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.

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.
