Abstract
We report a novel α2-globin chain hemoglobin (Hb) variant in a 23-year-old female of Chinese Han nationality. The Hb variant can be detected by glycated Hb electrophoresis (CapillaryS2, Hb A1c program). However, Hb fractions analyzed by capillary electrophoresis (CE) (CapillaryS2, Hb program) and high performance liquid chromatography (HPLC), (VARIANT II™ β-Thalassemia Short Program) showed no suspicious Hb variant. Sanger sequencing revealed a novel mutation [α67(E16)Thr→Ile, HBA2: c.203C>T]. We named this novel variant Hb Sichuan after the geographic origin of the proband.
