Living with Quebec platelet disorder

A rare inherited bleeding disorder that causes bleeding after injury or surgery, bruising, and joint and muscle bleeds.

Understanding Quebec platelet disorder

Quebec platelet disorder is a rare inherited bleeding disorder caused by a problem with the small storage packets (granules) inside platelets.

People can have moderate to severe bleeding after injury, surgery, or childbirth. They also have frequent bruising, bleeding from the nose and mouth, and bleeding into muscles and joints. GARD lists onset in adulthood.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. The summary describes these features:

  • Bleeding after injury, surgery, or childbirth
  • Frequent bruising
  • Bleeding from the nose or mouth (mucocutaneous)
  • Bleeding into muscles

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.
