Description : The Antley-Bixler syndrome (ABS) is an exceptionally rare craniosynostosis syndrome
characterized by radiohumeral synostosis present from the perinatal period. There
is a wide spectrum of anomalies seen in ABS, including midface hypoplasia, choanal
stenosis or atresia, and multiple joint contractures. Mortality has been reported
to be as high as 80% in the neonatal period, primarily due to airway compromise, and
prognosis improves with increasing age (summary by McGlaughlin et al., 2010).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the fibroblast growth factor receptor 2 gene (FGFR2, 176943.0002);
