Comments: Found in a 25-year old Chinese man presented with mild anaemia. This mutation in combination with the Southeast Asian --SEA deletion [IthaID:309] found in proband’s unborn child. The fetal cord blood showed a peak for Hb Barts indicating that the fetus had Hb H disease.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
