Abstract

Background: The fibrinogen receptor is an integrin on the platelet surface and is shaped from two types of glycoprotein (GP) subunits, GPIIb and GPIIIa. Membrane glycoprotein IIb/IIIa plays an important role in platelet function. The gene encoding the glycoprotein IIIa shows a common polymorphism, PLA2 that increases the binding of the receptor to fibrinogen and enhances the platelet aggregation. The clinical impact of PLA2 polymorphism has been studied in some diseases, but the definition of its exact role on venous thromboembolism complications has been challenging. The present systematic review aimed to clarify the association of PLA2 polymorphism and venous thromboembolism. Main text: In this study, Electronic databases including PubMed, Embase, Scopus, Web of Science, and Cochrane Library were searched. All the assessed studies focused on the relationship between PLA2 polymorphism and venous thromboembolism. Five studies were eligible for systematic review. One study revealed a significant correlation between PLA2 polymorphism and venous thromboembolism. PLA2 polymorphism was associated with deep vein thrombosis in one study and pulmonary thromboembolism in another one. Conclusion: The published data supported the hypothesis that having the PLA2 polymorphism of GPIIIa may be a risk factor for venous thromboembolism, but the association cannot be concluded; it needs more clinical investigation. © 2019, The Author(s).
