Klinischer Kommentar

Mitochondriale Myopathien sind eine Gruppe von fortschreitenden Muskelerkrankungen, die in erster Linie durch die Beeinträchtigung der oxidativen Phosphorylierung verursacht werden. Die Myopathie ist aufgrund des hohen zellulären Energiebedarfs der Skelettmuskulatur eine der häufigsten Manifestationen von mitochondrialen Erkrankungen im Erwachsenenalter. Allerdings zeigen Patienten mit mitochondrialer Myopathie oft auch eine Dysfunktion in mehreren Organsystemen, was zur großen Variabilität im klinischen Phänotyp und der Prognose führt. Diese Erkrankungen sind daher praktisch immer multisystemische Störungen, die sich unter anderem mit einer Vielzahl von neurologischen, hepatischen und gastrointestinalen Symptomen präsentieren. Die Myopathie führt oft zu Belastungsintoleranz, Krämpfen und Müdigkeit. Proximale Myopathie ist die häufigste Form, der Grad der Schwäche ist variabel, die Patienten häufig schnell ermüdbar. Bei einigen Patienten ist auch die Atemmuskulatur betroffen, so dass apparative Beatmung erforderlich wird. Chronisch progressive externe Ophthalmoplegie ist eine häufige Erscheinung bei Patienten mit mitochondrialer Erkrankung und ist häufig mit proximaler Myopathie verbunden. Darüber hinaus sind belastungsinduzierte Muskelschmerzen ein häufiges Merkmal, selten Rhabdomyolyse, während Müdigkeit das am häufigsten von den Patienten berichtete Symptom ist. Die Erkrankungen aus dieser Gruppe werden anhand praktisch unübersehbar vieler Kerngenom-Mutationen zumeist autosomal rezessiv, seltener autosomal dominant und nur ausnahmsweise X-chromosomal vererbt. Die molekulargenetische Ausbeute ist bei mitochondrialen Leiden nur sehr schwer und mit erheblichen Einschränkungen zu erfassen. Ein negatives molekulargenetisches Ergebnis stellt keinen Ausschluss der klinischen Diagnose dar.
