title: Hemoglobin Miyada: DNA analysis of the anti-Lepore beta delta fusion gene.
abstract: Hemoglobin Miyada, an anti-Lepore hemoglobin, represents the protein product of a nonhomologous crossover between beta and delta genes. The mutant globin is beta-like from the N terminus to amino acid 12, and delta-like from amino acid 22 through the C terminus, thus predicting a crossover site in the first coding region of the gene. DNA analysis, using multiple restriction endonucleases and hybridization to delta and beta globin gene-specific probes, confirms that the beta delta hybrid gene 1) is located on a single chromosomal fragment between normal delta and beta genes, and 2) has 5' beta promoter sequences, delta IVS 1 and 2, and 3' coding and flanking sequences.
