WebBeta-globin produced by the HBB gene, 2 subunits of the beta-globin make up half of the 4 protein subunits found in the adult hemoglobin. proteins. A balance of both alpha- and beta-globin proteins is needed to make healthy adult hemoglobin. But with beta-thalassemia, the body produces reduced or no beta-globin. WebAlpha thalassemia is caused by harmful genetic changes (mutations) in the HBA1 and HBA2 genes. These genes work together to make the alpha globin protein. Most individuals inherit two normal copies of the HBA1 gene (one from each parent) and two normal copies of the HBA2 gene.
