BACKGROUND ABO blood type locus has been reported to be an important genetic determinant of venous and arterial thrombosis in genome-wide association studies. We tested the hypothesis that ABO blood type alone and in combination with mutations in factor V Leiden R506Q and prothrombin G20210A is associated with the risk of venous thromboembolism and myocardial infarction in the general populatio...

The polymorphism G20210A in the 3' untranslated region of the prothrombin gene is associated with an increased level of factor II activity and confers a twofold to fivefold increase in the risk for venous thromboembolism. Among Caucasian populations, the prevalence of factor II G20210A heterozygotes is 1% to 6%, whereas in non-Caucasian populations it is very rare or absent. The aim of the pres...

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...

Objective: Cerebral venous thrombosis (CVT) is an important cause of stroke, especially in young adults, that has many predisposing factors. G20210A mutation in prothrombin gene (Factor II) and G1691A mutation in Factor V Leiden (FVL) are two common hereditary causes of CVT. This study aimed to study the rate of these mutations in patients with CVT from Fars Province in southern Iran. Methods: ...

OBJECTIVES To compare the prevalence of prothrombin G20210A in patients with objectively confirmed cerebral vein or cortical vein thrombosis against healthy controls, and evaluate geographical variations. DESIGN Systematic review and meta-analysis of case control studies. METHODS We conducted a systematic review of electronic databases including MEDLINE and EMBASE. The main outcome was the ...

OBJECTIVE The aim of our study was to determine the frequency of resistance to activated protein C (APC), factor V Leiden (FVL) and the prothrombin G20210A variant in patients with colorectal cancer. METHODS 74 patients with colorectal cancer and 192 colonoscopically selected controls were prospectively investigated for the presence of APC resistance, FVL and the prothrombin G20210A variant. ...

Prothrombin gene G20210A mutation is a risk factor for the development of deep vein thrombosis. We present a 6-year-old Egyptian boy who had vomiting associated with headache and dizziness. His conscious level was normal, with neither focal neurological signs nor papilledema. Brain computed tomographic scan, magnetic resonance imaging and magnetic resonance venography (MRV) revealed thrombosis ...

kidney disease who started peritoneal dialysis in 2000. Four years later, the patient received a cadaver donor transplant from a 52-year-old woman. Surgery was performed without technical difficulties and good initial graft perfusion was observed. An immunosuppressive regimen consisting of tacrolimus, mycophenolate mofetil and steroids was initiated. The post-operative course showed persistent ...
