IthaID: 3391

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: IVS II-648/649 (-T) HGVS Name: HBB:c.316-202del
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: Found as a heterozygote in a proband with haematological parameters suggestive of a β-thalassaemia carrier. In silico analysis suggests that the T deletion could create a consensus active 5' donor splice site (GT).

We follow the HGVS sequence variant nomenclature and IUPAC standards.
