Title: Effects Of Eltrombopag On Thrombocytopenia, Platelet Function and Bleeding In Patients With Wiskott-Aldrich Syndrome/X-Linked Thrombocytopenia.
Brief Summary: The purpose of this project is to describe the pathophysiology of thrombocytopenia and bleeding in patients with Wiskott-Aldrich Syndrome (WAS) and determine the response to thrombopoietic agents in vitro and in vivo.
