Detailed explanation-1: -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-2: -Genetic therapies are approaches that treat genetic disorders by providing new DNA to certain cells or correcting the DNA. Gene transfer approaches, also called gene addition, restore the missing function of a faulty or missing gene by adding a new gene to affected cells.

Detailed explanation-3: -But some inherited and acquired mutations can cause developmental disorders, neurological diseases, and cancer. Depending on what is wrong, scientists can do one of several things in gene therapy: They can replace a gene that is missing or is causing a problem. They can add genes to the body to help treat disease.

Detailed explanation-4: -Gene therapy is a technique used in an effort to treat or prevent disease. When a gene mutation (a permanent alteration in the DNA sequence) causes a protein to be missing or faulty, gene therapy may be able to restore the normal function of that protein.

Detailed explanation-5: -There are basically three types of gene therapy: ex vivo, in vivo, and in situ.
