title: The HLA A1-B8 haplotype extends 6 Mb beyond HLA-A: associations between HLA-A, B, F and 15 microsatellite markers.
abstract: Allele frequencies for HLA-A, B and F and 15 microsatellite markers located from 100 kb telomeric to HLA-A to 6 Mb telomeric have been determined in a group of 60 blood donors. Linkage disequilibrium analysis revealed significant haplotype associations even after correction for the number of comparisons made. The HLA-A1, B8 haplotype extends as far as D6S276 (6.0 Mb telomeric to HLA-A). It is important to realize that this common haplotype extends beyond the HLA region, especially when evaluating haplotype associations with particular disorders.
