Alpha-ketoadipic aciduria, a new inborn error of lysine metabolism; biochemical studies.
Investigation of a psychomotorically retarded girl showed excretion of abnormal amounts of alpha-ketoadipic acid, alpha-hydroxyadipic acid, alpha-aminoadipic acid, 1,2-butenedicarboxylic acid and elevation of plasma alpha-aminoadipic acid levels.  The identity of these metabolities was established by various methods.  The excretion of alpha-aminoadipic acid correlated to the lysine intake.  Degradation studies with cultured fibroblasts indicate a defect in the oxidative decarboxylation of alpha-ketoadipic acid (see Clin. Chim. Acta, 58 (1975) 271.
