The BCAAs undergo transamination that is catalyzed by the branched-chain aminotransferase (BCAT) and requires α- ketoglutarate, leading to the production of the α-ketoacids KIC, KMV, and KIV. The classic presentation occurs in the neonatal period with developmental delay, failure to thrive, feeding difficulties, and maple syrup odor in the cerumen and urine, and can lead to irreversible neurological complications, including stereotypical movements, metabolic decompensation, and death if left untreated.
