RESUMEN
The population of Viet Nam, is 96.2 million, of which 13.8% are carriers of thalassemia genes. Thalassemia/hemoglobinopathies carriers exist at different frequencies in all 54 ethnic groups of the country. Gene carrier rate and globin gene mutation rate varies ethnically and topographically. The ethnic groups in the Northern Highland region have high rates of α0- and ß0-thalassemia (α0- and ß0-thal), while those in the Southern Middle region have high rates of α+-thalassemia (α+-thal) and Hb E (or codon 26) (HBB: c.79G>A). The lowest is found in La Hu (0.23%), while the highest is found in Raglai (88.6%). Thalassemia prevention and control programs were introduced using prenatal and neonatal diagnosis for the prevention of new thalassemic births. Most existing thalassemia patients are undergoing supportive treatment with regular blood transfusions and iron chelation. Curative treatment by hematopoietic stem cell transplantation is available but is limited to a minority of the patients.
