Also known as:
Comments: Position β130 (H8) is located at an internal site in the haemoglobin molecule at the base of the haem pocket. The Tyr>Asp substitution introduces a charged residue into the interior of the molecule where normally only uncharged residues can be accommodated, thus leading to instability. Associated with hemolytic anemia.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
