IthaID: 2419



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: Senegalese δ(0)β(+) HGVS Name: NG_000007.3:g.(63154_63209)_(70570_70625)del7417
Hb Name: N/A Protein Info: deletion of 7417 nts from the δ gene to β gene

Also known as:

Comments: The new δβ hybrid gene is expressed at low level, very likely due to the weak δ-globin promoter.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
