An early morning (first voided) sample is best for analysis of various OA metabolites, is more concentrated and defects of amino acid catabolism and fatty acid oxidationare more distinct.
[3] MSUD is a disorder of branched-chain amino acid catabolism, caused by a deficiency in the branched-chain [alpha]-keto acid dehydrogenase complex, which is responsible for the decarboxylation of the branched-chain amino acids (BCAA), leucine, isoleucine, and valine (Fig.
