Living with Spondyloepiphyseal dysplasia

A group of genetic bone conditions that affect how the spine, arms, and legs grow.

Understanding Spondyloepiphyseal dysplasia

Spondyloepiphyseal dysplasia is a rare group of genetic bone conditions that affect how the spine, arms, and legs grow and develop.

There are two main forms. One is present at birth (congenita), and one develops later in childhood or the teen years (tarda). Signs can appear at any time in life. Some people also have vision and hearing problems, clubfeet, cleft palate, arthritis, or breathing problems as the spine curves more over time.

Signs & symptoms

GARD doesn't list specific symptoms in a separate list, but the summary describes:

  • Differences in how the spine and limbs grow
  • Vision and hearing problems
  • Feet that turn inward and up (clubfeet)
  • Cleft palate
  • Arthritis
  • Breathing problems as the spine curves

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

    Your doctor may refer you to a specialist who knows rare conditions.

  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.

Bring these questions to your next doctor visit
Which form do I or my child have, congenita or tarda?
How often should we have vision and hearing checks?
Would genetic testing tell us which gene is involved?

Quick facts

Symptoms usually startany time in life

Changes in genes that help make proteins for healthy bone and cartilage cause these conditions. A new genetic change may cause it, or a parent may pass it down.
