摘要: The major disorders of β-globin, sickle cell disease and β-thalassemia, may be ameliorated by expression the fetal gene paralog γ-globin. Uncertainty regarding mechanisms repressing hemoglobin in adult stage has served as a puzzle developmental regulation well barrier to rational therapeutic design. Recent genome-wide association studies implicated zinc-finger transcriptional repressor BCL11A regulation. Extensive genetic analyses have validated potent level. Studies exemplify how contextual often substrate for trait-associated common variation. These discoveries suggested novel approaches β-hemoglobin including genome editing.
