Disorders resulting from HBB (β-globin) gene mutations, mainly sickle cell disease (SCD) and β-thalassemia, become symptomatic postnatally as fetal γ-globin expression from two parologous genes HBG1 and HBG2 falls and adult β-globin increases, thereby shifting red blood cell (RBC) hemoglobin from the fetal (HbF, α2γ2) to adult form (HbA, α2β2). These disorders are alleviated when postnatal expression of fetal γ-globin is maintained. For example, in hereditary persistence of fetal hemoglobin (HPFH), a benign genetic condition, mutations attenuate γ-to-β switching, causing high-level HbF expression throughout life. Co-inheritance of HPFH with β-thalassemia or SCD mutations alleviates their clinical manifestations. Here we performed CRISPR-Cas9-mediated genome editing of human blood progenitors to mutate a 13-nucleotide HBG1/HBG2 promoter sequence, thereby recapitulating a naturally occurring HPFH-associated mutation. Edited progenitors produced RBCs with increased HbF levels that were sufficient to inhibit pathological hypoxia-induced RBC morphology of SCD. Our findings identify a potential DNA target for genome editing-mediated therapy of β–hemoglobinopathies.
