Although gene therapy is a promising treatment option for a number of diseases (including inherited disorders, some types of cancer, and certain viral infections), the technique remains risky and is still under study to make sure that it will be safe and effective.

Gene therapy has some potential risks. A gene can’t easily be inserted directly into your cells. Rather, it usually has to be delivered using a carrier, called a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells’ genes.

Because people who would be affected by germline gene therapy are not yet born, they can’t choose whether to have the treatment. Because of these ethical concerns, the U.S. Government does not allow federal funds to be used for research on germline gene therapy in people.

A single intravenous infusion costs $2.1 million per patient. Blue Cross Blue Shield of Massachusetts, the state’s largest health insurer, has covered Luxturna for two patients since 2018 and Zolgensma for two patients in 2019.

There are two different types of gene therapy depending on which types of cells are treated:

• Somatic gene therapy: transfer of a section of DNA to any cell of the body that doesn’t produce sperm or eggs.
• Germline gene therapy: transfer of a section of DNA to cells that produce eggs or sperm.

Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene.

Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

The basics of the process are the identification of the gene in question, duplication of that gene, and insertion of the gene into the human genome needing the gene (CIS) . The gene that needs to be altered or replaced must be identified.

Possible Effects of Gene Therapy Such trials usually last 2 to 4 years and go through several phases of research. In the United States, the U.S. Food and Drug Administration (FDA) must then approve the new therapy for the marketplace, which can take another 2 years.

The first steps following gene discovery have become somewhat routine: completing sequencing of the gene, matching the sequence to a known protein pattern (if possible), deciphering gene expression through tissue and ti.

French Anderson, MD, was “dubbed ‘the father of gene therapy’ after a team he led in 1990 cured a hereditary disease of the immune system in a 4-year-old girl.” That’s not quite the way it happened.

After extensive research on animals throughout the 1980s and a 1989 bacterial gene tagging trial on humans, the first gene therapy widely accepted as a success was demonstrated in a trial that started on 14 September 1990, when Ashanthi DeSilva was treated for ADA-SCID.

Cell and gene therapies are designed to halt a disease in its tracks or reverse its progress rather than simply manage symptoms. These are often one-time treatments that may alleviate the underlying cause of a disease, and they have the potential to cure certain conditions.

Gene therapy involves the replacement or modification of a genetic variant to restore or enhance cellular function or the improve response to nongenetic therapies. Genetic engineering involves the use of recombinant DNA techniques to introduce new characteristics or traits.

Potential Harms to Human Health

• New Allergens in the Food Supply.
• Antibiotic Resistance.
• Production of New Toxins.
• Concentration of Toxic Metals.
• Enhancement of the Environment for Toxic Fungi.
• Unknown Harms.
• Gene Transfer to Wild or Weedy Relatives.
• Change in Herbicide Use Patterns.

Gene therapy is an experimental form of treatment that uses gene transfer of genetic material into the cell of a patient to cure the disease. The idea is to modify the genetic information of the cell of the patient that is responsible for a disease, and then return that cell to normal conditions.
