Purinergic receptor P2Y, G-protein coupled, 12 gene variants and risk of incident ischemic stroke, myocardial infarction, and venous thromboembolism.

Recent data have implicated a haplotype of the purinergic receptor P2Y, G-protein coupled, 12 gene (P2RY12), as potential risk determinant for atherothrombosis. However, to date, no prospective, genetic-epidemiological data are available. Using DNA samples collected at baseline in a prospective cohort of 14,916 initially healthy American men, we examined the possible association of P2RY12 genetic variants, in particular a haplotype H2 (constituted by dbSNP rs10935838, rs2046934, rs5853517, and rs6809699) amongst 708 white males who subsequently developed a thromboembolic event (incident myocardial infarction (MI), ischemic stroke, or deep venous thromboembolism/pulmonary embolism (DVT/PE)) and amongst an equal number of age- and smoking-matched white males who remained free of reported vascular disease during follow-up (controls). The P2RY12 gene variants tested were in linkage disequilibrium. The haplotype H2 distribution was significantly different between the DVT/PE cases (12%) and their matched controls (21%), p-permuted=0.02. In an adjusted conditional logistic regression analysis, the haplotype H2 was significantly associated with a lower risk of incident DVT/PE as compared to the reference haplotype H1 (odds ratio=0.50, 95% CI=0.27-0.93, p=0.028). However, we found no evidence for an association of the P2RY12 variants or the haplotype H2 with incident MI or ischemic stroke. The present investigation provides evidence for an association of the P2RY12 haplotype H2 with lower risk of DVT/PE; however these findings require replication in other well-designed studies.[1]
