Primary Immune Deficiency Diseases (PIDDs)

There are more than 200 different forms of primary immune deficiency diseases (PIDDs) affecting only about 500,000 people in the United States. These rare genetic diseases may be chronic, debilitating, and costly. Since the 1970s, NIAID-supported investigators have been examining the causes and complications of PIDDs to improve the lives of patients and families. NIAID aims to improve diagnosis, explore new treatments and preventions for PIDDs, and facilitate genetic counseling. It is home to the Primary Immune Deficiency Clinic, which provides diagnoses and disease management recommendations to patients and families whose lives are touched by PIDDs.
