Amino acid metabolism disorder, late-onset or intermittent forms may not always be detected by newborn screening The goal amino acid metabolism disorder long-term treatment is to maintain the plasma BCAA levels as close to normal as possible using dietary modifications including protein restriction and BCAA-free medical formula.
The plasma concentration of leucine, the most neurotoxic of the BCAA, typically guides adjustments to the dietary regimen.
Long-term control of leucine levels has been associated with intellectual and neuropsychiatric outcome in this disorder 181922 Intercurrent illnesses can result in the release of BCAAs from endogenous protein catabolism and risk for acute metabolic decompensation.
