Crispr sickle cell anemia.
I have a long-standing interest in sickle cell anemia, a genetic abnormality that is the scourge of approximately 100,000 Americans, primarily Black, who are afflicted with it. Sickle cell disease (SCD) is an inherited disorder marked by abnormal hemoglobin, the protein that delivers oxygen to the cells of the body.
