IthaID: 3286

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 61 AAG>TAG [Lys>STOP] HGVS Name: HBA2:c.184A>T
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The mutation causes a premature termination of translation, likely leading to nonsense-mediated degradation mRNA or a truncated and unstable protein product.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
