title: Antley-Bixler syndrome with radioulnar synostosis.
abstract: This report describes a newborn boy with Antley-Bixler (AB) syndrome. AB syndrome is a rare disorder characterized mainly by craniosynostosis and multiple joint contractures including radiohumeral synostosis. Our patient differs from the usual presentation by the presence of radioulnar rather than a radiohumeral synostosis. In addition, the child had a FGFR1 1300T mutation, which has not previously been associated with AB syndrome. Thus, our patient presents unique features and represents another argument in favour of an AB-like spectrum rather than a single syndrome.
