Factor V (his 1299 arg) in Turkish patients with venous thromboembolism

A new factor V gene polymorphism (His 1254 Arg) present in subjects of african origin mimics the R2 polymorphism (His 1299 Arg)

Factor V Leiden prevalence in venous thromboembolism patients.

BACKGROUND Recent findings have demonstrated a high frequency of activated protein C resistance in patients suffering from deep venous thrombosis (DVT). This abnormality has been related to a mutation in the factor V gene (at nucleotide position 1,691, guanine to adenine [G-->A] substitution). AIM To assess the frequency of the mutation in unselected inpatients with a proved DVT. To study the...

Factor V Leiden, MTHFR C677T and Prothrombin Gene Mutation G20210A in Iranian Patients with Venous Thrombosis

Background: Factor V Leiden, Prothrombin gene (G20210A) and MTHFR (C677T) polymorphism are the main biomarkers for evaluation of tendency for venous thromboembolism. We aimed to investigate the frequency of mutations in factor V Leiden, Prothrombin G20210A and MTHFR C677T and identify the genetic status for these mutations in patients with venous thrombosis. Methods: This study was carried out...

Frequency of Factor II G20210A and Factor V Leiden Mutations in Algerian Patients with Venous Thromboembolism

Several inherited polymorphisms are associated with the risk of venous thrombosis, including mutation at codon 506 of the factor V gene and mutation at position 20210 of the prothrombin gene. The aim of this study was to determine the frequency of factor II G20210A and factor V Leiden mutations in Algerian patients with venous thromboembolism disease. In this study, genotyping for factor V Leid...

FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY

Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...
