  • Title: Hb Florida: a novel elongated C-terminal beta-globin variant causing dominant beta-thalassemia phenotype.
    Author: Weinstein BI, Erramouspe B, Albuquerque DM, Oliveira DM, Kimura EM, Costa FF, Sonati MF.
    Journal: Am J Hematol; 2006 May; 81(5):358-60. PubMed ID: 16628732.
    Abstract:
    We report here a new frameshift mutation in exon 3 of the beta-globin gene, a single nucleotide deletion (-C) in between codons 140/141 (GCC/CTG-->GCC/TG), found in an 8-year-old Argentinean girl with clinical picture of thalassemia intermedia. It leads to a beta-chain that is elongated to 156 amino acids [(141)Trp-Pro-Thr-Ser-Ile-Thr-Lys-Leu-Ala-Phe-Leu-Leu-Ser-Asn-Phe-(156)Tyr-COOH]. The resulting hemoglobin, which we named Hb Florida, was not detected in peripheral blood; however, erythroid hyperplasia and dyserythropoiesis with large inclusion bodies on methyl violet staining were observed in bone marrow, suggesting that this is a hyperunstable variant producing a dominant beta-thalassemia phenotype, since the other beta-allele was completely normal.
