Living with Myhre syndrome

A rare condition affecting connective tissue, with short height, stiff joints, hearing loss, and scarring in skin and organs.

Understanding Myhre syndrome

Myhre syndrome is a rare condition that affects connective tissue, which gives strength and flexibility to structures throughout the body.

It affects many parts of the body, though not everyone has every feature. Common features include short height, bone differences, limited joint movement, distinct facial features, intellectual and behavioral differences, and hearing loss. Scar tissue (fibrosis) can build up in the skin and organs, and there can be heart and lung differences. Growth is reduced, starting before birth. Some features become more noticeable with age.

Signs & symptoms

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

  • Short stature
  • Joint stiffness
  • Hearing loss
  • Intellectual disability
  • Delayed development
  • High blood pressure

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 SMAD4 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

    Myhre Syndrome Foundation and Little People of America may keep lists of experts for this condition.
