Genes affected

BCL2 (HGNC:990): (BCL2 apoptosis regulator) This gene encodes an integral outer mitochondrial membrane protein that blocks the apoptotic death of some cells such as lymphocytes. Constitutive expression of BCL2, such as in the case of translocation of BCL2 to Ig heavy chain locus, is thought to be the cause of follicular lymphoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

BCL2 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.293 is higher than 0.05.
