Abstract

Mutations in Sco2, a protein involved in copper trafficking to the terminal enzyme of the respiratory chain, cytochrome c oxidase, results in infantile hypertrophic cardioencephalomyopathy. We have recently shown that copper-histidine (Cu-his) supplementation of Sco2-deficient myoblasts rescues COX activity in vitro. Here, we report a patient with SCO 2 mutations and with resolution of severe hypertrophic cardiomyopathy. Weighing up the evidence, the most likely explanation for the improved cardiac function in this patient was the subcutaneous application of Cu-his.
