title: Fumaric aciduria: a new organic aciduria, associated with mental retardation and speech impairment.
abstract: Two siblings are described who present with fumaric aciduria, a hitherto unreported organic aciduria. The results of our analytical investigations using gas chromatography/mass spectrometry, and the clinical presentation of the patients, are consistent with the notion that the fumaric aciduria is caused by an inherited defect which leads to a net secretion of fumaric acid by the renal tubules.
