Living with Craniosynostosis and dental anomalies

A rare genetic condition with early skull closure, a flat middle face, and late or extra teeth.

Understanding Craniosynostosis and dental anomalies

Craniosynostosis and dental anomalies is a rare genetic condition in which many skull seams close early and the teeth develop differently.

The early closure changes the shape of the head. People also have a flat middle face, delayed or misplaced teeth, and extra teeth. Facial features include bulging eyes, wide-set eyes, a beaked nose, and a relatively large lower jaw. Joined or curved fingers or toes, short stature, delays in thinking or movement, and hearing loss from the middle ear have also been reported. It starts in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Early closure of skull bones (craniosynostosis)
  • Late-coming and extra teeth
  • Bad bite and dental crowding
  • Bulging eyes (proptosis)
  • Hearing loss from the middle ear
  • Chiari malformation

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, genetic specialists and gum, teeth and mouth specialists.

  3. Consider genetic testing

    Changes in IL11RA are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    World Craniofacial Foundation may keep lists of experts for this condition.

InheritanceAutosomal Recessive
GenesIL11RA

It is caused by changes in the IL11RA gene. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
