Cleidocranial dysplasia is a rare disease with an autosomal dominant inheritance pattern. Abnormalities caused by mutations in the short arm of chromosome 6 affect the skeletal system, mainly the scull, teeth, and clavicles. Symptom variability, from isolated anomalies to full disease manifestation, occurs even among members of the same family. The present work describes a case of disease manifestation in a mother and a newborn, both burdened with cleidocranial dysplasia.
