Abstract
The combination of β-thalassemia (β-thal) and a hemoglobin (Hb) variant is not uncommon in regions with a high prevalence of thalassemia. Although most of the β-globin chain variants will not aggravate the β-thal, some can compromise the accurate molecular diagnosis. In this study, we present a rare case of coinheritance of β-thal and Hb Hornchurch [β43(CD2)Glu→Lys; HBB: c.130G>A], that compromises the molecular diagnosis of homozygous β-thal.
