Objective To investigate the correlation between CYP2C19 gene polymorphism and elderly cerebral infarction.
Methods Two polymorphisms including rs4244285 and rs4986893 of the CYP2C19 gene were detected by gene chip technology in 72 elderly patients with acute cerebral infarction (stroke group) and 77 otherwise healthy controls. The clinical data and the polymorphism distribution of CYP2C19 were compared,and the potential association between genetic polymorphism and cerebral infarction was analyzed by Logistic regression.
Results The frequencies of rs4244285 GG (45.83% vs. 63.64%,χ 2=4.766,P=0.029) and rs4244285 A allele (34.03% vs. 22.73%,χ 2=4.695,P=0.030) were significantly higher in stroke group than in control group. There were no significant differences in the distribution of the alleles of rs4986893 or the rs4244285 GA and AA between these two groups (all P>0.05). After the conventional cerebrovascular risk factors including gender,age,body mass index,smoking,and total cholesterol were adjusted,Logistic regression analysis showed that rs4244285 A allele significantly increased the stroke risk [the additive model AA vs. GG:OR=2.564,95%CI=1.181-5.566,P=0.017;the dominant model AA/AG vs. GG:OR=2.763,95%CI=1.343-5.685,P=0.006].
Conclusion CYP2C19 genetic polymorphism may be associated with the increased risk of cerebral infarction in the elderly,although future well-designed studies with larger sample sizes are warranted.
