title: A syndrome of immunoglobulin A deficiency, diabetes mellitus, malabsorption, a common HLA haplotype. Immunologic and genetic studies of forty-three family members.
abstract: Three persons in a kindred of 43 had variable expression of a syndrome consisting of immunoglobulin A deficiency, diabetes mellitus, malabsorption, and a common HLA haplotype. Findings from the proband included life-threatening malabsorption; idiopathic intestinal mucosal atrophy with infalmmation; IgA deficiency and antibodies to multiple endocrine organs; insulin-dependent diabetes mellitus; and the major histocomptability antigens HLA-A2, B8, and DW3. In addition to the described syndrome other conditions present in the family include Graves' disease, vitiligo, hypocomplementemia, rheumatic fever, multiple sclerosis, and a high frequency of antibodies to endocrine tissue. Since Graves' disease, diabetes mellitus, and idiopathic Addison's disease have all been described in association with HLS-B8 and DW3, we believe that the occurrence of these diseases in this family suggests that a single immune response gene or gene complex is linked with HLA-B8 and DW3.
