OMIM®: 57 Infantile mitochondrial myopathy due to reversible COX deficiency is a rare mitochondrial disorder characterized by onset in infancy of severe hypotonia and generalized muscle weakness associated with lactic acidosis, but is distinguished from other mitochondrial disorders in that affected individuals recover spontaneously after 1 year of age (summary by Mimaki et al., 2010). See also transient infantile liver failure (LFIT; 613070), which is a similar disorder. (500009) (Updated 08-Dec-2022) MalaCards based summary: Mitochondrial Myopathy, Infantile, Transient, also known as mitochondrial myopathy with reversible cytochrome c oxidase deficiency, is related to mitochondrial complex iv deficiency, nuclear type 1 and myopathy, and has symptoms including weakness and facial paresis. An important gene associated with Mitochondrial Myopathy, Infantile, Transient is MT-TE (Mitochondrially Encoded TRNA-Glu (GAA/G)), and among its related pathways/superpathways are Metabolism and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. Affiliated tissues include liver, skeletal muscle and skin, and related phenotypes are muscle weakness and myopathy Orphanet: 58 A rare, genetic, mitochondrial oxidative phosphorylation disorder characterized by a potentially life-threatening, severe myopathy manifesting in the neonatal to early infantile period, followed by marked, spontaneous improvement of muscular function by early childhood. Associated biochemical findings include lactic acidosis and a transient, marked decrease in respiratory chain activity. |
