Klinischer Kommentar

Ataxie ist ein Kardinalsymptom bei zerebellären Erkrankungen, kann aber auch ein Begleit-Symptom von hereditären spastischen Paraplegien, hereditären Polyneuropathien, neurologischen Entwicklungsstörungen und mitochondrialen Erkrankungen sein. Rezessive Ataxien zeigen oft komplexe Phänotypen, sogar noch mehr als ihre dominanten Gegenstücke, und können verschiedene assoziierte Merkmale aufweisen, einschließlich Neuropathie, pyramidale und extrapyramidale Beteiligung, okulomotorische Anomalien, kognitive Beteiligung, Krampfanfälle, Retinopathie, Hypogonadismus und viele andere. Einige Störungen haben eine relativ überwiegende zerebelläre Beteiligung im Vergleich zu anderen neurologischen und nicht-neurologischen Systemen. Andere komplexe motorische oder multisystemische Störungen zeigen ausgeprägte Ataxie. Schließlich gibt es Störungen, die gelegentlich mit Ataxie auftreten, aber die Ataxie ist ein sekundäres Merkmal. Bestimmte Erkrankungen mit geringen oder sekundären ataktischen Komponenten wurden hier nicht berücksichtigt, sofern die Ataxie schon von Beginn an als nebensächliche Symptomatik imponiert. Außerdem sind ataktische Störungen allelisch zu anderen Bewegungsstörungen, insbesondere bei spinozerebellären Ataxien und hereditären spastischen Paraplegien. Das Alter beim Auftreten kann von der Geburt bis zum (späten) Erwachsenenalter variieren. Schließlich besteht eine große phänotypische Variabilität zwischen Patienten aus verschiedenen Familien und sogar aus einer einzigen Familie mit demselben mutierten Gen, abhängig von der Art der Mutation und ihrer Position im Gen. Weitere Faktoren, die das Alter bei Beginn und den klinischen Verlauf beeinflussen, sind wahrscheinlich das Vorhandensein von modifizierenden Genen und Umwelt-Expositionen. Die DNA-diagnostische Ausbeute ist nicht bekannt, daher schließen negative Ergebnisse eine klinische Diagnose keineswegs aus.
