Living with Jackson-Weiss syndrome

A genetic condition with foot differences and early joining of skull bones that shapes the head and face.

Understanding Jackson-Weiss syndrome

Jackson-Weiss syndrome is a genetic condition with foot differences and early fusion of certain skull bones (craniosynostosis).

The early fusion keeps the skull from growing normally. It can cause a misshapen skull, widely spaced eyes, and a bulging forehead. Foot differences are the most consistent feature, and hands are almost always normal. Some people have hearing loss. People usually have normal intelligence. It is seen in newborns.

Signs & symptoms

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

  • Short, wide big toes that bend outward
  • Fused toes (syndactyly)
  • Early fusion of skull bones (craniosynostosis)
  • Wide-set eyes
  • Bulging forehead
  • Hearing loss in some people

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. 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 may keep lists of experts for this condition.

Everyday life

Living with a rare condition is easier with support.

  • Connect with Craniosynostosis and Positional Plagiocephaly Support Inc and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Can genetic testing find the gene change in my child?
When should skull shape be checked, and is surgery something to discuss?
Should we have regular hearing checks?

Quick facts

Symptoms usually startNewborn
InheritanceAutosomal Dominant

GARD says changes in genes (also called variants) cause this condition. It is autosomal dominant, meaning one changed copy of the gene is enough.
