Infos zur Erkrankung
Auffälligkeiten des Corpus Callosum (ACC) sind häufige Fehlbildungen im Gehirn und gewöhnlich nach der 20. Schwangerschaftswoche zu diagnostizieren. Föten mit isolierten ACC haben eine bessere Prognose als solche mit zusätzlichen Anomalien. Allerdings machen die unvorhersehbaren neurologischen Entwicklungsergebnisse der isolierten ACC die pränatale Beratung zu einer besonderen Herausforderung. ACC sind heterogene Erkrankungen, die als Manifestation im Rahmen von >200 genetisch bedingten Syndromen auftreten können und insbesondere auch in Assoziation mit größeren Fehlbildungen des embryonalen Vorderhirns beobachtet werden. Zu den häufigsten postnatalen Befunden bei Patienten mit ACC gehören mentale Retardierung, Sehstörungen, Sprachverzögerung und Krampfanfälle. Selbst bei Fällen ohne Entwicklungsverzögerung und normaler Intelligenz sind leichte Verhaltens- oder soziale Probleme sowie ADHS beschrieben. Genetische Faktoren sind sehr häufig. Bei den genetischen Ursachen wird in 30-45% der Fälle eine "syndromale Diagnose" gestellt, und in 20-35% kann eine monogene Ursache ermittelt werden. Die zahlreichen genetischen Ursachen von ACC gehen mit autosomal-dominantem, autosomal-rezessivem und X-chromosomalem Erbgang einher. Ein negatives molekulargenetisches Ergebnis stellt keinen Ausschluss der klinischen Diagnose dar.
