We ascertained the role of the immune response of FANCD2 in HCC with PD-1, PD-L1, or CTLA-4 using TIMER data and found that FANCD2 expression was strongly statistically associated with PD-1, PD-L1, and CTLA-4 in HCC (Figures 9B–D), demonstrating that FANCD2 might mediate HCC carcinogenesis of immune escape. The gene discussed is CD274; the disease is hepatocellular carcinoma.
