Methylenetetrahydrofolate Reductase Polymorphisms in Iranian Patients with Glanzmann’s Thrombasthenia
Background: The most common polymorphisms identified in the Methylenetetrahydrofolate reductase (MTHFR) gene, C677T and A1298C lead to defective activity of this enzyme and increase the risk of venous and arterial thrombosis. There are limited investigations regarding the effects of thrombogenic polymorphisms on the clinical phenotypes of rare hereditary hemorrhagic disorders like Glanzmann's t...
متن کاملIs hyperhomocysteinaemia a risk factor for recurrent venous thrombosis?
Several studies have shown a relation between hyperhomocysteinaemia and arterial vascular disease. We looked at the association between hyperhomocysteinaemia and venous thrombosis which could be clinically important as hyperhomocysteinaemia is easily corrected by vitamin supplementation. We studied 185 patients with a history of recurrent venous thrombosis and 220 controls from the general popu...
متن کاملThe End of a Long Debate: Methylenetetrahydrofolate Reductase Gene Polymorphisms do not Increase Thrombosis Risk.
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...
متن کاملMethionine synthase A2756G and methylenetetrahydrofolate reductase A1298C polymorphisms are not risk factors for idiopathic venous thromboembolism.
Hyperhomocysteinemia is a defined risk factor for venous thromboembolism (VTE). Several polymorphisms of genes encoding for enzymes acting in the remethylation pathway of homocysteine metabolism, ie, methionine synthase (MS) A2756G, methylenetetrahydrofolate reductase (MTHFR) C677T and MTHFR A1298C, can cause increased homocysteine levels particularly in patients with deficiencies of folic acid...
متن کاملMethylenetetrahydrofolate reductase gene polymorphisms in Burkina Faso.
In Burkina Faso, the levels of plasma homocysteine (Hcy) are lower and the methionine loading tests suggest a more effective Hcy metabolism [1,2]. We found a relevant difference in the allele frequencies of C677T: T 7.7% in the young and 3.3% in old subjects respectively (see Table 1). Frequencies of C677T genotypes in old and young individuals were in Hardy Weinberg equilibrium (HWE). The diff...
