Genes affected

BNIP2 (HGNC:1083): (BCL2 interacting protein 2) This gene is a member of the BCL2/adenovirus E1B 19 kd-interacting protein (BNIP) family. It interacts with the E1B 19 kDa protein, which protects cells from virally-induced cell death. The encoded protein also interacts with E1B 19 kDa-like sequences of BCL2, another apoptotic protector. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

Collection Method: clinical testing

The c.755G>A (p.R252H) alteration is located in exon 5 (coding exon 5) of the BNIP2 gene. This alteration results from a G to A substitution at nucleotide position 755, causing the arginine (R) at amino acid position 252 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
