PATHOLOGY

Detailed explanation-1: -They can replace a gene that is missing or is causing a problem. They can add genes to the body to help treat disease. Or they can turn off genes that are causing problems.

Detailed explanation-2: -Genetic therapies hold promise to treat many diseases, but they are still new approaches to treatment and may have risks. Potential risks could include certain types of cancer, allergic reactions, or damage to organs or tissues if an injection is involved. Recent advances have made genetic therapies much safer.

Detailed explanation-3: -Gene therapies are being used to treat a small number of diseases, including an eye disorder called Leber congenital amaurosis and a muscle disorder called spinal muscular atrophy. Many more gene therapies are undergoing research to make sure that they will be safe and effective.

Detailed explanation-4: -Although it is widely agreed that Parkinson’s is not usually inherited through the genes our parents pass on, researchers believe that gene therapy will one day be able to prevent the death of dopamine-producing cells in the brain and help to revitalise dying cells in the early stages of the disease.
