Programmed cell death 1 ligand 2 (PDCD1LG2; also known as PDL2) is a gene that encodes a protein that functions in the costimulatory signal that is required for T-cell proliferation and IFNG production. The interaction of the protein with PDCD1 blocks T-cell proliferation. Fusions, missense mutations, silent mutations, and frameshift deletions are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.

PDCD1LG2 is altered in 0.83% of all cancers with lung adenocarcinoma, breast invasive ductal carcinoma, colon adenocarcinoma, bladder urothelial carcinoma, and high grade ovarian serous adenocarcinoma having the greatest prevalence of alterations [3].
