Methionine synthase polymorphisms (MTR 2756 A>G and MTR 2758 C>G) frequencies and distribution in the Jordanian population and their correlation with neural tube defects in the population of the northern part of Jordan

Abstract excerpt

BACKGROUND: The human methionine synthase gene (MTR) is located on chromosome 1q43; it is of 105.24 kb and is made up of 33 exons. Methionine synthase is a cytoplasmic enzyme that requires methylcobalamin for activity and catalyzes the remethylation of homocysteine to methionine. In this reaction, the methyl group of 5-methyltetrahydrofolate is transferred to the enzyme bond cob(I) alamin to generate...
