KRAS and familial pancreatic carcinoma: Figures 7C,D showed the frequencies of genetic mutations in two groups. Both in high and low m6A score groups, FRG1B, KRAS, TP53, TCF20, MED12L, PRG4, OTUD4, and MYH9 were the eight most frequently mutated genes. Missense mutation was the main mutation type in pancreatic cancer. Figures 7E,F showed the distributions of CNV regions in two groups.
