Baculovial IAP repeat containing 3 (BIRC3) is a gene that encodes encodes the protein cellular inhibitor of apoptosis protein 2 (cIAP2), which inhibits apoptosis. BIRC3 is localized to chromosome 11q22, whose deletion is associated with high risk disease in patients with chronic lymphocytic leukemia. BIRC3 mutations are observed in <5% of patients with CLL (PMID: 24943832; PMID: 24597984; PMID: 24217197; PMID: 22308293; PMID: 25605254), ~11% of patients with Splenic marginal zone lymphoma (PMID: 21881048) and 6-10% of mantle cell lymphoma cases (PMID: 24362935).

BIRC3 is altered in 0.82% of all cancers with breast invasive ductal carcinoma, cutaneous melanoma, lung adenocarcinoma, colon adenocarcinoma, and head and neck squamous cell carcinoma having the greatest prevalence of alterations [3].
