FGFR1 and craniosynostosis: From this list, we identified another potential candidate, FGFR1. Mutations in the FGFR family are known to cause craniosynostosis in various human syndromes [42], largely through an aberrant balance between apoptosis and proliferation of suture cells, making FGFR1 a logical potential target for investigation of the mechanism causing craniosynostosis in our model.
