Victoria Gray has sickle cell disease (SCD). SCD is a genetic disease that causes red blood cells to be half moon-shaped instead of round. The sickle-shaped cells block blood vessels, slowing or stopping blood flow. This causes sudden, severe pain. Complications include organ damage, strokes, anemia, and early death.The disorder is caused by a gene mutation in a specific type of stem cell. Stem cells produce the cells that we use and pass genes to them. A process known as CRISPR-Cas9 has been used to correct the harmful mutation in lab equipment. In clinical trials, the edited cells have been placed in the bodies of people with sickle cell anemia.
