Abstrakt: Fetal hemoglobin (HbF) is abundant in the late stage fetus and newborns, but is progressively lost over the first 6 months of life as the genes encoding the g-globin subunit of HbF are repressed. HbF expression can provide clinical benefit to patients with deficient or defective b-globin, for example in β-thalassemia and Sickle Cell Disease (SCD), respectively. CRISPR-Cas9 technology offers a unique treatment modality that can be used to ex vivoedit regulatory DNA sequences in patient CD34+hematopoietic stem and progenitor cells (HSPC) containing hematopoietic stem and progenitor cells in order to upregulate HbF. Reinfusion of edited CD34+HSPC would be expected to lead to the production of erythrocytes expressing high levels of HbF, and amelioration of disease.
