Wiskott-Aldrich syndrome is a PI disease that affects both the T and B lymphocytes. In addition, the plateletsâblood cells that help control bleedingâare reduced in number and size. People with WAS experience frequent bacterial, viral, and fungal infections; eczema of the skin; and an increased tendency to bleed. WAS is caused by mutationsâor mistakesâin the gene that produces a protein named for the disorder, the Wiskott-Aldrich Syndrome Protein (WASP), which is located on the X chromosome. Because the gene defect is carried on the X chromosome (X-linked recessive), only boys can inherit WAS.
