Living with Ullrich congenital muscular dystrophy

A genetic muscle condition with weakness from birth, stiff knees and elbows, and very loose wrists and ankles.

Understanding Ullrich congenital muscular dystrophy

Ullrich congenital muscular dystrophy is a genetic condition that mainly affects the muscles used for movement.

People have muscle weakness soon after birth, tight joints (contractures) in the knees and elbows, and unusually loose wrists and ankles. It is noticed in the newborn period or infancy.

Signs & symptoms

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

  • Muscle weakness from birth
  • Low muscle tone (hypotonia)
  • Tight joints (contractures) in the knees and elbows
  • Very loose wrists and fingers
  • Hip dislocation
  • Frequent falls

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 brain and nervous system 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

    Muscular Dystrophy Association may keep lists of experts for this condition.
