Wiskott-Aldrich syndrome (WAS): A diagnosis-specific episode

April 30, 2021

The IDF Podcast · Wiskott-Aldrich Syndrome (WAS) - A Diagnosis-Specific Episode

Wiskott-Aldrich syndrome or WAS is a unique form of primary immunodeficiency. WAS primarily affects males because it’s an X-linked recessive condition and is characterized by abnormal bleeding and eczema of the skin. To discuss WAS further, we will be talking with our guest, Sumathi Iyengar, the Executive Director of the Wiskott-Aldrich Foundation. Dr. Iyengar is a pediatrician-turned-advocate for WAS after her son was diagnosed at a young age. She is a partner and longtime friend of IDF.
