Infos zur Erkrankung
Primäre Mikrozephalie (MCPH) ist eine Störung der Gehirnentwicklung, die dazu führt, dass der okzipitofrontale Kopfumfang signifikant unter dem Mittelwert für (Schwangerschafts-) Alter und Geschlecht liegt. MCPH hat viele nicht-genetische Ursachen, während die genetisch-bedingten Mikrozephalien/Syndrome insgesamt relativ selten sind. Bei Mikrozephalie mutierte Gene kodieren für zentrosomale Proteine (Zentriolen-Biogenese) und viele verschiedene mechanistische Kategorien, insbesondere DNA-Replikation und -Reparatur. Der Schweregrad der Entwicklungsverzögerung/ intellektuellen Behinderung scheint mit dem Schweregrad der primären Mikrozephalie zu korrelieren. Dieses Mikrozephalie panel ist gemäß den Leitlinien (s.u.) zusammengestellt bzw. fasst die relevanten Gene mehrerer Kategorien zusammen. Alle klassischen Erbgänge werden bei Mikrozephalie beobachtet, multifaktorielle Geschehen stehen jedoch ganz im Vordergrund. Die Diagnoseraten schwanken zwischen den Mikrozephalie-Kategorien und sind vordringlich von den klinischen Voruntersuchungsergebnissen abhängig. Ein unauffälliger genetischer Befund bedeutet keinen Ausschluss der klinischen Verdachtsdiagnose.
