Living with Omodysplasia

A rare bone condition causing short limbs and distinct facial features, in a more severe and a milder form.

Understanding Omodysplasia

Omodysplasia is a rare skeletal condition with shortened limbs and distinct facial features.

There are two types. The recessive (generalized) form causes severe shortening of both upper and lower limbs. The dominant form causes shortening limited to the upper limbs, with normal height. GARD lists newborn and infant years as the usual onset.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on its summary, features may include:

  • Shortened arms and legs
  • Distinct facial features
  • Short stature (in the recessive form)
  • Dislocated radius, a forearm bone (in the recessive form)

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

    Little People of America may keep lists of experts for this condition.
