factor v leiden deficiency is the most common hereditary hypercoagulable disease in the united states and involves 5% of the caucasian population. up to 30% of patients who present with deep vein thrombosis (dvt) or pulmonary thromboembolism present with this condition. this is a case report of a 36-year-old man who experienced one episode of dvt within the previous year and was admitted to our...

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...

Background—Homozygous or double heterozygous factor V Leiden and/or prothrombin G20210A is a rare inherited thrombophilic trait. Whether individuals with this genetic background have an increased risk of recurrent venous thrombosis is uncertain. Methods and Results—A case-control design within a large cohort of families with thrombophilia was chosen to calculate the risk of recurrent venous thr...

BACKGROUND Homozygous or double heterozygous factor V Leiden and/or prothrombin G20210A is a rare inherited thrombophilic trait. Whether individuals with this genetic background have an increased risk of recurrent venous thrombosis is uncertain. METHODS AND RESULTS A case-control design within a large cohort of families with thrombophilia was chosen to calculate the risk of recurrent venous t...

BACKGROUND AND OBJECTIVES The prothrombin G20210A mutation and factor V Leiden have been found to be associated with an increased risk of venous thrombosis, but the reported prevalences of the prothrombin gene variant both in the normal population and in patients with deep venous thrombosis (DVT) vary greatly in the literature. Moreover, the influence of oral contraceptives (OC) on thrombotic e...

background: factor v g1691a (fv leiden), fii ga20210, and methylenetetrahydrofolate reductase (mthfr) c677t mutations are the most common genetic risk factors for thromboembolism in the western countries. however, there is rare data in iran about cerebral venous and sinus thrombosis (cvst) patients. the aim of this study was to evaluate the frequency of common genetic thrombophilic factors in c...

Normal maternal adaptation to pregnancy significantly increases the risk for thrombus formation. Inherited thrombophilias further increase risk for deep venous thrombosis and adverse outcome in pregnancy. Factor V Leiden mutation is the most common inherited thrombophilia, occurring in approximately 5% of the White and 1% of the Black populations. Nurses should be knowledgeable about screening ...

AIM Factor V Leiden (R506Q) mutation is the most commonly observed inherited genetic abnormality related to vein thrombosis. Lebanon has one of the highest frequencies of this mutation in the world with a prevalence of 14.4% in the general population. The aim of this study is to define risk factors including inherited genetic abnormalities among Lebanese patients with lower extremity deep vein ...

Deficiency of the naturally occurring anticoagulant proteins, such as antithrombin, protein C and protein S, and activated protein C resistance due to the factor V Leiden gene mutation is associated with inherited thrombophilia. So far, no direct comparison of the thrombotic risk associated with these genetic defects is available. In this study, we wish to compare the lifetime probability of de...
