IthaID: 2232

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: -α27.6 HGVS Name: NG_000006.1:g.9079_36718del27640
Hb Name: N/A Protein Info: N/A
Also known as:

We follow the HGVS sequence variant nomenclature and IUPAC standards.

Comments: The deletion spans 27.6 kb on the α-globin gene cluster and involves deletion of the HBA2 gene, causing deficient α-globin production. The 5' breakpoint was at 9,079 bp and the 3' breakpoint at 36,718 bp.
