Hb Dapu (HBA2: c.52G > T): A Novel Nondeletional α-Thalassemia Mutation.

Abstract excerpt

We report a novel mutation on the α2-globin gene, Hb Dapu [α17(A15)Val →Phe (α2); HBA2: c.52G > T] detected in a Chinese family. This mutation gives rise to a previously undescribed hemoglobin (Hb) variant that was undetectable by electrophoretic or chromatographic methods. The combination of this mutation with an in cis deletion of a double α-globin gene resulting in a mild form of Hb H (β4) disease, is...
