摘要: 目的 研究瘦素受体(LepR)基因Lys656Asn多态性与血三酰甘油水平的相关性。 方法 聚合酶链反应-单链构象多态性(PCR-SSCP)方法测定无亲缘关系,且有完整临床资料的232例上海地区中国人群的LepR基因Lys656Asn多态性的基因型(包括130例单纯性肥胖患者及102例正常对照者)。 结果 肥胖组和对照组两组LepR基因Lys656Asn基因型的频率分布无显著差异。在肥胖组中,Lys656Asn变异与血三酰甘油水平相关,携带G等位基因的肥胖患者血三酰甘油水平较高(1.74±0.91 比较 0.95±0.32, P<0.05)。Logistic回归分析显示,该多态性与血三酰甘油水平独立相关(P<0.05)。 结论 LepR基因Lys656Asn多态性与上海地区中国肥胖人群血三酰甘油水平相关。

Abstract: Objective To investigate the association of Lys656Asn polymorphism in leptin receptor gene with serum triglyceride level. Methods The genotypes of Lys656Asn polymorphism in LepR gene were determined by polymerase chain reaction- single strand conformation polymorphism (PCR-SSCP) assay in 232 unrelated subjects of Shanghai Chinese population (including 130 subjects with simple obesity and 102 normal controls). The clinical data were also analyzed. Results No significant difference of genotype frequency of Lys656Asn polymorphism in LepR gene was observed between obese and non-obese group. In obese group, "G" Allele was associated with increased triglyceride level (1.74±0.91 vs 0.95±0.32, P<0.05). Logistic regression analysis showed that this gene polymorphism was independently associated with serum triglyceride level (P=0.026). Conclusion Lys656Asn variant in LepR gene is associated with serum triglyceride level in Shanghai Chinese obese population.
