The possibilities of gene therapy hold much promise. To date, however, that promise has not been realized.
Clinical trials of gene therapy in people have shown some success in treating:
- Severe combined immune deficiency
- Blindness caused by retinitis pigmentosa
But, several significant barriers stand in the way of gene therapy becoming a reliable form of treatment, including:
- Finding a reliable way to get genetic material into cells
- Reducing the risk of side effects
- Targeting the correct cells
Gene therapy continues to be a very active area of research.
