Mitochondriales COX3-Gen

Das mitochondriale Gen mit der offiziellen Bezeichnung MT-CO3 kodiert ein Enzym des Elektronentransportes auf der inneren Mitochondrienmembran. Es ist die Untereinheit 3 der Cytochrom c-Oxidase, die zum respiratorischen Komplex IV gehört. Das Gen wid von den Nukleotiden 9207-9990 kodiert. Mutationen können verschiedene mitochondriale Erkrankungen auslösen. Dazu gehören Lebersche Optikusatrophie, Krampfleiden, Cytochrom c-Oxidasemangel, Laktatazidose und rekurrente Myoglobinurie. Alle mitochondrialen Gene werden im Zuge einer Diagnostik mitochondrialer Erkrankungen gemeinsam untersucht.
