Combination of Hb Heze [β144(HC1)Lys→Arg; HBB: c.434A>G] and β-Thalassemia in a Chinese Patient with β-Thalassemia Intermedia.

We first report a novel β chain variant, Hb Heze [β144(HC1)Lys→Arg; HBB: c.434A>G], in a Chinese family. Heterozygous inheritance of the mutation results in a mild β-thalassemia (β-thal) phenotype, whereas compound heterozygosity of Hb Heze with β-thal appears as the cause of β-thal intermedia (β-TI) in our case.
