Meta Analysis
Polymorphisms in platelet glycoprotein 1balpha and factor VII and risk of ischemic stroke: a meta-analysis.
Platelets and components of the coagulation cascade are known to be instrumental in the pathogenesis of arterial occlusive disorders. The aim of this meta-analysis is to test the hypothesis that genetic variation in the platelet glycoprotein 1balpha and Factor VII genes influence the occurrence of ischemic stroke. All genetic association studies that examined the R353Q (rs6046) polymorphism of the Factor VII gene and 2 polymorphisms of the platelet glycoprotein (1balpha) gene (Thr/Met rs6065 and Kozak sequence -5 C/T rs2243093) in relation to ischemic stroke were examined. ⋯ This analysis provides strong evidence that the Factor VII R353Q gene polymorphism is not associated with ischemic stroke, that the Thr/Met polymorphism of GP1balpha is associated with ischemic stroke in a dominant genetic model, and that the Kozak sequence polymorphism of GP1balpha may be close to another causative locus that is associated with ischemic stroke.
