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 .
