Comments: Found in a 65-year-old female in a Tunisian study of δ-thalassaemia. Crystallographic structure analysis demonstrated that the Ala62Pro variant probably leads to a significant conformational change that affects the secondary structure of the delta subunit. In fact, the Ala62 is the 6th amino acid is involved in the formation of the 5th α-helix and its change to proline would destabilize the conserved structure of the 5th α-helix.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
