title: Familial intermittent ataxia with possible X-linked recessive inheritance. Two patients with abnormal pyruvate metabolism and a response to acetazolamide.
abstract: Five males in one kindred suffered from intermittent ataxia and one female may have been more mildly affected. The pattern of inheritance strongly suggests X-linkage. Cerebral pathology in one case had some features of Leigh's disease. A defect in pyruvate metabolism was found in two cases. Acetazolamide gave a temporary clinical and biochemical improvement in two cases.
