Abstract
To assess the association between polymorphisms of protein-activated inwardly rectifying K+ channel (GIRK4) gene and insulin resistance (IR) in Xinjiang Uygur population.A cross-sectional epidemiological survey-based case-control study was carried out, for which 1295 subjects (including 324 IR patients and 971 non-IR controls) were randomly selected. Functional region of the GIRK4 gene was sequenced for 48 randomly selected IR patients. Representative variable sites were chosen, with its association with IR assessed in 1295 Uygur subjects.rs11221497 variant was associated with IR in Uygur subjects under 50 years old (P=0.017 in genotype model, P=0.009 in dominant model). Subjects with dominant model of CC genotype have an OR of 1.833 (95%CI: 1.157-2.905) for IR.GIRK4 gene polymorphisms may be associated with IR in Uygur ethnics from Xinjiang. The CC genotype of rs11221497 variant is a risk factor for IR.
