The signs and symptoms of Wiskott-Aldrich syndrome (WAS) usually appear soon after birth or within the first year of life. Common signs and symptoms occur because of a low number of normal platelets. This may include easy bruising or bleeding, tiny red spots on the skin (petechiae), blood in bowel movements, bleeding gums, and nose bleeds.

Babies with WAS may also have a lot of infections because they have a low number of white blood cells. Common types of infections are ear and sinus infections, and lung infection (pneumonia). Another common sign of WAS is eczema, which is an itchy rash of the skin.
