Interaction of these α-thalassemia leads to the Hb H disease, and interaction of Hb H disease with Hb E leads to complex syndromes of AEBart’s, EFBart’s, and EEBart’s diseases, with thalassemia intermedia phenotypes, commonly encountered in the region [3–6]. Here, GSTM1 is linked to beta-thalassemia intermedia.
