IthaID: 3226



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: IVS II-2 T>G HGVS Name: HBB:c.315+2T>G
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: Mutation in the splice donor site (GT at 5′ end of intron), forming a premature stop codon in positions IVS II:19-21, thus ending protein translation.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
