A rare genetic primary immunodeficiency due to a defect in adaptive immunity characterized by severe immunodeficiency, presenting with profound susceptibility to viral, fungal and bacterial infections due to impaired CD25-mediated T-regulatory cell function, in association with severe autoimmune disease, such as alopecia universalis, erythrodermia, and autoimmune thyroiditis and enteropathy.
