Antigen Society #10 Report (Bw57 and Bw58)

Data obtained in the Seventh International Histocompatibility Workshop suggested the existence of two alleles subtypic to HLA-B17(1,6). The subdivision of HLA-B17 was confirmed during The Eighth and Ninth International Histocompatibility Workshops, and the two subtypic were designated HLA-Bw57 and HLA-Bw58 (2–5). These two alleles are both included in HLA-Bw4 (1–6).
