A new gene-editing technique could help treat sickle cell anemia

A new treatment for the blood disease sickle cell anemia is possible now that scientists have figured out how to repair the mutation that causes the condition. It doesn’t work all the time, but it does create hope for patients.Researchers took blood from patients from sickle cell anemia. Then, they used a gene-editing technique called CRISPR to snip out the genetic mutation and replace it with healthy DNA, as described in a study published today in Science Translational Medicine.
