300 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
