Important immune checkpoint genes responsible for tumor immune escape include CD274, CTLA4, HAVCR2, LAG3, PDCD1, PDCD1LG2, SIGLEC15, and TIGIT. Considering the possible tumorigenic role of CAMSAP1 in LIHC, we evaluated the correlation between CAMSAP1 expression and these genes. The gene discussed is PDCD1LG2; the disease is neoplasm.
