Abstract

Mitochondrial trifunctional protein (MTP), an enzyme complex participating in fatty acid beta-oxidation, is the potential site of two documented defects: long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) and MTP deficiencies. LCHAD deficiency usually manifests as hypoglycemia, with hepatopathy, hypotonia, cardiomyopathy, and retinopathy. Hypoparathyroidism has been detected in a patient with MTP deficiency. We now report on a patient with LCHAD deficiency and hypoparathyroidism, evidenced by hypocalcemia, hyperphosphatemia, and a low level of parathyroid hormone, in whom the parathyroid glands could not be located after death.
