Also known as:
Comments: Found in a heterozygous state. Presented with cyanosis at birth. Although Hb-F Circleville occurs due to a leucine replacement at residue 63, where the distal histidine is located, and causes clinical symptoms that are similar to Hb F-M Osaka [IthaID: 1433], it will be necessary to measure methemoglobin to name this variant an new M Hb.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
