Abstract
In a detailed study of inheritance of DNA sequence polymorphism in a large reference pedigree, an individual was identified with an apparent genetic recombination event within the human beta-globin gene cluster. Analysis of the haplotypes of relevant individuals within this pedigree suggested that the meiotic crossing-over event is likely to have occurred within a 19.8-kilobase-pair region of the beta-globin gene cluster. Analysis of other DNA markers closely linked to the beta-globin gene cluster--segment 12 of chromosome 11 (D11S12) and loci for insulin, the cellular oncogene c-Ha-ras, and preproparathyroid hormone--confirmed that a crossover event must have occurred within the region of chromosome 11 between D11S12 and the beta-globin gene cluster. It is suggested that the event observed has occurred within a DNA region compatible with recombinational "hot spots" suggested by population studies.Entities:
