| Combined oxidative phosphorylation defect type 17 is a rare, genetic, mitochondrial disorder due to a defect in mitochondrial protein synthesis characterized by infantile onset of severe hypertrophic cardiomyopathy (that occasionally progresses to dilated cardiomyopathy) associated with failure to thrive, global development delay, muscular hypotonia, elevated serum lactate and complex I deficiency in skeletal muscle biopsy. Intellectual disability, pericardial effusion and a mild cardiac phenotype have been also reported. |
