Hypogonadisme hypogonadotrope
Fonctionnement ovarien ou testiculaire anormal dû à une stimulation hormonale insuffisante issue de l'axe hypothalamo-hypophysaire.
- 4 soumetteurs GenCC le classent comme définitif ou fort
Craniosténose syndromique
Maladies associant une fermeture précoce des sutures crâniennes à d'autres signes, notamment les syndromes d'Apert, de Crouzon, de Pfeiffer, de Muenke et de Saethre-Chotzen, causées par des gènes tels que FGFR2, FGFR3, FGFR1, TWIST1, TCF12 et ERF.

- 5 soumetteurs GenCC le classent comme définitif ou fort
Ce que la connaissance change
Un diagnostic précoce permet une chirurgie au bon moment et un suivi de la croissance du crâne, de la vision et de l'audition ; les formes plus légères, comme le syndrome de Muenke, peuvent passer inaperçues chez l'adulte, ce qui est important pour la planification familiale.
