Two alpha-globin structural mutants were mapped to their encoding loci by
in vitro translation of hybrid-selected alpha 1- and alpha 2-globin mRNA.
The more highly expressed mutant, alpha Spanish Town (alpha 27Val), is
encoded at the alpha 2 locus and the less expressed mutant, alpha Fort de
France (alpha 45Arg), is encoded at the alpha 1 locus. These results
further define the distribution of alpha-globin structural mutations within
the alpha-globin gene cluster and substantiate the dominant role of the
alpha 2-globin locus in alpha- globin expression.
