An array of monogenic immune defects marked by autoimmunity, lymphoproliferation, and hyperinflammation rather than infections have been described. Primary immune regulatory disorders pose a challenge to pediatric hematologists and oncologists. This paper focuses on primary immune regulatory disorders including autoimmune lymphoproliferative syndrome (ALPS) and ALPS‐like syndromes, immunodysregulation, polyendocrinopathy, enteropathy, X‐linked (IPEX) and IPEX‐like disorders, common variable immunodeficiency (CVID), CVID‐like, and late‐onset combined immunodeficiency (CID) disorders. Hyperinflammatory disorders and those associated with increased susceptibility to lymphoid malignancies are also discussed. Using a case‐based approach, a review of clinical pearls germane to the clinical and laboratory evaluation as well as the treatment of these disorders is provided. |
