The ß-globin gene of a patient with mRNA-deficient ß°-thalassemia has been sequenced. We find a single nucleotide deletion in amino acid codon 44 that produces a UGA terminator at codon 60. We have previously shown that the ß-globin mRNA of this patient is correctly spliced and polyadenylated, but rapidly turns over with a half-life of less than 30 min. We suggest that the rapid mRNA turnover is influenced by the deletion of this single nucleotide as well as by the nonsense codon.
