title: Linkage-disequilibrium of the senegal haplotype with the beta S gene in the republic of guinea.
abstract: We have determined the beta gene cluster haplotype in 40 chromosomes carrying the beta S mutation from individuals of the major ethnic groups living in the Republic of Guinea. Thirty-one of these were either the typical (n = 29) or the atypical (n = 2) Senegal haplotype demonstrating that in this region of Atlantic West Africa, the sickle mutation is in linkage disequilibrium with this particular beta-gene cluster haplotype. Two individuals carrying one chromosome bearing the Benin haplotype were of Malinke ethnic origin. This is in keeping with the hypothesis that the Senegal beta-gene cluster haplotype is linked to the beta S gene in Atlantic West Africa.
