title: Absence of messenger RNA and gene DNA for beta-globin chains in hereditary persistence of fetal hemoglobin.
abstract: The relative amounts of alpha-amd beta-globin mRNA and globin gene DNA were measured in reticulocyte RNA and lymphocyte DNA of an individual with homozygous hereditary persistence of fetal hemoglobin whose red blood cells contain 100% fetal hemoglobin (hb F: alpha2gamma2.) Molecular hybridization assays used as probes full-length DNA copies of human alpha- and beta-globin messenger RNA. The results of these hybridization assays demonstrated the expected amounts of alpha-globin mRNA and gene DNA, but absence of beta-globin mRNA and absence of beta-globin gene DNA. In the individual studied, hereditary persistence of fetal hemoglobin is associated with total deletion of the beta-globin structural gene.
