Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | French West-Indies deletion/insertion | HGVS Name: | NG_000007.3:g.57155_80887delinsCAGCAGGAAAGTGAGAAG |
| Hb Name: | N/A | Protein Info: | deletion of 23728 nts from the δ gene to β gene |
Also known as: French West-Indies HPFH deletion
Comments: Found in a heterozygous state in a female with a normal haematological phenotype. The deletion spans approximately 23730 bp and removes both the β- and δ-globin genes with insertion of 18 nucleotides (CAGCAGGAAAGTGAGAAG) in the deletion junction. Found in combination with HbS in the mother (hence, hemizygous), presenting a very similar hematological phenotype except for the presence of HbS.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
