Wiskott-Aldrich Syndrome is a rare X-linked immunodeficiency disease characterized by immunodeficiency, thrombocytopenia, and eczema. It is caused by mutations in the WAS protein gene which regulates actin cytoskeleton organization. This leads to defects in T-cells and B-cells, recurrent infections, bleeding issues, and increased cancer risk. The only cure is hematopoietic stem cell transplant from a matched sibling donor, while treatment focuses on antibiotics, platelet transfusions, and IVIG for antibody replacement.
