Mitochondriales ATP6-Gen
Das mitochondriale Gen mit der offiziellen Bezeichnung MT-ATP6 kodiert ein Enzym des Elektronentransportes auf der inneren Mitochondrienmembran. Es ist die Untereinheit 6 des respiratorischen Komplexes V. Das Gen wid von den Nukleotiden 8527-9207 kodiert. Mutationen in diesem Gen können verschiedene mitochondriale Erkrankungen auslösen. Dazu gehören das NARP-Syndrom, die Lebersche Optikusatrophie, mentale Retardierung, Ataxie, der mitochondriale Komplex V-Mangel, hypertrophe Kardiomyopathie, infantile striatale Nekrose, Krampfleiden und Laktatazidose. Auch ein Zusammenhang mit Parkinsonismus wird diskutiert. Alle mitochondrialen Gene werden im Zuge einer Diagnostik mitochondrialer Erkrankungen gemeinsam untersucht.
