Detection of an Ala601Thr mutation of plasminogen gene in 3 out of 36 Korean patients with deep vein thrombosis.

چکیده
Plasminogen is a key proenzyme in the fibrinolytic and thrombolytic systems. Congenital deficiency of plasminogen and molecular abnormality of plasminogen (dysplasminogenemia) have been reported in association with the thrombotic tendency in human. In dysplasminogenemia, the level of immunoreactive plasminogen is normal, although the functional activity is reduced. Human plasminogen gene spans about 52.5 kb of DNA and consists of 19 exons. Three types of mutations (Ala601Thr, Val355Phe, and Asp676Asn) have been described in dysplasminogenemia. In this study, we measured the plasminogen activity in patients with deep vein thrombosis and analyzed the DNA sequence to detect three point mutations (Ala601Thr, Val355Phe and Asp676Asn) in patients with hypo/dysplasminogenemia. Dysplasminogenemia was identified in 3 (8.3%) of unrelated 36 patients with deep vein thrombosis and the Ala601Thr mutation was detected in all three patients with dysplasminogenemia. In conclusion, dysplasminogenemia is not rare in deep vein thrombosis, which suggests a risk factor for the thrombosis in Korean population.

Treatment of deep vein thrombosis from Iranian traditional medicine and modern medicine points of view: comparative study
Background and objectives: Recently, deep vein thrombosis (DVT) has remained a major cause of morbidity and death. DVT is a serious public health issue and can be complicated by pulmonary embolism and stroke leading to high economic burden. Disease etiologies may include protein C deficiency, protein S deficiency, factor V Leiden gene mutation, prothrombin gene 20210A mutation,...

Background: Behcet’s disease (BD) is a multisystemic inflammatory disease with unknown origin characterized by recurrent oral aphtous ulcers, genital, ocular and skin lesions. A single point mutation 1691G to A in the factor V gene increases the risk of venous thrombosis. This study designed to determine factor V Leiden mutation in Behcet’s disease, and to find out it's relationship with the cl...

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...
