Living with Wiskott-Aldrich syndrome

A condition, mostly in males, that affects the immune system, causes eczema, and makes blood clot poorly.

Understanding Wiskott-Aldrich syndrome

Wiskott-Aldrich syndrome is a condition with a weak immune system, eczema, and a reduced ability to form blood clots.

It mainly affects males. Platelets (cells that help blood clot) are fewer and smaller than usual, from birth. This can cause easy bruising, bloody diarrhea, long bleeding after nosebleeds, and purple spots on the skin. White blood cell changes raise the risk of infections, autoimmune disorders, and some immune-system cancers.

Signs & symptoms

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

  • Easy bruising
  • Low platelet count
  • Eczema
  • Repeated infections
  • Chronic diarrhea
  • Autoimmune problems such as hemolytic anemia

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 allergy and immune system specialists, blood and bone marrow specialists, cancer specialists and genetic specialists.

  3. Consider genetic testing

    Changes in WAS 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

    Immune Deficiency Foundation and Wiskott-Aldrich Foundation may keep lists of experts for this condition.

Wiskott-Aldrich syndrome is caused by changes in the WAS gene. GARD lists X-linked inheritance, which is why it mainly affects males.
