Comments: Found as a novel Hb variant in a 33-year-old Chinese male with normal hematological parameters (Hb 16. 0g/dL, RBC 5.54×10^12/L, MCV 88.6 fL, MCH 28.9pg). No clinical presentation. Detected by capillary electrophoresis at Z6 zone. Splitting of the Hb A2 peark into two fractions (Hb A2 and Hb A2-Liangqing on the capillary 2 Flex Piercing device). The results of patient are as follow: Hb A 97.4% ,Hb F 0%, Hb A2 1.5%, Hb A2-Liangqing 1.1%.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
