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.
- ClinGen juge le lien définitif
- 6 évaluateurs GenCC le classent comme définitif ou fort
▶Actionnabilité
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.
