This study reports that patients with neonatal adrenoleukodystrophy and Zellweger syndrome excrete a very peculiar pattern of organic acids. Dicarboxylic acids with an even number of carbon atoms (adipic, suberic, sebacic, 2- and 3-hydroxy-sebacic, hexadecanedioic), as well as with an odd number of carbon atoms (pimelic, azelaic, un-, tri-, and pentadecanedioic) were found in excess in the urines of six patients with neonatal adrenoleukodystrophy and one with Zellweger syndrome. The accumulation of dicarboxylic acids, reflecting an impairment of their beta-oxidation in mitochondria and/or peroxisomes, thus appears as an additional useful marker of these peroxisomal diseases.
