Association of Genetic Variants in -Related Genes With Risk of Metabolic Syndrome in the Chinese Han Population.

Aims: To explore associations between polymorphisms of -related genes including , , and and Metabolic syndrome (MetS) susceptibility in the Chinese Han population.

Methods: 66 subjects with MetS and 257 control subjects were collected for inclusion in a case-control study. PCR-RFLP was used to investigate polymorphisms in the , , and genes. Elisa was used to detect the serum concentrations.

Results: Females carrying the GG and AG genotypes of rs680 ( exhibited a lower risk of MetS, compared with those harboring AA (adjusted OR = 0.388, = 0.027), while GG and AG genotypes were associated with lower fasting glucose and HbA1c. In males, the Waist-to-Hip Ratio (WHR) and the level of TG were significantly higher in GG and AG genotypes than in the AA genotype of rs680 in . Levels of HDL-c were lower in men with GG and AG genotypes compared with those carrying the AA genotype. Serum concentrations did not change among different genotypes. Finally, multifactor dimensionality reduction (MDR) analysis identified interactions between four polymorphisms: rs3741279 (), rs680 (), rs1470579 () and rs629849 ().

Conclusions: Our study suggests that -related genes including , , and genes may play pivotal roles in the development of MetS.
