Living with Keutel syndrome

An inherited condition with hardened cartilage in the ears, nose, and airway, narrowed lung arteries, and short fingertips.

Understanding Keutel syndrome

Keutel syndrome is an inherited condition in which cartilage in the ears, nose, voice box, windpipe, and ribs hardens with calcium.

Other features include narrowing of the lung arteries (pulmonary artery stenosis), short fingers and nails that look like drumsticks, and facial differences. People may have hearing loss, repeated ear and sinus infections, frequent respiratory infections, mild intellectual disability, and a nasal voice. Most cases are diagnosed in childhood.

Signs & symptoms

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

  • Hardening of cartilage (calcification)
  • Narrowing of the lung artery
  • Hearing loss
  • Repeated ear and sinus infections
  • Short fingertips and nails
  • Mild intellectual disability

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 and genetic specialists.

  3. Consider genetic testing

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

  • 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 for the MGP gene confirm the diagnosis?
How often should the heart and lung arteries be checked?
Should hearing be tested regularly?
