Gene: [01q43/MTR] 5-methyltetrahydrofolate:L-homocysteine S-methyltransferase; tetrahydropteroylglutamate methyltransferase (methionine synthase); homocystinuria-megaloblastic anemia (due to defect in cobalamin metabolism, cbl G type; MIM:250940);
COM | Li-1996 assigned the MTR gene to 1q42.3-44. Leclerc-1996 mapped the gene to 1q43." |
FUN | The reaction catalyzed: 5-methyltetrahydrofolate + L-homocysteine = = tetrahydrofolate + L-methionine." |
