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 کاملRegulation of human methylenetetrahydrofolate reductase by phosphorylation.
Methylenetetrahydrofolate reductase (MTHFR) catalyzes the reduction of methylenetetrahydrofolate to methyltetrahydrofolate, the methyl donor for the conversion of homocysteine to methionine. Regulation of MTHFR activity is crucial for maintaining cellular concentrations of methionine and S-adenosylmethionine (AdoMet). Purified recombinant human MTHFR expressed in insect cells is multiply phosph...
متن کاملLong term treatment with betaine in methylenetetrahydrofolate reductase deficiency.
A girl aged 7.5 years with deficiency of 5,10-methylenetetrahydrofolate reductase was treated from early infancy with betaine, 3-6 g daily. She has slight microcephaly, moderate developmental delay, and impaired vision but there have been no obvious signs of folate deficiency. From 4 years of age, she developed an unexplained extreme increase in appetite and weight. Recent magnetic resonance im...
متن کاملBetaine for treatment of homocystinuria caused by methylenetetrahydrofolate reductase deficiency.
A 24 day old girl with homocystinuria and hypomethioninaemia caused by methylenetetrahydrofolate reductase deficiency presented with rapidly progressing encephalopathy and myopathy. An almost complete recovery was achieved by treatment with betaine.
متن کاملPrevalence of genetic polymorphisms of methylenetetrahydrofolate reductase C677T and angiotensin I-converting enzyme (insertion/deletion) in Sétif population, Algeria
The aim of the present study was to assess the frequencies of angiotensin I-converting enzyme (ACE; OMIM: 106180) and methylenetetrahydrofolate reductase (MTHFR; OMIM: 607093) polymorphisms in the Algerian population to further facilitate investigations on possible associations with various pathologies. The study was carried out on 146 apparently healthy individuals (65 males, 81 females) who w...
