摘要: 目的 探讨细胞间黏附分子 1 (ICAM-1) 基因单核苷酸多态性 (SNP) 与糖尿病周围神经病变 (DPN) 的相关 性。方法 选取 2013 年 6 月—2014 年 12 月我院收治的 607 例 2 型糖尿病患者, 其中 DPN 组 295 例, 非 DPN 组 312 例。采用 TaqMan 等位基因分型法测定患者 rs5498(A/G K469E)和 rs1799969(G/A R241G)基因型, 分析组间 2 个 SNPs 位点的基因型分布以及不同遗传模型对 DPN 患者发病的影响。结果 2 组 rs5498(A/G K469E)和 rs1799969 (G/A R241G) 基因型频率分布均符合 Hardy-Weinberg 平衡。非 DPN 组与 DPN 组 rs1799969 (G/A R241G) 主要以 GG 型为主, 分别为 96.8% 和 99.0%; rs5498 A/G K469E 以 AA 型和 AG 型为主(非 DPN 组: AA 48.7%, AG 39.4%; DPN 组: AA 51.5%, AG 41.7%)。2 组 rs5498(A/G K469E)和 rs1799969(G/A R241G)基因型分布和等位基因 频率比较差异无统计学意义 (P > 0.05)。遗传模型分析显示 rs5498 (A/G K469E) 显性模型 (AA+AG) /GG 和加性模型 GG/AA 中, 携带 A 等位基因与 DPN 的易感性有关(校正 OR 分别为 1.585 和 1.575, 均 P < 0.05), rs1799969(G/A R241G) 与 DPN 发病无明显关系。结论 ICAM-1 基因 SNP rs5498 (A/G K469E) 与 2 型糖尿病的 DPN 并发症相关, 携带 A 等位基因可能是一个危险因素。

Abstract: Objective To investigate the association of genetic polymorphisms of intercellular adhesion molecule 1 (ICAM-1) with diabetic peripheral neuropathy (DPN). Methods A total of 607 type 2 diabetes patients from the Affiliated Hospital of Weifang Medical University were enrolled in this study between June 2013 and December 2014. Rs5498 (A/G K469E) and rs1799969 (G/A R241G) in the ICAM-1 gene were genotyped by using TaqMan allelic discrimination in 295 patients with DPN and 312 subjects without DPN. The distribution of these two SNPs and the genetic influence of ICAM-1 gene polymorphisms on the development of DPN were conducted. Results Genotype distributions of both SNPs were coincided with Hardy-Weinberg equilibrium in the two groups. SNP rs1799969 (G/A R241G) in the ICAM-1 gene showed a high GG genotypic frequency at 96.8% (non DPN) and 99.0% (DPN) respectively. SNP rs5498 (A/G K469E) represented AA and AG genotypes. The values were AA 48.7%/AG 39.4% in non DPN group and AA 51.5%/AG 41.7% in DPN group. There were no significant differences in genotypic distributions and allele frequencies of SNPs rs1799969 (G/A R241G) and rs5498 (A/G K469E) between the patients with DPN group and patients without DPN group (P > 0.05). The dominant(AA+AG) /GG and additive (GG / AA) models of rs5498 (A / G K469E) were associated with higher risk of DPN (ORadjusted=1.585, 1.575 respectively, P < 0.05). To carry A allele was related to the susceptibility of DPN. There was no such association in genetic models of rs1799969 (G/A R241G) and DPN pathogenesis. Conclusion The present study provides evidence that SNP rs5498 E469K (A/G) in the ICAM-1 gene is associated with susceptibility of DPN, and the carrying A allele appears to be a risk of DPN
