title: Association of HLA-DQw4 with IgA nephropathy in the Japanese population.
abstract: We have studied HLA-A, B, DR and DQ phenotypes in 50 Japanese patients with IgA nephropathy. The antigen frequency of HLA-DQw4, which is known to be associated with DR4/Dw15 specificity, was increased in the patient group as well as in those of B35 and DR4. The increase of DQw4 (36.0%) was significantly different from that of national controls (corrected p less than 0.004).
