Also known as:

Comments: Found in three heterozygous clinically asymptomatic Malay cases presented with Hb range 11.7-14.8 g/dL, MCV 69.1-80.8 fL and MCH 24.5-26.8 pg. CE shows normal level of HbA2 and an abnormal peak (9.3-18%) at zone 7. HPLC shows no abnormal peak with normal Hb F level. The mutation also reported in compound heterozygosity with SEA deletion [IthaID: 309]. The patient presented with reduced Hb 8.0 g/dL, MCV 62.1 fL and MCH 19.3 pg. CE shows abnormal Hb 30.9 % at zone 7 and HbH 5 %. Normal level of HbF detected with HPLC.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
