immune dysregulation syndrome

Group of primary immunodeficiencies characterized by autoimmunity, autoinflammation, and atopy due to defective immune regulation.

Full Definition

Immune dysregulation syndromes comprise a heterogeneous group of primary immunodeficiencies characterized by loss of immune homeostasis, leading to autoimmunity, autoinflammation, allergic disease, and sometimes immunodeficiency. These disorders result from defects in regulatory mechanisms that normally maintain self-tolerance and prevent excessive immune responses. Examples include IPEX syndrome (due to FOXP3 mutations affecting regulatory T-cells), ALPS (affecting lymphocyte apoptosis), and DOCK8 deficiency. Patients typically present with multiple autoimmune manifestations, severe allergies, chronic inflammation, and may have increased infection susceptibility despite immune hyperactivation.

Usage

Usage note: Encompasses various conditions with defective immune regulation; treatment often requires immunosuppression.
