In conclusion, we have identified two potentially functional SNPs (METTL3 rs1263790 A > G and ADARB1 rs57884102 C > T) in m6A modification genes significantly associated with the survival of HBV‐HCC and may be potential prognostic markers for HBV‐HCC. The gene discussed is ADARB1; the disease is hepatocellular carcinoma.
