Neurology:与吸烟有关的帕金森易感基因突变

2018-01-20 zhangfan MedSci原创

研究确证了帕金森患者的部分易感基因与吸烟的相关性,该研究为帕金森生物标志物的开发提供了新途径

近日,研究人员对吸烟与个体易感性相关基因相互作用对帕金森病(PD)风险的影响进行了考察。

在法国2项以人口为基础的队列研究中,513名PD患者和1147名对照志愿者,接受289个基因,3179个单核苷酸多态性(SNPs) 研究,考察吸烟相关PD个体易感性基因。通过贝叶斯经验法(EB)筛选相关基因。对加州队列研究中(410名患者,845名对照) 筛查的9个吸烟相关PD易感基因通过标准逻辑回归和EB法进行验证。

研究考察了9个吸烟相关PD个体易感性SNPs,其中PD 风险基因RXRA基因rs4240705核苷酸与SLC17A6基因rs1900586变异与吸烟的相关性得到确证。逻辑回归显示rs4240705-G(1.66,95% CI 1.28–2.14)和rs1900586-G(1.61,95% CI 1.17–2.21)变异与吸烟相关。吸烟人群上述2个核苷酸AA纯合子的频率显著低于对照人群,而G等位基因突变频率显著提高。

研究确证了帕金森患者的部分易感基因与吸烟的相关性,该研究为帕金森生物标志物的开发提供了新途径。
