Living with Multiple epiphyseal dysplasia type 4

A rare inherited bone condition with joint pain, stiff joints, and foot and hand differences, starting in childhood.

Understanding Multiple epiphyseal dysplasia type 4

Multiple epiphyseal dysplasia type 4 is a rare inherited bone condition that causes joint pain and stiffness starting in late childhood.

People with this type have pain in the hips, knees, wrists, and fingers, and sometimes limited joint movement. Hands, feet, and knees may be shaped differently, and the spine may curve (scoliosis). Adult height is slightly shorter. Early arthritis of the hip can occur.

Signs & symptoms

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

  • Hip joint pain
  • Joint pain and stiffness
  • Limited joint movement
  • Club feet (talipes equinovarus)
  • Knock knees (genu valgum)
  • Short stature, usually moderate

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. Consider genetic testing

    Changes in SLC26A2 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

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