Hemoglobinopathies constitute the most frequent monogenic disorders worldwide and are caused by gene mutations that affect the synthesis of the normal hemoglobin chains or contribute to structural changes of the Hb molecule. In Greece hemoglobinopathies are the most frequent genetic diseases and the Greek National Prevention Program for Thalassemia and other Hemoglobinopathies is the most typical international example of a voluntary prevention screening program. During a 20-year study period, gene interactions in 437 pregnancies were related with risk of β-thal major, sickle cell disease and Hb Bart’s hydrops fetalis. 437 prenatal diagnoses were performed and (22.2%, N=97) fetuses were homozygotes or compound heterozygotes for clinically significant mutations. The couples were informed of all the currently available therapeutic approaches for β-TM or sickle cell disease. The decision for the termination or continuation of the pregnancy was left to parental choice and the termination of the pregnancy was generally accepted and 91 from 97 affected pregnancies were terminated. The “success” of a prevention program depends on the commitment and the will of the governments, the consolidation of strong educational campaigns, the continuing public education and health professional awareness, the existence of reliable laboratories. Greek National Bioethics & Techno ethics Committee gives a framework about the bioethical questions arising as well as the “Bio laws” in the Greek constitution. In our constitution the availability of prenatal diagnosis, the social bioethical framework as expressed by the National Bioethics committee, the contemporary role of religion in public life (Greek Orthodox Church less influential) and the existing legal frame of the termination of pregnancy in cases of severe hemoglobinopathies contributed to the success of the Prevention programme.
