title: Metabolic myopathies.
abstract: Six glycogen storage diseases (resulting from deficiencies of acid maltase, phosphorylase, phosphofructokinase, phosphoglycerate kinase, phosphoglycerate mutase, and lactate dehydrogenase) and one mitochondrial myopathy (cytochrome c oxidase deficiency) are reviewed to illustrate: clinical heterogeneity, biochemical heterogeneity, evidence for tissue-specific and developmentally controlled isozymes, and molecular genetic studies.
