We identified a novel mutation of β-thalassemia (β-thal) in a heterozygous carrier from Azerbaijan. Phenotypical data and molecular mechanisms of codon 2 (-T) (HBB: c.9delT) was relevant to β0-thal. Additionally, we here report two new mutations on the HBB gene, not observed previously, in the local population as well as a non causative promoter mutation -198 (A>G) (HBB: c.-248A>G).
