Phenotypic association and highly significant linkage disequilibria have been demonstrated for HLA-B18 and BfF1 and HLA-Bw50 and BfS1 alleles among Caucasians from Australia and the United States (San Francisco Bay area). The HLA-B18, BfF1 association appears to be associated with HLA-Aw30. It is possible that BfS1 arose as a mutation, after the evolutionary splitting of HLA-Bw21, on an HLA-Bw50 haplotype, and that BfF1 arose on an HLA-Aw30, B18 haplotype.
在来自澳大利亚和美国（旧金山湾区）的白种人中，已证实HLA - B18与BfF1以及HLA - Bw50与BfS1等位基因之间存在表型关联和高度显著的连锁不平衡。HLA - B18与BfF1的关联似乎与HLA - Aw30有关。有可能BfS1是在HLA - Bw21进化分裂后，在一个HLA - Bw50单倍型上作为突变产生的，而BfF1是在一个HLA - Aw30、B18单倍型上产生的。
