IthaID: 3483

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 121 GAA>-AA HGVS Name: HBB:c.364delG
Hb Name: Hb Mahasarakham Protein Info: N/A

Also known as:

Comments: Single nucleotide deletion (-G) generating a frameshift, which results in an elongated β-globin and a modified C-terminal sequence. Found as a compound heterozygote with Hb E variant in a 2-year-old proband with transfusion-dependent beta-thalassaemia.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
