IthaID: 371



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 39 (-ACC) [-Thr] HGVS Name: HBA1:c.118_120del
Hb Name: Hb Taybe Protein Info: α1 39(C4) Thr->0

Context nucleotide sequence:
CAGGATGTTCCTGTCCTTCCCCACC [ACC/-] AAGACCTACTTCCCGCACTTCGACC (Strand: +)

Also known as:

Comments: This deletion results in a structural abnormality that affects the α1β2 contact and the α1β1 interface, producing a highly unstable Hb. Moderate to severe haemolytic anaemia in the homozygote or compound heterozygote state. Normal clinical phenotype in the heterozygote state.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
