Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | -α6.9 | HGVS Name: | NG_000006.1:g.29785_36746del |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as:
Comments: The deletion spans approximately 6.9 kb on the alpha-globin gene cluster, removing the α2 gene but leaving the α1 gene intact. The 5' deletion breakpoint lies in the HBAP1 gene. Deletion breakpoints were determined by MLPA and Gap-PCR analyses. Reported in a compound heterozygous state with --SEA deletion in a proband presenting with HbH disease.
We follow the HGVS sequence variant nomenclature and IUPAC standards.

Note:
The impact thresholds provided in this section are based on the analyses performed in Tamana et.al. For any given tool, the impact thresholds defined for the set of variants with the same effect on function as the variant examined, are preferred over those defined for the full dataset.
