Living with Auriculoosteodysplasia

A very rare genetic condition with distinctive ear shape, bone differences, and slightly short height.

Understanding Auriculoosteodysplasia

Auriculoosteodysplasia is a very rare genetic condition that causes multiple bone differences, a distinctive ear shape, and slightly short stature.

The earlobe is long and attached, with a small lobule slightly toward the back. Other features can include collarbone and forearm bone differences, elbow dislocation, and hip dysplasia. It is noticed in newborns.

Signs & symptoms

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

  • Distinctive ear shape with an attached earlobe
  • Short stature
  • Collarbone differences
  • Small or missing forearm bone (radius)
  • Elbow dislocation
  • Hip dysplasia

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.
