Mitochondrial phosphoenolpyruvate carboxykinase deficiency

Abstract
The sibling of a patient in whom a diagnosis of phosphoenolpyruvate carboxykinase had been made developed a similar clinical illness with liver failure. However the activity of phosphoenolpyruvate carboxykinase in leucocytes and fibroblasts was normal. Phosphoenolpyruvate carboxykinase is not the primary defect in this family.
