ABSTRACT
<p><b>OBJECTIVE</b>To explore whether the TNFA promoter single nucleotide polymorphisms (SNPs) are associated with the outcomes of hepatitis B virus(HBV) infection in Chinese Han population.</p><p><b>METHODS</b>One hundred and forty-eight self-limited HBV infection subjects and 207 chronic hepatitis B patients were recruited. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequence specific primer-PCR(PCR-SSP) were used to detect the SNPs of five sites in TNFA promoter (-238G/A, -308G/A, -857C/T, -863C/A, -1031T/C). The frequency distributions of genotypes and haplotypes in different groups were analyzed by EPI and EH programs.</p><p><b>RESULTS</b>The frequencies of -238GG genotype in chronic hepatitis B patients were significantly higher than that in self-limited infection subjects (P=0.02). The frequencies of -857TT genotype in chronic hepatitis B patients were clearly lower than that in self-limited infection subjects (P=0.02). Haplotypic frequencies of GGCCT (-238/-308/-857/-863/-1031) in chronic hepatitis B patients was significantly lower than that in self-limited infection subjects (P=0.03), and the frequencies of haplotype GGCAT or GGTAT in chronic hepatitis B patients were clearly higher than those in self-limited infection subjects (P=0.0001; P=0.004).</p><p><b>CONCLUSION</b>TNFA promoter polymorphisms are important host genetic factors affecting the outcomes of HBV infection.</p>
