Checkpoint kinase 2 (CHEK2) is a gene that encodes a protein that functions as a regulator of the cell cycle as well as a tumor suppressor. The protein is activated in the presence of DNA damage in order to prevent entry into mitosis. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions and insertions are observed in cancers such as cancers of the central nervous system, endometrial cancer, and intestinal cancer.

CHEK2 is altered in 1.60% of all cancers with non-small cell lung carcinoma, breast carcinoma, colorectal adenocarcinoma, uterine corpus neoplasm, and bladder carcinoma having the greatest prevalence of alterations [3].

CHEK2 GENIE Cases - Top Diseases

The most common alterations in CHEK2 are CHEK2 Mutation (1.40%), CHEK2 Mutation (germline) (1.40%), CHEK2 Amplification (0.10%), CHEK2 Frameshift (0.10%), and CHEK2 Frameshift (germline) (0.10%) [3].
