Welcome to the WAS Foundation. This Foundation was created in honor of Sebastian Moustirats, a 20 month baby who lost his battle with WAS. Our mission is to help families, caregivers and patients diagnosed with WAS and other Immunodeficient disorders.

What is WAS? The classic form of WAS is characterized by an increased tendency to bleed caused by a reduced number of platelets, recurrent bacterial, viral and fungal infections and eczema of the skin.
