Striatal degeneration in glutaric acidaemia type II.
A girl of first cousin parents presented in the 1st year of life with a progressive neurological disease with muscle weakness and hypotonia, accompanied later by dystonia. Investigations, including gas chromatography of urine, showed no abnormality. Autopsy showed marked neuronal loss and gliosis in the putamen and globus pallidus. The activity of glutaryl-CoA dehydrogenase in cultured fibroblasts was normal, but the activity of electron transfer flavoprotein was markedly diminished. Retrospective study of urine by capillary gas chromatography/mass spectrometry showed small amounts of glutaric and other organic acids. This is the first report of striatal degeneration in association with glutaric acidaemia type II. The neuropathological changes were milder than those in glutaric acidaemia type I.
