Programmed cell death 1 (PDCD1) is a gene that encodes a cell surface membrane protein that belongs to the immunoglobulin superfamily. The protein functions in the differentiation of pro-B-cells. The protein may also be important for T-cell functioning and the prevention of autoimmune diseases. Missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame insertions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

PDCD1 is altered in 0.29% of all cancers with uterine corpus leiomyosarcoma, prostate adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

The most common alterations in PDCD1 are PDCD1 Loss (0.18%) and PDCD1 Amplification (0.00%) [3].
