CRISPR/Cas9-Mediated Correction of the Sickle Mutation in Human CD34+ cells

Targeted genome editing technology can correct the sickle cell disease mutation of the β-globin gene in hematopoietic stem cells. This correction supports production of red blood cells that synthesize normal hemoglobin proteins. Here, we demonstrate that Transcription Activator-Like Effector Nucleases (TALENs) and the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 nuclease system can target DNA sequences around the...
