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.
在地中海贫血高发地区,β地中海贫血(β-thal)与血红蛋白(Hb)变异体同时存在的情况并不少见。尽管大多数β珠蛋白链变异体不会加重β地中海贫血,但有些变异体会影响准确的分子诊断。在本研究中,我们报告了一例罕见的β地中海贫血与Hb Hornchurch [β43(CD2)Glu→Lys; HBB: c.130G>A] 共遗传的病例,该病例影响了纯合子β地中海贫血的分子诊断。
