Genes affected

BNIP1 (HGNC:1082): (BCL2 interacting protein 1) 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. In addition, this protein is involved in vesicle transport into the endoplasmic reticulum. Alternative splicing of this gene results in four protein products with identical N- and C-termini.

The c.400A>C (p.N134H) alteration is located in exon 5 (coding exon 5) of the BNIP1 gene. This alteration results from a A to C substitution at nucleotide position 400, causing the asparagine (N) at amino acid position 134 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
