Most α-thalassemia (α-thal) mechanisms are deletions of one or both α-globin genes and less than 5.0-10.0% are point mutations. Hb Agrinio [α29(B10)Leu→Pro, CTG>CCG (α2)] is a hyperunstable α chain structural variant in which the thalassemic phenotype is determined by a post translational precipitation of the structurally anomalous chain in erythroid(More)
Unstable hemoglobin (Hb) variants account for 9.5% of structural hemoglobinopathies. The majority of these unstable variants are the result of gene point mutations resulting in the substitution of a single amino acid by another. The presence of two mutations in the same allele is infrequent: of the 781 variants of the β-globin cluster described, only 32 are(More)
In the 5' untranslated region (5'UTR), which is transcribed but not translated and is involved in posttranscriptional regulation of the gene promoting and stabilizing the mRNA translation, several mutations associated with mild β-thalassemia (β-thal) have been described. One of these, the +20 (C>T) mutation, is described in the HbVar database as a mutation(More)
Thalassemias are the most frequent monogenic disorders around the world and are a serious health problem in areas with a high incidence. Thalassemias are particularly frequent in Mediterranean countries, the Middle East, Africa, the Indian subcontinent, and in the Southeast Asia. Of these, α-thalassemia is inherited as an autosomal recessive disorder.(More)
