Coronal craniosynostosis and radial ray hypoplasia: a third report of Twist mutation in a 33 weeks fetus with diaphragmatic hernia.

We describe a multiple malformation syndrome comprising coronal craniosynostosis, unilateral radial ray hypoplasia and diaphragmatic hernia in a 33w female fetus born to a 46 y-old male with an alleged personal and family history of Crouzon syndrome. By identifying an already described c.445C>T TWIST missense mutation, we were able to reassign the diagnosis of the family condition to Saethre-Chötzen syndrome.
