Abstract

We describe a family that segregated an autosomal dominant form of craniosynostosis characterized by variable expression and limited extra-cranial features. Linkage analysis and genome sequencing were performed to identify the underlying genetic mutation. A c.443C>T missense mutation in MSX2, which predicts p.Pro148Leu was identified and segregated with the disease in all affected family members. One other family with autosomal dominant craniosynostosis (Boston type) has been reported to have a missense mutation in MSX2. These data confirm that missense mutations altering the proline at codon 148 of MSX2 cause dominantly inherited craniosynostosis. © 2013 Wiley Periodicals, Inc.
