8C73.0 Autosomal recessive cardiomyopathy or ophthalmoplegia

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Autosomal recessive cardiomyopathy and ophthalmoplegia is a childhood-onset disease characterised by progressive external ophthalmoplegia, mild facial and proximal limb weakness, and severe cardiomyopathy. Muscle biopsies show ragged-red and cytochrome C oxidase-negative fibres; the activities of several complexes in the electron-transport chain are decreased. The combination of progressive external ophthalmoplegia, cardiomyopathy, and multiple mtDNA deletions is thought to be due to a defect of communication between the nuclear and mitochondrial genomes.
