Cleidocranial dysostosis or Cleidocranial dysplasia is a hereditary congenital abnormality of humans due to haploinsufficiency caused by mutations in the CBFA1 gene, on [1] the short arm of chromosome 6.


It has one or more of these features:

  • The collarbones are partly or completely missing. If they are completely missing, the shoulders can touch each other in front of the chest.
  • The fontanelles of the skull are late in closing, or never close.
  • Extra teeth
  • Permanent teeth not erupting.
  • Bossing (= bulging) of the forehead.
