[Association of cytokine gene polymorphisms in peptic ulcer development in the Bashkortostan Republic].

Peptic ulcer disease (PUD) is a chronic disease based on recurrent gastric or duodenal ulcers. Association analysis of common polymorphisms of the cytokines genes IL1B (rs1143634), IL1RN (rs71941886), IL8 (rs4073), IL10 (rs1800872), and TNFA (rs1800629) was conducted in 254 patients with gastric ulcer or duodenal ulcer and in 277 unrelated healthy individuals from the Bashkortostan Republic. Associations of the rs1143634C allele and the C/C genotype of the IL1B gene with PUD in ethnic Bashkirs have been revealed.
