This mutation results in the production of an abnormal version of beta-globin called hemoglobin S or HbS.In this condition, hemoglobin S replaces both beta-globin subunits in hemoglobin.eta thalassemia-caused by mutations in the HBB gene. Nearly 400 mutations in the HBB gene have been found to cause beta thalassemia. Most of the mutations involve a change in a single DNA building block (nucleotide) within or near the HBB gene.
