Increased frequency of HLA‐DPw3 in severe aplastic anemia (AA)

Abstract
Thirteen patients with severe aplastic anemia (AA) were HLA-DP typed using primed lymphocyte typing (PLT). The frequency of HLA-DPw3 was significantly increased to 69% in AA as compared to 22% in 160 controls (p < 0.001; corrected p < 0.01, RR = 8.0).
