Living with Facioscapulohumeral muscular dystrophy

A genetic muscle condition that causes slowly worsening weakness, first in the face, shoulders, and upper arms.

Understanding Facioscapulohumeral muscular dystrophy

Facioscapulohumeral muscular dystrophy is a genetic disorder that causes weakness and wasting of muscles, mainly in the face, shoulders, and upper arms.

Symptoms usually start in the teen years, but can begin later or, rarely, in infancy. Facial weakness can make it hard to whistle or smile. Weak shoulder muscles can make the shoulder blades stick out. Weakness slowly worsens over decades and may spread to the legs and hips.

Signs & symptoms

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

  • Weakness of face muscles
  • Eyelids that do not close fully at night
  • Shoulder and upper arm weakness
  • Foot drop with frequent falls
  • Weak belly and hip muscles
  • Chronic pain

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 SMCHD1 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

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