IthaID: 3434

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 87 CAC>CAG [His>Gln] HGVS Name: HBA1:c.264C>G
Hb Name: Hb Lansing-Ramathibodi Protein Info: α1 87(F8) His>Gln

Context nucleotide sequence:

Protein sequence:

Also known as:

Comments: Carriers of this variant have no apparent anaemia with low measured oxygen saturation by pulse oximetry (SpO2), whereas co-inheritance with Hb Pakse produces mild anaemia.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
