The hemoglobinopathies encompass a heterogeneous group of disorders associated with mutations in both the alpha-globin and beta-globin genes. Non-sickling disorders are found primarily in individuals of Mediterranean, Asian and Southeast Asian ancestry. With rapid growth in the Asian and Hispanic segments of the US population, the geographic distribution of hemoglobinopathies is expected to become significantly different from what it is today. The epidemiologic changes in the prevalence of non-sickling hemoglobin disorders have important implications for future public health programs, including newborn screening. The purpose of newborn screening for hemoglobinopathies is to identify clinically significant disorders and provide early education and specialized care prior to the onset of clinical symptoms. Although newborn screening for sickle cell disease is mandated in all states, screening for non-sickling hemoglobinopathies is directed in only one state and limited to reporting of a presumptive diagnosis in most other states. Early delivery of comprehensive care, as well as new and potentially curative therapies, has significantly improved the prognosis for affected patients. This review will consider the increasing prevalence of once uncommon hemoglobinopathies in the US, highlighting the rationale for expanding newborn screening beyond sickle cell disorders.
