Branched-Chain Amino Acids The branched-chain amino acids are called branched-chain because of their chemical structure. If left untreated, irreversible neurological damage and metabolic catastrophe ensue. Homocystinuria Maple syrup urine disease Phenylketonuria Tyrosinemia Newborns also are screened for a number of other inherited disorders, but screening varies from state to state. Treatment consists of close metabolic monitoring and dietary restriction of branched-chain amino acids. It classically manifests in the neonatal period with failure to thrive, delayed developmental milestones, feeding difficulties, and a maple syrup odor in the urine or cerumen. The underlying defect in the BCKAD complex disrupts the metabolism of branched-chain amino acids, which leads to an accumulation of branched-chain amino acids (BCAAs) in the plasma and their respective branched-chain ketoacids in the urine. This complex is responsible for the breakdown of branched-chain amino acids: It is a defect of metabolism due to abnormal activity of the branched-chain alpha-ketoacid dehydrogenase (BCKAD) complex. Maple syrup urine disease (MSUD) was first described as a rapid onset of Menkes' neurodegenerative disease in 1954.
