Mondo Description Immunodeficiency by defective expression of HLA class 1 is a very rare, primary, genetic, immunodeficiency disorder characterized by partial or complete absence of human leukocyte antigen class I expression resulting in a non-specific clinical picture of impaired immune response and susceptibility to infections.
Uniprot Description A HLA class I deficiency. Contrary to bare lymphocyte syndromes type 2 and type 3, which are characterized by early-onset severe combined immunodeficiency, class I antigen deficiencies are not accompanied by particular pathologic manifestations during the first years of life. Systemic infections have not been described. Chronic bacterial infections, often beginning in the first decade of life, are restricted to the respiratory tract.
Disease Ontology Description A severe combined immunodeficiency that is characterized by recurrent bacterial, viral, and fungal infections, especially of the lung, and sterile necrotizing granulomas of the skin, develops_from deficiency or decreased surface expression of MHC Class I, has_material_basis_in autosomal recessive inheritance of mutation affecting MHC Class I production or expression and frequently involves TAP1 and TAP2 subunits, and is typically asymptomatic in infancy.
