In maple syrup urine disease (MSUD; McKusik 248600), the degradation of the essential branched-chain L-amino acids leucine, valine, and isoleucine and their derived 2-oxoacids is impaired because of an inherited deficiency in branched-chain 2-oxoacid dehydrogenase complex (EC 1.
Soon after Guthrie (1) expanded newborn screening by adding galactosemia, maple syrup urine disease (MSUD), and homocystinuria to the original screening for phenylketonuria (PKU), he realized that screening would be more efficient and comprehensive if a single assay could be used to detect several disorders rather than the system of a separate bacterial assay for each disorder that he had developed.
