7.1. Gene-therapy medicines
These medicines contain genes that have a therapeutic effect - they act to treat the disease. They work by inserting ‘recombinant’ genes into cells. Sometimes they use a virus (called a ‘vector’) to deliver the genes.
- A recombinant gene is a stretch of DNA that is created in the laboratory to have a certain sequence.
- When the gene is delivered into a cell, it causes the cell to either produce, or stop the production of a specific protein. By doing this, it can slow down or cure a disease.
- Diseases that have so far been targeted by gene therapy include genetic disorders, cancer and chronic (long-term) conditions.

If the treatment is successful, the new gene will make a functional protein to treat a disease.
