Mitochondrial pyruvate carrier deficiency is an autosomal recessive metabolic disorder characterized by delayed psychomotor development. Patients present with severe lactic acidosis, normal lactate/pyruvate ratios and normal pyruvate dehydrogenase activity. Mitochondrial pyruvate carrier mediates the proton symport of pyruvate across the inner mitochondrial membrane, and plays a key role in glycolysis and gluconeogenesis.
