Notably, CD274/PD-L1, PDCD1LG2/PD-L2, PDCD1/PD1, cytotoxic T lymphocyte-associated antigen 4 (CTLA4), T cell membrane protein 3 (TIM3; also known as HAVCR2), and lymphocyte activation gene 3 (LAG3) were correlated to FAM72A across different cancers. This evidence concerns the gene HAVCR2 and cancer.
