Living with Autosomal dominant myoglobinuria

A rare inherited muscle condition with episodes of muscle pain and dark urine brought on by fever, infection, long exercise, or alcohol.

Understanding Autosomal dominant myoglobinuria

Autosomal dominant myoglobinuria is a rare inherited muscle condition with episodes of muscle pain and myoglobin (a muscle protein) in the urine.

Episodes can be brought on by fever, viral or bacterial infection, prolonged exercise, or alcohol. Occasionally they can lead to sudden kidney failure. Between episodes, people may have no symptoms, or mild muscle weakness and raised creatine kinase.

Signs & symptoms

GARD doesn't list a symptom list for this condition, but its summary describes these features:

  • Episodes of muscle pain (myalgia)
  • Myoglobin in the urine
  • Mild muscle weakness between episodes
  • Raised creatine kinase on blood tests

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.

Quick facts

InheritanceAutosomal Dominant

GARD says it is inherited in an autosomal dominant way, meaning one changed copy of the gene can be enough to cause it. Episodes can be brought on by fever, infection, long exercise, or alcohol.
