Living with Craniotelencephalic dysplasia

An extremely rare syndrome with early skull closure, a bulge of brain tissue at the forehead, and severe brain differences.

Understanding Craniotelencephalic dysplasia

Craniotelencephalic dysplasia is an extremely rare genetic syndrome with early skull closure, a frontal encephalocele, and several brain differences.

A frontal encephalocele is a bulge of brain tissue through the forehead. Brain differences can include extra fluid, a missing corpus callosum, and smooth or abnormal brain folds. These cause marked brain dysfunction, seizures, and very severe delays in development. GARD notes there have been no further descriptions in the medical literature since 1983. It is present from birth.

Signs & symptoms

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

  • Early closure of skull bones (craniosynostosis)
  • Frontal encephalocele
  • Extra fluid in the brain (hydrocephalus)
  • Seizures
  • Global developmental delay
  • Vision problems

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, brain and nervous system specialists, genetic specialists and seizure and epilepsy specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

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