Diseases

Show/Hide Table
Disease IDSourceNameDescription
604571 OMIMBare lymphocyte syndrome 1 (BLS1)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. The disease is caused by variants affecting the gene represented in this entry.
