Craneosinostosis sindrómica
Enfermedades que combinan el cierre prematuro de las suturas craneales con otras características, entre ellas los síndromes de Apert, Crouzon, Pfeiffer, Muenke y Saethre-Chotzen, causadas por genes como FGFR2, FGFR3, FGFR1, TWIST1, TCF12 y ERF.
- ClinGen califica la relación como definitiva
- 6 remitentes de GenCC la califican como definitiva o fuerte
Qué cambia al conocerlo
El diagnóstico precoz permite realizar la cirugía a tiempo y hacer un seguimiento del crecimiento craneal, la visión y la audición; las formas más leves, como el síndrome de Muenke, pueden pasar desapercibidas en adultos, lo que es relevante para la planificación familiar.
