脂蛋白相关磷脂酶A2基因Val279Phe和Ile198Thr突变与脑梗死的相关性

目的 探讨脂蛋白相关磷脂酶A2(lipoprotein-associated phospholipase A2,Lp-PLA2)基因Val279Phe和Ile198Thr突变与江苏省汉族人脑梗死的关系.方法 纳入150例江苏省汉族人脑梗死患者和100名健康对照者,应用聚合酶链反应和变性高效液相色谱法分析Lp-PLA2基因Val279Phe和Ile198Thr突变与脑梗死之间的关系.结果 脑梗死组Val279Phe基因型和突变等位基因频率显著高于对照组(χ2分别为6.31和5.32,P均＜0.05),而Ile198Thr基因型和突变等位基因频率与对照组无显著差异(χ2分别为0.039和0.037,P均＞0.05).结论 Lp-PLA2基因Val279Phe突变可能是江苏省汉族人脑梗死的遗传学危险因素.

Correlation between Val279Phe, Ile198Thr mutation in lipoprotein-associated phospholipase A2 gene and cerebral infarction

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.
