摘要
目的探讨中国北方地区汉族人群5-脂氧合酶激活蛋白(ALOX5AP)基因和白介素-1A(IL-1A)基因多态与缺血性脑卒中(Is)的相关性。方法采用病例一对照研究,检测构建ALOX5AP基因单倍型HapA的4个位点:SG13S25、SG13S32、SG13S89、SG13S114和IL-1A基因一889位点在对照组、IS组及IS亚组中多态的分布。结果ALOX5AP基因SG13S114位点AA基因型可能是血栓性脑梗死独立的风险因素(OR=1.479,95%CI1.024~2.135,P=0.037),且其风险性主要来源于A等位基因(OR=1.313,95%CI1.017—1.693,P=0.036);IL-1A基因-889位点T等位基因可能是血栓性脑梗死的易患等位基因(OR=1.540,95%CI1.075~2.204,P:0.023)。HapA单倍型和IS没有相关性,GCGA单倍型可能是Is的危险单倍型(OR=1.683,95%CI1.138—2.487,P=0.008)。同时携带ALOX5AP基因GCGA单倍型和IL-1A-889T等位基因的个体患IS的风险性显著增加(OR=1.608,95%CI1.607~2.423,P=0.022)。结论ALOX5AP基因、IL-1A基因的多态与IS具有相关性,二者的协同作用可显著增加IS的患病风险。
Objective To investigate the association of polymorphisms of 5-1ipoxygenase activating protein (ALOXSAP) gene and interleukin-lA (IL-1A) gene with ischemic stroke (IS) in Han population in northern China region. Methods Four SNPs of SG13S25, SG13S32, SG13S89, SG13Sl14 in HapA haplotype of ALOXSAP gene and a SNP (nucleotide 889) at the promoter region in IL-1A were genotyped in control group, IS group and IS subgroups by using PCR-RFLP and MALDI-TOF methods. Results SG13Sl14 AA genotype in ALOXSAP gene indicated to be an independent risk factor of thrombotic cerebral infarction ( OR = 1. 479,95 % CI 1. 024--2. 135, P = O. 037), and A allele at this SNP particularly showed a correlation with the risk ( OR = 1. 313, 95% C1 1. 017--1. 693, P =0. 036). IL-1A - 889 T allele might be a susceptible allele related to thrombotic cerebral infarction (OR = 1. 540, 95% C1 1. 075--2. 204,P = 0. 023). There was no correlation of HapA haplotype of ALOXSAP with IS but G-C-G-A haplotype might be an "at-risk" haplotype of IS ( OR = 1. 683,95 % CI 1.138--2. 487, P = 0. 008 ). The individuals who carried ALOXSAP G-C-G-A haplotype and IL-1A - 889 T allele showed significantly increased risk of IS ( OR = 1.608,95% CI 1.607--2.423,P=0.022). Conclusion ALOXSAP and IL-1A gene polymorphisms correlate with IS and they can have synergistic effect to confer higher risk for IS.
