Combined Oxidative Phosphorylation Deficiency 33; Coxpd33


COXPD33 is an autosomal recessive multisystem disorder resulting from a defect in mitochondrial energy metabolism. The phenotype is highly variable, ranging from death in infancy to adult-onset progressive external ophthalmoplegia (PEO) and myopathy. A common finding is cardiomyopathy and increased serum lactate (summary by Feichtinger et al., 2017).For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (OMIM ).
