A best MDR model composed of PD1 rs2227982, rs41386349, and rs7421861, and TIM3 rs11134551, rs11742259, rs246871, rs25855, and rs31223 was observed between patients with chronic HBV infection and HBV infection resolvers (maximum testing balance accuracy, 0.5803; maximum cross-validation consistency, 9/10; P = 0.0010).
Our study found that rs31223 and rs246871 were associated with disease progression of HBV infection, while none of the three SNPs was relevant to HBV susceptibility.
