ErkrankungHypophysenhormon-Defizienz, Differentialdiagnose

NGS +

[Sanger]

Der Hypophysenvorderlappen produziert und sezerniert spezifische Hormone wie Wachstumshormon (GH), Prolactin (PRL), Thyroidea-stimulierendes Hormon (TSH), Luteinisierendes Hormon (LH), Follikel-stimulierendes Hormon (FSH) und Adrenocorticotropische Hormon (ACTH). Insbesondere früh wirkende Faktoren, die sich an der Hypophysen-Organogenese beteiligen, sind nicht Hypophysen-spezifisch, sondern werden auch für die Entwicklung anderer Organe und Strukturen benötigt. Läsionen in diesen Genen können auch Defekte in der Entwicklung von kraniofazialen, sensorischen oder vielen anderen Strukturen verursachen. Stattdessen sind Faktoren, die später in der Spezifikation der hypophysären Zelllinien wirken, eher spezifisch für jeden Zelltyp, aber nicht unbedingt auf die sich entwickelnde oder reife Hypophyse beschränkt. Eine gestörte Expression oder Funktion dieser Faktoren verursacht Störungen in der Hypophyse und führt schließlich zur defizienten Sekretion von Hypophysen-Hormonen. Daher umfasst dieses panel viele Gene, deren Malfunktion zu einer sehr breiten klinischen Symptompalette führen kann. Es werden alle monogenen und auch multifaktorielle Erbgänge beobachtet. In 20–30% der familiären Fälle werden vollständig penetrante Mutationen in bekannten Genen identifiziert. Die DNA-diagnostische Ausbeute ist jedoch derzeit insgesamt nicht bekannt, sodass eine klinische Diagnose durch ein negatives molekulargenetisches Ergebnis keinesfalls ausgeschlossen werden kann.
