A rare autosomal recessive primary immunodeficiency characterized by susceptibility to Epstein-Barr virus (EBV)-associated lymphoproliferative disorders such as malignant B-cell proliferation, Hodgkin lymphoma, B-cell lymphoma, lymphoid granulomatosis, hemophagocytic lymphohistiocytosis, and smooth muscle tumor. Patients present persistent symptoms of infectious mononucleosis including recurrent febrile episodes, lymphadenopathies, and hepatosplenomegaly, accompanied by high EBV viral load in the blood. Additional manifestations are autoimmune diseases like hemolytic anemia or renal disease.
