The prothrombin gene mutation G20210A is a common risk factor for thrombosis and is associated with increased prothrombin levels. However, the mechanism whereby hyperprothrombinemia predisposes to thrombosis remains unclear. Because thrombin is the physiologic activator of TAFI (thrombin activatable fibrinolysis inhibitor), the precursor of an antifibrinolytic carboxypeptidase (TAFIa), we evalu...

background: inherited thrombophilic gene polymorphisms have been related to the pathogenesis of venous thromboembolism and its outcomes. considering the scarcity of data on the frequency of the thrombophilic gene polymorphisms in iranian populations, the aim of this study was to assess such polymorphisms in healthy individuals. materials and methods: this cross-sectional study was performed on ...

Prothrombin mutation G20210A, anti-phospholipid syndrome as well as iron overload has previously been shown to cause thrombotic events. The main reason for this is the involvement of these anomalies in causing hypercoagulability of the coagulation system, which frequently leads to venous and arterial thrombotic events. We report the case of a 37-year-old white female with prothrombin mutation G...

BACKGROUND AND OBJECTIVES The G20210A polymorphism in the prothrombin gene is a common cause of inherited thrombophilia. Scarce information is available about the circumstances of the heralding thrombotic manifestation at different ages. The aim of this study was to determine the risk of spontaneous or secondary venous thromboembolism (VTE) among younger and older carriers of the G20210A prothr...

Inherited prothrombotic risk factors predispose patients to thromboembolic events. In kidney transplant recipients, thrombophilia may manifest itself with venous thrombosis, microvascular occlusion, or acute rejection with major consequences for allograft survival. This is a prospective study on 165 renal allograft recipients to evaluate the contribution of genetic thrombophilic risk factors to...

OBJECTIVE To estimate the relationship between the risk of preeclampsia and two thrombophilia gene single-nucleotide polymorphisms (SNPs), the factor V G1691A SNP and the prothrombin G20210A SNP. DATE SOURCES A systematic search of the English-language literature up to November 2012 was performed using Medline and EMBASE. Search terms included "preeclampsia," "thrombophilia," "factor V Leiden...

Thrombophilias is a recognized risk factor for thrombotic events. The prothrombin variant G20210A gene mutation has been commonly examined using polymerase chain reaction (PCR). Currently, in many clinical laboratories, performing the PCR in real-time technique, which, in addition to identifying the G20210A mutation, makes possible the detection of other mutations in the 3’UTR of the prothrombi...

BACKGROUND Intrauterine growth restriction (IUGR) is a major cause of fetal morbidity and mortality during pregnancy. The role of mutation in the factor V gene, prothrombin gene, MTHFR gene, as risk factors for intrauterine growth restriction during pregnancy, is not very well known so far. MATERIALS AND METHODS This is a retrospective study of 151 pregnant women with a history of complicated...

Introduction. Cerebral venous sinus thrombosis (CVST) is a rare form of cerebrovascular disease, which may manifest clinically by a wide variety of signs and symptoms. It has been associated with multiple risk factors including genetic or acquired blood disorders, infections, and trauma. Case Report. Man of 17 years who presented with 10 days of intense global headache with nausea and vomiting ...

Frequently an inherited predisposition to thrombosis remains clinically silent until an additional environmental factor intervenes. The present study aimed to assess distribution of inherited risk factors of venous thrombosis in patients with venous thromboembolism (VTE). The prevalences of factor V Leiden (FV Leiden), prothrombin factor II G20210A (FII G20210A), C677T and A1298C of methylenete...
