From this cross-sectional survey, we even found three cases of thalassemia disease, including one participant with the AEBart’s disease (genotype: –SEA/− α3.7, βΑ/βΕ), and two patients with β-thalassemia/Hb E disease [genotypes: (αα/αα, β−28/βΕ) and (αα/− α3.7, β−28/βΕ)]. The gene discussed is GSTM1; the disease is thalassemia.
