Antley-Bixler syndrome in sisters: a term newborn and a prenatally diagnosed fetus

Am J Med Genet. 1983 Jan;14(1):139-47. doi: 10.1002/ajmg.1320140119.


Sisters with the Antley-Bixler syndrome are reported herein. The first infant died at 14 days of respiratory failure and the following findings characteristic of the syndrome: craniosynostosis of coronal and lambdoid sutures, brachycephaly, frontal bossing, severe midface hypoplasia with proptosis and choanal stenosis/atresia, humero-radial synostosis, medial bowing of ulnae, long slender fingers with camptodactyly, narrow iliac wings, anterior bowing of femora, cardiac and renal malformations. Unlike two previously published cases, she did not have connatal fractures, but she had vaginal atresia. Ultrasound examination in a subsequent pregnancy showed immobility at the elbows of the fetus, humero-radial synostosis, medial bowing of ulnae, and long hands and fingers. The fetus also had mild bowing of femora. The pregnancy was terminated in the 21st week and the findings were confirmed by clinical and radiologic examinations. Additional autopsy findings included cardiac and renal malformations. The Antley-Bixler syndrome is a recognizable malformation syndrome with a probable autosomal recessive mode of inheritance, which can be diagnosed in the fetus by midtrimester ultrasound examination.
