Abstract:
Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome among Kazakh and Han ethnicities in Xinjiang.Methods PCR-RFLP was used to detect 802 subjects' lipoprotein lipase Hind Ⅲ and S447Xgenotypes (including 201 controls and 200 metabolic syndrome patients in Kazakh and Han ethnicities, respectively). Results (1) Frequencies of H + H-/H-H- genotype (32.50% vs.47.76%), H- allele( 18.00% vs. 28.86%), SX/XX genotype (8.00% vs. 22.39%) and X allele (4.00%vs. 12.44% ) for metabolic syndrome in Hah ethnicity were all significantly lower than those in controls (P＜ 0.01 ). (2) The frequencies of H + H-/H-H- genotype (33.50% vs. 46.80% ), H- allele (22.00% vs. 28.60%), SX/XX genotype (10.50% vs. 22.90%) and X allele (5.50% vs. 12.44% ) in patients with metabolic syndrome in Kazakh were all significantly lower than those for controls (P＜0.01). (3) The frequencies of lipoprotein lipase gene Hind Ⅲ and S447X genotypes and alleles in Kazakh were not significantly different from Han (all P＞0.05). (4)The levels of waist circumference, systolic blood pressure, diastolic blood pressure, triglyceride and FPG in H + H-/H-H- and SX/XX genotype were significantly lower than those in H + H + and SS genotype.HDL-C was significantly higher than that in H + H + and SS genotype (P＜0.05). (5) The frequencies of H + H + and SS genotype increased along with the increase in number of metabolic syndrome component. Conclusion The lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms were associated with metabolic syndrome risk in Kazakh, and H + H-/H-H- genotype, H- allele, SX/XX genotype and X allele might have served as protective factors of metabolic syndrome. H + H-/H-H- and SX/XX genotype seemed to have had beneficial effects for all the metabolic syndrome components, and the frequencies of H + H + and SS genotype were increasing along with the increase of number in the metabolic syndrome components.
