Methylmalonic acid (MMA) (conjugate base methylmalonate) is a dicarboxylic acid that is a C-methylated derivative of malonate.. The coenzyme A linked form of methylmalonic acid, methylmalonyl-CoA, is converted into succinyl-CoA by methylmalonyl-CoA mutase, in a reaction that requires vitamin B 12 as a cofactor.

The coenzyme A linked form of methylmalonic acid, methylmalonyl-CoA, is converted into succinyl-CoA by methylmalonyl-CoA mutase, in a reaction that requires vitamin B 12 as a cofactor. This test measures the amount of methylmalonic acid (MMA) in the blood or urine. High levels of MMA can be a sign of a vitamin B12 deficiency. The test is also usually included as part of a newborn screening to check for a rare genetic disorder. Chronically high levels of methylmalonic acid are associated with at least 5 inborn errors of metabolism, including Malonyl CoA decarboxylase deficiency, Malonic Aciduria, Methylmalonate Semialdehyde Dehydrogenase Deficiency, Methylmalonic Aciduria and Methylmalonic Aciduria Due to Cobalamin-Related Disorders.

Symptoms of the disorder can range from mild to severe and may include vomiting, dehydration, developmental delays, and intellectual disability. Left untreated, it can cause life-threatening complications.
