Core-binding factor, beta subunit (CBFB) is a gene that encodes a protein that is the beta subunit in a core-binding transcription factor of the PEBP2/CBF family. The protein functions in the regulation of genes that are involved in hematopoiesis. Fusions, missense and nonsense mutations are observed in cancers such as breast cancer and intestinal cancer.

CBFB is altered in 1.18% of all cancers with breast carcinoma, colorectal adenocarcinoma, non-small cell lung carcinoma, ovarian neoplasm, and uterine corpus neoplasm having the greatest prevalence of alterations [3].

CBFB GENIE Cases - Top Diseases

The most common alterations in CBFB are CBFB X55_splice (0.09%), CBFB Loss (0.08%), CBFB Amplification (0.05%), CBFB P70Sfs*13 (0.05%), and CBFB N104S (0.01%) [3].
