摘要 目的:研究中国人群二甲基精氨酸二甲基氨基酸水解酶(DDAH)基因单核苷酸多态性(SNP)与冠状动脉性心脏病(coronary heart disease,CHD)的关系。方法:从山西医科大学第二医院选取冠心病患者165例和匹配的对照组192例。并记录所有研究对象的病史、体格检查等临床资料及其它流行病学资料,采取聚合酶链式反应和限制性酶切片段长度多态性分析方法(PCR-RFLP)检测各组DDAH2基因rs805305位点C/G的基因型并统计各组的基因型频率。用连接酶检测反应(LDR)-测序分型方法检测各组基因rs2272592位点G/A的基因型并统计各组的基因型频率。结果:冠心病组rs805305和rs2272592基因型频率与对照组之间相比较均无显著差异(P>0.05)。并在校正了年龄、性别、高血压史、糖尿病史、甘油三酯和胆固醇等传统危险因素的影响后,这种相关性依然不存在。结论:DDAH2基因rs805305位点C/G多态性和rs2272592位点G/A多态性可能与中国人群冠心病发病不相关。 AIM: To investigate the relationship between single nucleotide polymorphism (SNP) of dimethylarginine dimethylamino acid hydrolase (DDAH) gene and coronary heart disease (CHD) in Chinese population. METH- ODS: The polymerase chain reaction -restriction fragment length polymorphism (PCR- RFLP) and ligase detection reaction (LDR) were used to detect the genotypes of SNP rs805305 and rs2272592 in 192 controls and 165 patients with coronary heart disease (CHD). RESULTS: Both the frequency of rs805305 CG + GG or G allele and the frequency of rs2272592 GA + AA or A allele had no significant difference between CHD and control (P 〉 0.05 ). These results were independent of age, gender, hypertension, diabetes and hyperlipidemia. CONCLUSION: The rs805305 and rs2272592 polymorphism of DDAH2 gene might not be related to the coronary heart disease (CHD) in Chinese.
