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:
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.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
