title: The Bf locus in the HLA region of chromosome 6: linkage and association studies.
abstract: Bf allele frequencies in a material of 172 unrelated Norwegians are given. Bf/HLA linkage relations in 49 informative matings with 178 children, and Bf/HLA association data of a material of 212 Bf-HLA haplotypes are presented. Of 171 informative meioses, there were no Bf-HLA-B recombinations, while 3 out of 158 Bf-HLA-A informative meioses showed recombination. There is significant association between the BfF and the HLA-BW35 allele. It is concluded that the Bf locus is situated on the HLA-B side of HLA-A within the HLA region, in very close proximity to HLA-B.
