The serotonergic system has been hypothesized to contribute to the biological susceptibility to type 2 diabetes mellitus (T2DM) and body-mass index (BMI) categories. We investigate a possible association of 5-HTTLPR polymorphism (L and S alleles) in the promoter region of the serotonin transporter gene (SLC6A4) with the development of T2DM and/or higher BMI by analyzing a sample of 138 individuals diagnosed with T2DM and 172 unrelated controls from the Mexican general population. In the total sample genotypes were distributed according to Hardy-Weinberg equilibrium, and S allele frequency was 0.58. There was no statistical association between 5-HTTLPR polymorphism and the development of T2DM in this Mexican population sample (p = 0.12). Nevertheless, logistic regression analysis of the L allele and increased BMI disclosed an association, after adjusting for age, sex and T2DM (p = 0.02, OR 1.74, 95% CI: 1.079-2.808).
血清素能系统被假设与 2 型糖尿病(T2DM)和体重指数(BMI)类别中的生物易感性有关。我们通过分析来自墨西哥普通人群的 138 名被诊断患有 T2DM 的个体和 172 名无关对照者的样本,研究了 5-HTTLPR 多态性(启动子区域的 L 和 S 等位基因)在血清素转运蛋白基因(SLC6A4)中与 T2DM 和/或更高 BMI 发展的可能相关性。在总样本中,基因型符合哈迪-温伯格平衡,S 等位基因频率为 0.58。在这个墨西哥人群样本中,5-HTTLPR 多态性与 T2DM 的发展之间没有统计学关联(p = 0.12)。然而,在调整年龄、性别和 T2DM 后,对 L 等位基因和增加的 BMI 的逻辑回归分析显示出相关性(p = 0.02,OR 1.74,95%CI:1.079-2.808)。
