In a total of 543 Turkish women with RPL and 327 of their male partners (870 individuals with RPL), and a control group of 106 fertile couples (control) were analyzed for factor V leiden (FVL), factor V H1299R, factor II prothrombin G20210A, FXIII V34L, β-fibrinogen -455G>A, plasminogen activator inhibitor-1 (PAI-1), GPIIIaL33P (HPA-1 a/b L33P), methylenetetrahydrofolate reductase (MTHFR) C677T, MTHFR A1298C, ACE I/D, Apo B R3500Q, and Apo E genes.
The aim of this study was to evaluate the association of prothrombotic gene polymorphisms [factor V Leiden (FVL) 1691GA, factor VII (FVII) 10976GA, FVII HVR4, platelet membrane glycoproteins GP1BA 1018CT, GP1BA VNTR, integrin ITGB3 1565TC, integrin ITGA2 807CT and methylenetetrahydrofolate reductase (MTHFR) 677C/T], plasma factors (fibrinogen and homocysteine) and traditional risk factors with acute myocardial infarction (AMI) in 184 patients ≤ 40 years of age and 350 controls (≤ 40 years) from north India.
In a prospective study of 86 patients with polycythemia vera (43 patients) or essential thrombocythemia (43 patients), we examined the possible role of polymorphisms of platelet adhesion receptors [glycoprotein (GP) Ibalpha, GPIa, GPIIIa) and clotting factor II (prothrombin's G20210A mutation) and clotting factor V (Leiden mutation) in determining the risk of thrombotic or bleeding complications.
