IthaID: 2023

Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 117 TTC>TCC [Phe>Ser] HGVS Name: HBA2:c.353T>C
Hb Name: Hb Foggia Protein Info: α2 117(GH5) Phe>Ser

Comments: Most likely the amino acid substitution impairs the interaction of the alpha-chain variant with the AHSP and prevents its stabilizing effect, thus leading to the alpha-chain pool reduction.
