摘要
目的:进行三磷酸腺苷结合盒转运体A1(ATP binding cassette transporter A1,ABCA1)基因多态性(single nucleotide polymorphisms,SNPs)与下肢动脉粥样硬化(lower extremity atherosclerotic disease,LEAD)的关联分析。方法:收集福建省闽南地区630例体检者(314例LEAD者和316例正常者)的临床资料及外周血;采用Sequenom MassArray系统对该人群的ABCA1基因9个单核苷酸多态性(single nucleotide polymorphisms,SNPs)位点进行检测。结果:9个SNP位点中,rs2980083位-点不符合Hardy-Weinberg平衡,分析中舍去;rs2066714与rs2066715,rs1800976与rs2246293,rs2246293与rs2980083,rs1800976与rs2980083等4组位点之间存在明显的连锁不平衡(D′>0.9,r~2>1/3),对其构建的6种单倍型在两组的分布无统计学差异(P>0.05);该8个SNP位点的基因型统计在病例对照分析中的分布频率未见显著差异(P>0.05),基因logistic回归分析未显示有患病风险。结论:闽南汉族人群ABCA1基因rs10124755、rs2980083、rs1800976、rs4149341、rs2066714、rs2066715、rs2066716、rs2230808、rs2246293多态性可能与LEAD的遗传易感性无关。
Objective To analyze the association between single nucleotide polymorphisms(SNPs) of ATP binding cassette transporter Al gene(ABCAl) and lower extremity atherosclerotic disease(LEAD).Methods The clinical data and peripheral blood were collected from 630 participants(314 LEAD cases and 316 normal controls) in Han population of Minnan.The 9SNP genotypes in the ABCAl gene were detected by Sequenom MassArray.Results rs2980083 wasn't in further analysis because the genotype distribution of rs2980083 wasn't in accordance with Hardy-Weinberg equilibrium.Obvious linkage disequilibrium was found between rs2066714 and rs2066715,between rsl800976 and rs2246293,between rs2246293 and rs2980083,and between rs 1800976 and rs2980083(D'>0.9,r2>1/3).There were no significant differences(P>0.05) in 6haplotypes of ABCAl gene groups between LEAD cases and normal groups.No significant differences(P>0.05) were observed in frequency distribution between LEAD cases and normal groups in 8 SNPs from genotype statistics.There was no onset risk of LEAD from gene logistic regression analysis.Conclusions The SNPs of rsl0124755,rs2980083,rsl800976,rs4149341,rs2066714,rs2066715,rs2066716,rs2230808,rs2246293 might not be associated with the susceptibility of LEAD in this community-based population.
