ASSOCIATIONS OF INTERFERON GENE POLYMORPHISMS OAS-1, OAS-3, PKR WITH CHRONIC VIRAL HEPATITIS C

Abstract

Abstract. Present work is devoted to analyzing possible associations of single-nucleotide gene polymorphisms (SNPs) with liver pathology in patients with chronic hepatitis C. SNP genotypes and allele frequencies were identified for some genes of interferon system, i.e., oligoadenilatsynthetase-1 (-1A/G), oligoadenilatsynthetase-3 (+1314C/T), and protein kinase R (+244A/G), using DNA samples from healthy donors and patients with chronic hepatitis C representing population of Tomsk and Tomsk Region. An association has been shown between SNPs of oligoadenilatsynthetase-1 and protein kinase R genes, and clinical activity of inflammatory process in the liver, as well as an impact of certain SNPs of protein kinase R and oligoadenilatsynthetase-3 genes upon fibrogenesis.
