Common Name: CD 147 TAA>CAA [Stop>Gln] HGVS Name: HBB:c.442T>C
Hb Name: Hb Zunyi Protein Info: β 147, Stop>Gln; modified C-terminal sequence: (147)Gln-Ala-Arg-Phe-Leu-Ala-Val-Gln-Phe-Leu-Leu- Lys-Val-Pro-Leu-Phe-Pro-Lys-Ser-Asn-(167)Tyr-COOH

Also known as:

Comments: Reported as a de novo mutation in a young transfusion-dependent patient with severe hemolytic anaemia. This mutation results in a stop-codon substitution to a glutamine residue and an increase of 21 amino-acids in the beta-globin chain. Leads to a dominant beta-thalassemia state according to this case report.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
