In this very rare form of craniosynostosis (fewer than 40 cases have been reported to date), children develop an asymmetrical, tower-shaped head, a short neck, webbing between fingers and toes, and extra fingers. It is the only type of craniosynostosis where a pattern of inheritance can be traced in families as a recessive gene. The molecular basis of the condition is unknown, whereas the genetic cause is known for Apert, Crouzon, Pfeiffer, and Saethre-Chotzen syndromes.
