Craniosynostosis 1; Crs1

Description

Craniosynostosis is a primary abnormality of skull growth involving premature fusion of the cranial sutures such that the growth velocity of the skull often cannot match that of the developing brain. This produces skull deformity and, in some cases, raises intracranial pressure, which must be treated promptly to avoid permanent neurodevelopmental disability (summary by Fitzpatrick, 2013). Mutation in the TWIST1 has been found to cause coronal and sagittal forms of craniosynostosis. Genetic Heterogeneity of CraniosynostosisCraniosynostosis-2 (CRS2 ) is caused by mutation in the MSX2 gene (OMIM ) on chromosome 5q. Craniosynostosis-3 (CRS3 ) is caused by mutation in the TCF12 gene (OMIM ) on chromosome 15q21. Craniosynostosis-4 (CRS4 ) is caused by mutation in the ERF gene (OMIM ) on chromosome 19q13. Susceptibility to craniosynostosis-5 (CRS5 ) is conferred by variation in the ALX4 gene (OMIM ) on chromosome 7p21. Craniosynostosis-6 (CRS6 ) is caused by mutation in the ZIC1 gene (OMIM ) on chromosome 3q24. Susceptibility to craniosynostosis-7 (CRS7 ) is conferred by variation in the SMAD6 gene (OMIM ) on chromosome 15q22.
