Living with Childhood-onset progressive contractures-limb-girdle weakness-muscle dystrophy syndrome

A rare genetic muscular dystrophy beginning in childhood, with muscle weakness around the hips and shoulders and stiff, tight joints.

Understanding Childhood-onset progressive contractures-limb-girdle weakness-muscle dystrophy syndrome

Childhood-onset progressive contractures-limb-girdle weakness-muscle dystrophy syndrome is a progressive muscular dystrophy with weakness and tight joints.

Weakness starts in the legs and moves on to the arms and the muscles of the trunk. Over time, people can lose the ability to walk. Joints in the limbs, and sometimes the spine, become tight (contractures). Breathing may be affected to different degrees. The heart muscle is not involved.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but the summary describes these features:

  • Weakness around the hips and shoulders
  • Weakness that starts in the legs, then reaches the arms
  • Tight joints (contractures) in the limbs
  • Tight joints in the spine, sometimes
  • Breathing problems, in some

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. Consider genetic testing

    Changes in TTN 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

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