Objective To study the relationship between phosphodiesterase 4D (PDE4D) gene rs966221 single nucleotide polymorphisms (SNPs) and ischemic stroke (IS) in Guangxi Zhuang population.Methods One hundred and one IS patients from Guangxi Zhuang Autonomous Region served as IS pgroup and 104 healthy subjects undergoing physical ecamination served as control group in this study.Their PDE4D gene rs966221 SNPs were detected by SNaPshot technique.The genotypes and frequencies of alleles were compared between the two groups and the relationship between PDE4D gene rs966221 SNPs and IS was analyzed.Results No significant difference was found in the GG,GA,AA genotypes and in the frequencies of G and A alleles between the two groups (0.99％ vs 3.85％,29.70％ vs 21.15％,69.31％ vs 75.00％,P＞0.05;15.84％ vs 14.42％,84.16％ vs 85.58％,P＞0.05).Univariate and multivariate logistic regression analysis showed that the PDE4D gene rs966221 SNPs were not related with the risk of IS in dominant AA vs GG+GA,recessive GG vs AA+GA and additive GG vs AA genetic models (P＞0.05).Conclusion The PDE4D gene rs966221 SNPs are not related with IS in Guangxi Zhuang population.%目的 探讨广西壮族人群磷酸二酯酶4D(PDE4D)基因rs966221位点单核苷酸多态性与缺血性脑卒中(IS)发病的关系.方法 采用病例-对照研究设计,运用SNaPshot技术对101例广西壮族IS患者(IS组)及同期104例健康体检者(对照组)的PDE4D基因rs966221位点单核苷酸多态性进行检测,比较2组各基因型及等位基因频率,并进行相关性分析.结果 IS组与对照组PDE4D基因rs966221位点GG、GA、AA基因型(0.99％ vs 3.85％,29.70％ vs 21.15％,69.31％ vs 75.00％)及G、A等位基因频率(15.84％ vs 14.42％,84.16％ vs 85.58％)比较,差异无统计学意义(P＞0.05).单因素及多因素logistic回归分析显示,在显性(AA vs GG+ GA)、隐性(GG vs AA+GA)和加性(GG vs AA)3种遗传模型下,PDE4D基因rs966221位点单核苷酸多态性与IS患病风险均无关联(P＞0.05).结论 广西壮族人群PDE4D基因rs966221位点单核苷酸多态性与IS发病不相关.
