normal hemostasis requires balanced regulation of prothrombotic and antithrombotic factors. inherited alteration of factor v and prothrombin gene, the g20210a mutation, increases the resistance of factor v to degradation and booster production of prothrombin respectively. these alterations can increase hypercoagulability leading to thrombotic consequences. we aimed to assess the frequencies of ...

We read the article by Ozturk et al. [1], in which they reported the frequency of some thrombophilic mutations in eastern Turkey. The authors have defined single nucleotide gene variations of factor V Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T as thrombophilic mutations. However, as current scientific data do not support an increased risk of thrombosis in...

This study was conducted to investigate the association of maternal and/or fetal factor V Leiden (FVL) and G20210A prothrombin mutation with HELLP syndrome. FVL and G20210A prothrombin mutation were determined using PCR. Sixty-three pregnant women, 36 of them diagnosed with HELLP syndrome, were included in the study. Overall, 68 children were born as a result of these pregnancies and blood samp...

OBJECTIVE To investigate the correlation between prothrombin G20210A polymorphism and the risk for idiopathic sudden sensorineural hearing loss (ISSNHL) using Meta-analysis methodology. METHODS Databases, including PUBMED, EMBASE, Cochrane Library and CBM, were searched to collect the case control studies on the correlation between prothrombin G20210A polymorphism and idiopathic sudden sensor...

The 2 most common genetic polymorphisms that predispose to a first episode of venous thromboembolism (VTE) are factor V Leiden (FVL) and prothrombin G20210A. However, the effect of these polymorphisms on the risk of recurrent VTE is unclear. We performed a meta-analysis to obtain best estimates of the relative risk of recurrent VTE associated with these genetic polymorphisms. Electronic and man...

Risk factors for venous thrombosis in adults are the prothrombin G20210A and the factor V (FV) G1691A mutations and hereditary deficiencies of protein C, protein S and antithrombin. However, data are limited on the relevance of these risk factors for thrombosis in children and adolescents. We therefore investigated 261 patients aged 0 to 18 (median 5.7 years, 48% male) with venous thrombosis an...

BACKGROUND Various studies have demonstrated that factor V Leiden (FVL) and G20210A prothrombin mutation contribute to the risk of Budd-Chiari syndrome (BCS), while other studies provided conflicting findings. In order to derive more precise estimations of the relationships, a meta-analysis was performed. METHODS Eligible articles were identified through search of databases including Pubmed, ...

BACKGROUND Factor V Leiden (FVL) and prothrombin gene (G20210A) mutations are known to be associated with venous thromboembolism. Several studies have shown an association of these mutations with hepatic venous outflow tract obstruction (HVOTO). We studied the prevalence of these mutations among patients with HVOTO in northern India in comparison with healthy population. METHODS Genomic DNA f...

BACKGROUND G20210A prothrombin mutation has been associated with high prothrombin levels and an increased risk of venous thrombosis. The role of this common polymorphism, as well as that of prothrombin levels, in determining the risk of arterial disease is still somewhat controversial. METHODS AND RESULTS We determined the prevalence of the G20210A mutation and prothrombin activity in 660 ind...

BACKGROUND A single base pair mutation in the prothrombin gene has recently been identified that is associated with increased prothrombin levels. Whether this mutation increases the risks of arterial and venous thrombosis among healthy individuals is controversial. METHODS AND RESULTS In a prospective cohort of 14 916 men, we determined the prevalence of the G20210A prothrombin gene variant i...
