This technique is known as gene therapy. The healthy gene is inserted into the cells using a variety of methods, such as using a viral vector or directly injecting the gene into the cells. Once the healthy gene is inserted, it can produce the functional protein that was missing or defective in the cells, correcting the underlying genetic disorder. Gene therapy has the potential to treat a wide range of genetic diseases and disorders, but it is still a relatively new field with ongoing research and development.
