Cleidocranial dysostosis was diagnosed a family study was started. There are ten affected members in five generations. The partial or total absence of clavicles, the late closure of cranial sutures and fontanelles, the diastasis of the pubic symphysis and the flared chest during the first days of life, are constant features. Four presented characteristic facies and three delayed onset of first teeth which required extractions. There is hearing loss in three of them.
