title: Malonyl coenzyme A decarboxylase deficiency.
abstract: A patient is described with a deficiency of the mitochondrial enzyme, malonyl CoA decarboxylase - an inborn error of metabolism not recognized previously. The enzyme defect was first suspected because of persistent excretion of malonic and methylmalonic acids in urine in a child with repeated episodes of vomiting, some requiring hospitalization. Disturbances of lipid metabolism were demonstrated.
