Objective: To identify the relationship between coagulation factor V (FV) gene single nucleotide polymorphisms (SNPs) and venous thromboembolism (VTE).
Methods: The FV clotting activity (FV: C) and FV antigen (FV: Ag) in plasma of VTE group (111 patients) and normal control (110 patients) were detected using one-stage clotting assay and ELISA, respectively. Five pairs of primers of the F V polymorphisms including Asp79His, Arg306The, Arg306Gly, Arg506Gln and Ile359The/His1299 Arg were synthesized and amplified by PCR.

Background And Objectives: In carriers of the factor V (FV) Leiden mutation, different trans-acting gene variants (HR2 haplotype and FV Cambridge mutation) affect activated protein C (APC) sensitivity. Among a series of FV gene variants characterized, the Asp79His polymorphism appeared to be a good candidate for the modulation of FV activity.
Design And Methods: In a group of 150 apparently healthy subjects without the FV Leiden mutation and in 55 apparently healthy subjects with mutation, genotypes of the Asp79His polymorphism and of the HR haplotype were characterized and plasma levels of FV coagulant activity and APC ratios evaluated.
