The mitochondrial respiratory chain and the fatty acid oxidation cycle are theoretically interdependent on each other for normal function. We describe a patient with complex I deficiency who had clinical and biochemical features of long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency including liver failure, cardiomyopathy, and consistent urine organic acid pattern. Patients with features of either a respiratory chain or fatty acid oxidation disorder should have the defect characterized biochemically because of the implications with respect to potential therapy and genetic counseling.
