Genes affected

BNIP3L (HGNC:1085): (BCL2 interacting protein 3 like) This gene encodes a protein that belongs to the pro-apoptotic subfamily within the Bcl-2 family of proteins. The encoded protein binds to Bcl-2 and possesses the BH3 domain. The protein directly targets mitochondria and causes apoptotic changes, including loss of membrane potential and the release of cytochrome c. [provided by RefSeq, Feb 2015]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.17926532).

The c.83C>T (p.P28L) alteration is located in exon 1 (coding exon 1) of the BNIP3L gene. This alteration results from a C to T substitution at nucleotide position 83, causing the proline (P) at amino acid position 28 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
