Living with Welander distal myopathy

A rare inherited muscle condition that starts in adulthood with weakness in the hands, later spreading to the feet.

Understanding Welander distal myopathy

Welander distal myopathy is a rare muscle condition that causes weakness in the hands and feet.

Weakness starts in the muscles that straighten the fingers and wrists. It later spreads to all hand muscles and then the muscles that lift the toes and ankles. It usually begins in adulthood.

Signs & symptoms

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

  • Weakness in the fingers and wrists
  • Wasting of hand muscles
  • Foot drop
  • High-stepping walk
  • Clumsiness
  • Changes in how a person walks

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 TIA1 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.
