Furthermore, recent reviews on FGFR2-related craniosynostosis syndromes have identified additional skeletal anomalies such as syndactyly, carpal and tarsal fusion, as well as synostosis of the radius and humerus among patients with Apert syndrome (OMIM 101200), Jackson-Weiss syndrome (OMIM 123150), and Pfeiffer syndrome (OMIM 101600), respectively [31]. This evidence concerns the gene FGFR2 and Apert syndrome.
