Craniofacial Abnormalities: Molecular Basis

Monogenic abnormalities of skull differentiation can be grouped into three categories: disorders of cranial ossification (craniosynostosis, foramina parietalia), of midface development (holoprosencephaly, cleft lip and palate) and of differentiation of the first and second branchial arches (branchio-oto-renal dysplasia and Treacher–Collins). Many of the genes identified in these groups code for transcription factors and signaling proteins.

Keywords: craniosynostosis; foramina parietalia; holoprosencephaly; cleft lip and palate; branchio-oto-renal dysplasia; Treacher–Collins
