Folliculin (FLCN) is a gene that encodes a protein that functions in the pathogenesis of a rare form of kidney cancer. The protein may also have roles in tumor suppression, colorectal tumorigenesis, and energy/nutrient sensing in certain signaling pathways. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions and insertions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

FLCN is altered in 1.45% of all cancers with colorectal adenocarcinoma, breast carcinoma, sarcoma, non-small cell lung carcinoma, and uterine corpus neoplasm having the greatest prevalence of alterations [3].

The most common alterations in FLCN are FLCN Mutation (1.05%), FLCN Mutation (germline) (1.05%), FLCN Amplification (0.24%), FLCN Loss (0.13%), and FLCN H429Tfs*39 (0.11%) [3].
