We report the clinical features, biochemical details, and treatment of the first detected cases of an inborn error of aromatic L-amino acid decarboxylase. Male monozygotic twins presented with extreme hypotonia and oculogyric crises. Concentrations of biogenic amines and their metabolites were reduced considerably both centrally and peripherally. Pterin and phenylalanine metabolism were normal. Activity of aromatic L-amino acid decarboxylase was virtually absent in a liver biopsy sample and… CONTINUE READING
