Three subjects were found to have deletions in the globin gene cluster, including a beta-thalassaemia due to deletion of HBB (beta-globin gene), an HPFH due to deletions of HBD (delta-globin gene) and HBB, and an HPFH due to a novel HBG2-HBG1 fusion gene consisting of exons 1 and 2 of HBG2 ((G)gamma-globin gene) and exon 3 of HBG1 ((A)gamma-globin gene).     ///    The case with the HBG2-HBG1 fusion suggested the existence of another mechanism for the reactivation of HBG2 and HBG1.
