Data obtained suggest that the OAS2 rs1293762 and CD209 rs2287886 SNPs are associated with predisposition to chronic hepatitis C in Russian population.
Polymorphisms in the OAS1 (rs1131454 and rs10774671), OAS3 (rs2285932 and rs2072136) and OAS2 (rs15895 and rs1732778) genes were studied using PCR followed by restriction fragment length polymorphism methods in 109 patients hospitalized for dengue (DEN) and 105 healthy controls (HCs) who have no documented evidence of symptomatic dengue.
In EV71-infected patients, the CA genotype distribution (P=0.007), A allele frequency (OR 1.32,95% CI 1.0-1.7, P=0.034) and CA+AA carriage frequency (P=0.003) of OAS2 rs739901 5'-flanking were obviously elevated as compared with controls, but there were no statistically significant differences between mild cases and encephalitis cases.
