Gene therapy is a medical treatment that involves altering the genes inside a patient’s cells to treat or cure a disease. The goal of gene therapy is to replace, repair or enhance a patient’s defective or missing genes in order to treat or cure a disease. This is achieved by introducing new genes into a patient’s cells, modifying existing genes, or removing faulty genes. Gene therapy is a promising area of medicine with the potential to treat a wide range of genetic disorders, such as cystic fibrosis, sickle cell anemia, and hemophilia, among others. However, gene therapy is still in the early stages of development and research, and there are still many challenges and risks associated with the technology.
