ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between the SNP rs10774671 on OAS-1 gene and spontaneous HBeAg seroconversion in chronic HBV infection.</p><p><b>METHODS</b>Blood samples were collected from 58 HBeAg positive, 68 anti-HBe positive patients with chronic HBV infection, and 72 normal control cases without HBV infection. Chromosomal DNA was extracted and OAS-1 gene was amplified. SNP genotyping was performed with the competitively differentiated polymerase chain reaction and enzyme immunoassay.</p><p><b>RESULTS</b>In HBeAg positive group, frequencies of genotype GG plus GA and allele G were 31.0% and 16.4%. They were 48.5% and 29.4% in anti-HBe positive group, and 50.0% and 28.4% in normal control group respectively. Differences between HBeAg positive group and anti-HBe positive group or normal control group were statistically significant. But they weren't between anti-HBe positive group and normal control group.</p><p><b>CONCLUSION</b>Allele G on SNP rs10774671 of OAS-1 gene maybe benefits patients with chronic HBV infection to achieve spontaneous HBeAg seroconversion. Genotyping on this SNP may be predicting valuable for interferon therapy for chronic HBV infection.</p>
