Living with Oculopharyngeal muscular dystrophy

A genetic muscle condition that usually begins after age 40 with droopy eyelids and trouble swallowing.

Understanding Oculopharyngeal muscular dystrophy

Oculopharyngeal muscular dystrophy is a genetic condition with muscle weakness that begins in adulthood, typically after age 40.

Weakness first shows as droopy eyelids (ptosis), then trouble swallowing, starting with dry food. Many people also have weakness of the tongue and of muscles in the shoulders, upper legs, and hips. The weakness slowly gets worse, and some people use a cane or walker. A rarer severe form can start before age 45 and also affect nerves and thinking.

Signs & symptoms

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

  • Droopy upper eyelids (ptosis)
  • Trouble swallowing (dysphagia)
  • Weakness in the shoulder, hip and upper leg muscles
  • Tongue weakness and wasting
  • Weak eye muscles (ophthalmoplegia)
  • Tiredness and 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, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in PABPN1 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.

Changes in the PABPN1 gene cause this condition. GARD lists both autosomal dominant inheritance, where one changed copy can be enough, and autosomal recessive inheritance, where a child inherits a changed copy from each parent.
