Immunodeficiency-36 with lymphoproliferation (IMD36) is an autosomal dominant primary immunodeficiency with a highly heterogeneous clinical phenotype, characterized primarily by recurrent respiratory tract infections, lymphoproliferation, and antibody deficiency. Other features include growth retardation, mild neurodevelopmental delay, and autoimmunity. The major complication is development of B-cell lymphoma (Elkaim et al., 2016).

Immunodeficiency-102 (IMD102) is an X-linked recessive immunologic disorder characterized by the onset of recurrent sinopulmonary, mucosal, and other infections in early childhood, usually accompanied by refractory autoimmune cytopenias. Affected individuals have bacterial, viral, and fungal infections, as well as hemolytic anemia, thrombocytopenia, lymphopenia, and decreased NK cells. Laboratory studies show defective T-cell proliferation and function, likely due to signaling abnormalities. The disorder may also manifest as a hyperinflammatory state with immune dysregulation (Delmonte et al., 2021).

Immunodeficiency-117 (IMD117) is an autosomal recessive immunologic disorder characterized by increased susceptibility to disseminated mycobacterial infection apparent in early childhood. Affected individuals develop mycobacterial disease after BCG (bacille Calmette-Guerin) vaccination and show increased susceptibility to other mycobacterial infections, such as M. avium. Immunologic workup shows impaired development of myeloid and lymphoid cell subsets that secrete and respond to gamma-interferon (IFNG; 147570) (et al., 2023).
