3. Genetic counseling

Craniosynostosis is caused by the premature fusion of one or multiple cranial sutures, often leading to abnormal head shape and facial features. In some cases craniosynostosis can result in increased intracranial pressure causing visual impairment, eating difficulties, and neurodevelopmental disability.

Craniosynostosis can occur in an isolated setting (nonsyndromic) or as part of a genetic syndrome (e.g. Crouzon, Pfeiffer, Apert, Muenke, and Saethre-Chotzen syndromes). Approximately 85 % of all cases of craniosynostosis are nonsyndromic.

The prevalence of craniosynostosis is estimated to affect 1 in 2,000 to 2,500 live births worldwide.
