Gain- and loss-of-function mutations in phosphoinositide 3-kinase-δ (PI3Kδ) result in a primary immunodeficiency syndrome termed APDS. Understanding the function of PI3Kδ in adaptive immune responses — from studies of mouse models of these mutations and from patients with APDS — provides new insights on how mutations in PI3Kδ promote immunodeficiencies.
