We also found that the rs12979860, rs2227982 and rs36084323 polymorphisms showed no significant associations with susceptibility or spontaneous clearance of HCV in the anti-F antibody subgroup; however, the anti-F antibody positive subgroup might show an increased risk of N-SVR (all P < 0.001).
To investigate the associations of three single nucleotide polymorphisms (SNPs) (rs10204525, rs2227982 and rs36084323) in PD-1 and a previously well-inquired SNP rs12979860 in IL-28B with the outcomes of hepatitis C virus (HCV) infection in Southeast China, a total of 375 healthy controls, 219 spontaneous resolved HCV patients and 600 chronic HCV patients were enrolled in this study.
