These findings suggest that PD1 rs41386349 and rs6710479 and TIM3 rs246871 and interactions between PD1 and TIM3 polymorphisms may affect the susceptibility of chronic HBV infection and PD1 rs2227982, rs6710479, and rs7421861 may implicate in hepatocarcinogenesis.
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.

The minor allele "C" of rs31223 was found to be associated with an increased probability of HBsAg seroclearance (P = 0.033) and genotype "CC" of rs246871 to be associated with an increased probability of HBV-associated HCC (P = 0.007).
