The etno-population features of <i>IL-1 β </i>gene polimorfism distribution at <i>Helicobacter pylori</i>-associated gastroduodenal pathology
The aim of this study was to reveal the features of association polymorphisms of interleukin-1 <i>IL-1</i> and the antagonist of receptor for interleukin-1 <i>IL-1Ra</i> gene polymorphism in Mongoloids and Caucasoid from Khakassia with HP-associated gastroduodenal pathology (chronic gastritis and gastric ulcer). It was revealed that among Khakasses the most widespread genotypes among Khakasses are СС <i>IL-1β</i> and R4R4 <i>IL-1Ra</i>. The association of СС +3953 and R2R3 genotypes with GU risk in Caucasoids was found.
