However, among those who carried the CG/GG genotypes of miR-199a rs74723057, those who carried the GG genotype of MET rs1621 had a decreased risk of HCC (OR = 0.15, 95% CI = 0.03~0.73, P for interaction = 0.018), when compared with those who carried the wild-type AG/AA genotypes of MET rs1621. The gene discussed is MET; the disease is hepatocellular carcinoma.
