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.
