IthaID: 2156
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | Algerian HPFH deletion | HGVS Name: | NG_000007.3:g.57141_81002del; 81008delA |
| Hb Name: | N/A | Protein Info: | deletion of 23860 nts from the δ gene to β gene |
Also known as:
Comments: Found in combination with Hb C in a female presenting with a chronic normochromic and normocytic anaemia. Haemoglobin analysis revealed the presence of HbC (57%), HbF (41%) and an absence of HbA. The deletion spans approximately 23862 bp and removes both the β- and δ-globin genes with a nt A deletion just after the 3′-deletion breakpoint.
We follow the HGVS sequence variant nomenclature and IUPAC standards.

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.
