Polymorphism of 2′-5′-oligoadenylate synthetase (OAS) genes, associated with predisposition to severe forms of tick-borne encephalitis, in human populations of North Eurasia
2′-5′-oligoadenylate synthetases are a family of interferon-induced enzymes playing an important role in antiviral defense in mammals. In the human genome, three genes encoding functional synthetases (OAS1, OAS2 and OAS3) form a cluster. Previously, we found that particular genotypes and/or alleles...

2′-5′-oligoadenylate synthetases are a family of interferon-induced enzymes playing an important role in antiviral defense in mammals. In the human genome, three genes encoding functional synthetases (OAS1, OAS2 and OAS3) form a cluster. Previously, we found that particular genotypes and/or alleles of five single nucleotide polymorphisms (SNPs) of OAS2 and OAS3 are associated with predisposition to severe forms of tick-borne encephalitis (TBE) in Russians. In the current study, we investigated the distribution of three of the above SNPs, OAS3 rs2285932 (C/T, Ile438Ile), OAS3 rs2072136 (G/A, Ser567Ser), and OAS2 rs15895 (G/A, Trp720Ter relative to p71 isoform), in seven populations of North Eurasia: Caucasians (Russians, Germans from Altai region), Central Asian Mongoloids (Altaians, Khakass, Tuvinians, and Shorians), and Arctic Mongoloids (Chukchi).
