  • Title: [Urinary phenylalanine metabolites in hyperphenylalaninemia (author's transl)].
    Author: Koepp P.
    Journal: Klin Wochenschr; 1976 Nov 01; 54(21):1047-53. PubMed ID: 994457.
    Abstract:
    Urinary phenylalanine metabolites after phenylalanine load of 4 healthy controls, 15 patients with classical phenylketonuria and 8 patients with hyperphenylalaninemic variants are measured quantitatively by gas chromatography. Statistically significant differences are found for a number of metabolites, e.g. phenylpyruvate, phenyllactate, ortho-hydroxy-phenylacetate, para-hydroxy-phenylpyruvate and para-hydroxy-phenyllactate. The results are discussed with respect to discrimination of phenylketonuria patients and patients with hyperphenylalaninemic variants and in respect to pathophysiological aspects.
