IthaID: 3945

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: 15.8 kb deletion HGVS Name: NC_000016.10:g.163886_179768del
Hb Name: N/A Protein Info: N/A

Also known as: NG_000006.1:g.24749_40631del

Comments: The deletion spans exactly 15.883 kb on the α-globin gene cluster as determined by long-read single-molecule real-time (SMRT) sequencing. The 5' breakpoint lies in the HBZP1 gene (Chr16:163886) and the 3' breakpoint lies between the HBA2 and HBQ1 genes (Chr16:179768), removing both functional α-globin genes, HBA2 and HBA1. The proband, a 37-year-old female, displayed abnormal values of routine hematological indices.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
