Mitochondrial Oxidative Phosphorylation Disorder, also known as oxphos - [oxidative phosphorylation] diseases, is related to lactic acidosis and leigh syndrome. An important gene associated with Mitochondrial Oxidative Phosphorylation Disorder is MTFMT (Mitochondrial Methionyl-TRNA Formyltransferase). Affiliated tissues include liver and skeletal muscle, and related phenotype is Strongly decreased CFP-tsO45G cell surface transport.
