IthaID: 3142



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: -α6.3 HGVS Name: NG_000006.1:g.31022_37366del6344
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The deletion spans about 6.3 kb on the α-globin gene cluster and involves deletion of the HBA2 gene, causing deficient α-globin production. The breakpoints were at 2,754 bp upstream of the α1-globin gene translation initiation codon and 2,903 bp downstream of the α1-globin gene translation termination codon.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
