Enzymatic dysfunction has the following consequences: [1] Methionine synthase demethylates 5-methyltetrahydrofolate, producing tetrahydrofolic acid, a cofactor in purine synthesis, and also converts homocysteine to methionine Tetrahydrofolic acid DNA synthesis impaired hematopoiesis Large, nucleated hematopoietic cells, including megaloblasts, are produced, which undergo apoptosis or are phagocytosed by macrophages Pancytopenia (including megaloblastic anemia) Methionine neuropathy [2] [5] Homocysteine endothelial damage (increases risk for cardiovascular disease) Can cause secondary folate deficiency Methylmalonyl-CoA mutase (converts methylmalonyl-CoA to succinyl CoA) Accumulation of methylmalonyl-CoA and its precursor propionyl-CoA, as well as their associated odd-chain fatty acids, which cannot be completely metabolized Propionyl CoA replaces acetyl CoA in neuronal membranes demyelination neurological manifestations Folate deficiency also leads to low levels of tetrahydrofolic acid, causing megaloblastic anemia
