Wiskott-Aldrich Syndrome (WAS)
Wiskott–Aldrich syndrome is an extremely rare condition typified by the presence of eczema, thrombocytopenia (low number of platelets in the blood) and immune deficiency (causing severe, recurring infections).
It is more prevalent in males and occurs in roughly one in a million births.
Platelet loss can cause easy bruising and prolonged bleeding. Allogeneic hematopoietic stem cell transplants have been successful in reducing the mortality of this disorder.
