IthaID: 3281
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | CD 130 (+T) | HGVS Name: | HBA1:c.393_394insT |
| Hb Name: | Hb Sichuan | Protein Info: | N/A |
| Also known as: |
We follow the
HGVS sequence variant nomenclature
and
IUPAC standards.
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.
