title: Glutamate dehydrogenase deficiency in patients with olivopontocerebellar atrophy.
abstract: Deficiency of glutamate dehydrogenase appears to be associated with a chronic progressive degenerative disorder manifesting parkinsonian extrapyramidal features, ataxia, supranuclear oculomotor dysfunction, a peripheral neuropathy and, in some cases, amyotrophy. The clinical features resemble those of the Dejerine-Thomas type of olivopontocerebellar atrophy. The data suggest autosomal dominant inheritance with low penetrance. Measurement of leukocyte glutamate dehydrogenase should be routinely performed in the evaluation of newly diagnosed or atypical cases of parkinsonism.
