The somatic mutation of eight risk PRGs (CASP4, GPX4, GSDMC, TLR3, NLRP1, PLCG1, IL18, and IRF1) hardly occurred in PAAD samples but were commonly observed in colon adenocarcinoma (COAD) and stomach adenocarcinoma (STAD) ones (Figure 6a). The gene discussed is PLCG1; the disease is colon adenocarcinoma.
