Genetic variations of SOCS1 are associated with chronic hepatitis B virus infection.
Suppressor of cytokine signaling (SOCS)-1 is involved in viral infection through regulation of both innate and adaptive immunity. The SOCS1 gene polymorphisms may affect the outcome of viral infection. The relationship between SOCS1 polymorphisms and hepatitis B virus (HBV) infection has not yet been explored. This study genotyped SOCS1 rs243327 and rs33932899 polymorphisms in 477 patients with chronic HBV infection, 93 HBV infection resolvers and 215 healthy controls. In statistical analysis, p-values less than 0.05 in multiple comparisons were corrected by Bonferroni method and presented as pc. The results showed that the allele T-containing genotypes (CT+TT) of rs243327 were higher in HBV patients than resolvers and lower in resolvers than healthy controls although the difference was not significant. The allele T of rs243327 was significantly lower in resolvers than controls (p = 0.033). The genotype GC and allele C of rs33932899 were significantly less frequent in HBV patients than controls (pc < 0.001 and p < 0.001, respectively). The haplotype T/G of rs243327/rs33932899 was significantly more frequent in HBV patients than resolvers (pc < 0.001) or controls (pc = 0.009). These data indicate that SOCS1 polymorphisms might affect the susceptibility and outcome of HBV infection.
