More roles have been ascribed for FGF signaling in craniofacial development, with FGFR1 specifically linked to skeletal dysplasias and craniosynostosis in both humans and mice, suggesting a mechanism by which Mir133b may regulate craniofacial development (Moosa and Wollnik, 2016). The gene discussed is MIR133B; the disease is skeletal dysplasia.
