IthaID: 3281



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 130 (+T) HGVS Name: HBA1:c.393_394insT
Hb Name: Hb Sichuan Protein Info: N/A

Comments: The insertion of a thymidine (T) between codons 130 and 131 disrupts the normal reading frame after codon 131 inducing an in-phase stop codon 133 residues downstream, resulting in an extended α-globin chain with an extra 34 amino acids. It is responsible for a severe anaemia phenotype when combined with an α0-thal mutation.
