Also known as:

Comments: Unstable Hb variant found as a heterozygote in a female patient with a history of hemolytic anaemia and low oxygen saturation. The oxygen affinity of the variant was not measured. It is located in the heme pocket of the β-globin chain.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
