<unk>  is a rare genetic disorder of the immune system.<unk>  stands for “p110 delta activating mutation causing senescent T cells, lymphadenopathy, and immunodeficiency.” The immunodeficiency manifests as recurrent infections usually starting in childhood. These include bacterial infections of the respiratory system and chronic viremia due to Epstein-Barr virus (EBV) and/or cytomegalovirus (CMV). Individuals with<unk>  also have an increased risk of EBV-associated lymphoma. Investigators Carrie Lucas, Michael Lenardo, and Gulbu Uzel at the National Institute of Allergy and Infectious Diseases at the U.S. National Institutes of Health and Sergey Nejentsev at the University of Cambridge, UK simultaneously described a mutation causing this condition which they called Activated PI3K Delta Syndrome (APDS).
