Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia. Hypoplastic clavicles, delayed closure of the cranial sutures, dental abnormalities, and short stature are main features in this syndrome. RUNX2 is the responsible gene for CCD. Here we reported two cases with CCD; they are admitted to clinic for short stature and dental abnormalities. We report these cases to increase the awareness of clinicians.
