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.
