Recombinations defining centromeric and telomeric borders for the hereditary haemochromatosis locus.
Hereditary haemochromatosis (HFE) is a common inherited disorder, affecting approximately five per thousand white people of northern European descent. Genetic linkage and linkage disequilibrium studies indicate that the disease locus is tightly linked to HLA-A and D6S105. Recombination between HFE and HLA class I loci is known to be rare. We report here two pedigrees in which recombinations telomeric of HLA-A occurred. These recombinant events define new centromeric and telomeric borders for the HFE locus.
