Living with Cooper-Jabs syndrome

A rare genetic syndrome with missing ear canals and hearing loss, intellectual disability, and heart and skeletal differences.

Understanding Cooper-Jabs syndrome

Cooper-Jabs syndrome is a rare genetic syndrome with a missing ear canal and hearing loss, plus differences in the face, bones, and heart.

People have a missing outer ear canal (atresia), which causes moderate hearing loss. They also have intellectual disability, a hole in the heart wall, and a belly button hernia. There can be skeletal differences, such as mild clubfoot and long fifth fingers, and facial features such as a prominent forehead and flat back of the head. It starts at birth.

Signs & symptoms

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

  • Missing ear canal (atresia)
  • Hearing loss (conductive)
  • Intellectual disability
  • Hole between the lower heart chambers
  • Low muscle tone (hypotonia)
  • Crossed eyes (strabismus)

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 brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

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

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • 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

Quick facts

Symptoms usually startNewborn
InheritanceAutosomal Recessive

GARD says changes in genes cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent. GARD doesn't name a gene.
