Can CRISPR cure genetic diseases today?
Yes, we are already seeing promising results for certain genetic diseases. For example, CRISPR-based therapies for sickle cell disease and beta-thalassemia have shown success in clinical trials by editing patients' own blood stem cells to produce fetal hemoglobin. In 2023, the UK approved Casgevy, a CRISPR therapy for these conditions. However, we must be realistic: this is not a universal cure for all genetic diseases. Delivery remains a challenge—getting the CRISPR components into the right cells, like neurons or liver cells, is complex. Also, many diseases involve multiple genes or environmental factors. Our discovery was a result of curiosity, not a targeted goal, and the path from lab to clinic takes time. I am optimistic, but we must proceed carefully, ensuring safety and equity in access.
