We report a case of the Antley-Bixler syndrome in an 11-year-old girl. She presented with bilateral proximal femoral focal deficiency, right clubfoot, left radiohumeral synostosis, bilateral ear hypoplasia, cleft palate, tongue tie, missing teeth, congenital heart disease, a pelvic kidney with hydronephrosis, and mental retardation. Proximal femoral focal deficiency has never been reported before as a manifestation of Antley-Bixler syndrome. Her mother was exposed to radiation during an intravenous urogram done in the first trimester of pregnancy. Exposure to radiation has not been implicated as a cause of Antley-Bixler syndrome.
