Abstract

HLA-A, B, and C antigens and the HLA-linked markers BF, C2, and C4 were determined in 1,799 unrelated Caucasians, 140 North American blacks, 140 Chinese, and 66 Japanese. One allele of the C4A locus (Rodgers), C4A 6, was found to code for a functionally inactive product in HLA-B17 (Bw57)-positive individuals, but for a functionally active product in HLA-B37- or HLA-B27-positive individuals. Further studies revealed that the functionally inactive C4A 6 gene product was found only in one subtype of HLA-B17, namely, 17.1 (Bw57, long). In addition, it was found that the frequency of the other subtype of HLA-B17, namely, 17.2 (Bw58, short) varies greatly in different populations and that HLA-Bw58 is associated with either C4A 3,B 1 or C4A 3,B Q0.
