DNA typing of HLA-DR antigens in systemic lupus erythematosus

We studied DNA polymorphisms of HLA-DR and DQ alleles in 63 American black patients with systemic lupus erythematosus (SLE). We found no HLA-DR beta, DQ alpha, or DQ beta restriction fragment length polymorphism (RFLP) or RFLP-determined DR or DQ specificity associated with SLE in either the patients or in 57 control subjects. DRw52b was positively associated with renal involvement and negatively associated with anti-nuclear RNP antibodies. Antibodies to Ro (SS-A) and La (SS-B) were associated with DR3(DRw17), DQw2.3. Early-onset SLE (less than or equal to 20 years of age) was associated with DRw8, and the frequency of neuropsychiatric involvement correlated negatively with a 3.7-kb Taq I DQ alpha RFLP. This suggests a role for DR and DQ genes in the clinical and serologic expression of SLE in American blacks.
