Craniosynostosis
Sagittal craniosynostosis
Sagittal craniosynostosis is the most common type and causes a narrow and long skull (dolichocephaly). Most cases are isolated and sporadic, with recurrence risk of transmission to future offspring < 3%. Learning disability may be present in up to 40 to 50% of patients. Several genes have been implicated in sagittal craniosynostosis, but chromosomal microarray analysis is not typically necessary unless developmental delays or other congenital anomalies are present.
