Living with Ehlers-Danlos syndrome, familial joint laxity type

A rare inherited condition with very loose joints that dislocate often, with no skin changes.

Understanding Ehlers-Danlos syndrome, familial joint laxity type

Ehlers-Danlos syndrome, familial joint laxity type, is a rare inherited condition with generalized loose joints that dislocate repeatedly.

The joints most often affected are the hip, shoulder, elbow, and kneecap. Hip dislocation is often present from birth. People often have muscle and joint pain and may develop joint wear at a relatively young age. GARD says skin abnormalities are absent. It can begin at a variety of ages.

Signs & symptoms

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

  • Very flexible joints
  • Repeated joint dislocations
  • Hip dislocation present at birth
  • Kneecap dislocation
  • Muscle and joint pain
  • Early joint wear

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

    Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
