Living with Craniosynostosis 2

A genetic form of early skull closure (Boston type) that changes head shape, sometimes with hand and foot differences.

Understanding Craniosynostosis 2

Craniosynostosis 2 (Boston type) is a form of syndromic craniosynostosis in which skull bones close early, with highly variable effects.

Features include a prominent forehead, a short and tall head, and sometimes a cloverleaf-shaped skull. Other findings can include cleft palate, extra teeth, and limb differences such as a three-boned thumb and joined fingers. Problems can include headache, poor vision, and seizures. Intelligence is normal. It starts in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists this as the most common:

  • Early closure of skull bones (craniosynostosis)
  • Prominent forehead
  • Headache
  • Poor vision
  • Seizures

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 and genetic specialists.

  3. Consider genetic testing

    Changes in MSX2 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.
