B-cell CLL/lymphoma 2 (BCL2) is a gene that encodes a protein that functions as an integral outer mitochondrial membrane protein. The protein inhibits the apoptotic death of cell such as lymphocytes. Fusions, missense mutations, silent mutations, frameshift deletions, and in-frame deletions are observed in cancers such as bone cancer, hematopoietic and lymphoid cancer, and stomach cancer.

BCL2 is altered in 0.97% of all cancers with follicular lymphoma, diffuse large B-cell lymphoma, not otherwise specified, colon adenocarcinoma, lung adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

BCL2 GENIE Cases - Top Diseases

The most common alterations in BCL2 are BCL2 Mutation (0.57%), BCL2 Loss (0.26%), BCL2 Amplification (0.13%), BCL2 Fusion (0.11%), and BCL2-IGH Fusion (0.23%) [3].
