Gene Therapy: Frequently Asked Questions
What is gene therapy?
Gene therapy is a treatment in which a foreign gene is introduced into the organism. This is done to save or replace a defective gene. It allows the cell to recover its ability to code a protein required for the proper functioning of the organism. Source: Marie-Odile Monchicourt – “Le genome sequencé?”, with Jean Weissenbach,

The general theory behind the therapy is that a chemical reagent is injected into the patient’s brain to transfer operative genes to replace the abnormal DNA. The functioning gene is synthetic, made in a laboratory in North Carolina. The gene is injected into the brain by using an adreno-associated virus. This was described to us as a ‘Trojan Horse’ or a vehicle for the DNA to be introduced into the cells in the brain.

Gene testing involves examining a person's DNA for some anomaly that could cause or increase the risk for a disease or disorder. The DNA usually is taken from cells in a sample of blood or occasionally from other body fluids or tissues. In addition to studying chromosomes or genes, genetic testing in a broader sense can also include biochemical tests for the presence or absence of key proteins that signal aberrant genes.

Is this like Gene Therapy?
No, gene therapy is simply delivering a gene. This approach is likely to fail for a number of reasons. Our approach could not be more different. In contrast to gene therapy, our virus products amplify themselves in cancer cells, kill them and spread to neighboring cancer cells. One major advantage of our approach (targeted oncolytic virotherapy) is that in addition to the unique mechanism-of-action, our viruses CAN be engineered to express protein therapeutics to give them an extra boost.

How does replacement gene therapy work?
Replacement gene therapy displaces a mutated gene, most often a tumor suppressor gene, and replaces it with a normal copy of that gene which function to control cell growth and division.

Does gene therapy include genetic enhancement?
Genetic enhancement does not provide therapeutic benefits. It is used for overall enhancement of the genetic make up, like changing the physical characteristics. Pre-implantation genetic diagnosis, to the select the gender of an embryo.

What are the different types of gene therapy?
Somatic cell gene therapy is conducted on the somatic cells (a non-reproductive cell). Germ line gene therapy is performed on reproductive genes (germ line cells) and the goal is to correct the individual's, and their offspring's, genetic defect.

What is gene therapy and is it available now?
Gene therapy is a new approach to stem cell transplantation. Instead of finding a donor who is enough of a match to your child to donate bone marrow stem cells or umbilical cord blood stem cells, the transplant is done using the child’s own cells. The appropriate cells are removed from the patient with ALD, the correct genetic sequence is inserted into those cells, and they are then put back into the patient. ...

Knockout gene therapy aims at the products of oncogenes (genes that can stimulate the formation of a cancerous tumor). The goal in this type of gene therapy is to render the cancerous cells inactive, while also decreasing the growth of cancerous cells.
Is gene therapy an option here?
We know too little about this possible line of treatment for even life-threatening conditions as yet. As the man says - "Don't even go there"! As a matter of interest, once the teeth are formed there is presently nothing (a probably theoretically nothing! ) that can be done to alter their structure. So any attempt would have to work in the earliest years. Science fiction at present I'm afraid.

Who was the youngest child treated with Gene Therapy for Canavan disease?
Max Randell made medical history in September 1998 when he became the youngest person in the world to receive
experimental gene therapy for a neurodegenerative disease. Max was one of four children (of 15 treated) to generate new myelin as a result of this trial. All the participants showed quality of life improvements.

What scientific developments led up to gene therapy?
One crucial step in the evolution of gene therapy occurred in the early 1950s, when James Watson and Francis Crick elucidated the structure of DNA. Other major steps included the cracking of the genetic code in the 1960s and the discovery in the 1970s of restriction enzymes, which enabled researchers to isolate specific genes from DNA and to begin to develop recombinant DNA (gene-splicing) technology. During the 1980s, gene transfer systems using retroviruses and lymphocytes were first developed. ...

How long will it be until gene therapy is widely available?
No one knows for sure, but within the next decade, genetic science will move closer toward finding treatments for various diseases. Help for people with cystic fibrosis, hereditary anemias and immune system disorders may become available within the next few years. Other problems that could become treatable include very high inherited levels of blood cholesterol, other errors of metabolism and juvenile diabetes.

Why are the viruses used in gene therapy referred to as "vectors"?
One meaning of the word "vector" is "carrier. " In the field of infectious diseases, the term has been used to describe an agent, such as an insect, that carries an infectious organism from one individual to another. By analogy, the genetically disabled viruses used in gene therapy are referred to as vectors because they carry genes to cells. Most often, these vectors are derived from mouse retroviruses.

What would be the advantage of germ-line gene therapy?

How could gene therapy be used to treat AIDS?
Gene therapy could be used to make immune cells resistant to HIV (the AIDS virus). It could also be used to help patients destroy HIV and HIV-infected cells by increasing the body's immune response to these elements. Results from the ADA trial support the idea that genetically altered lymphocytes or stem cells might help prevent immune system failure in AIDS patients. T-lymphocytes enhanced with genes that block the spread of HIV could be tested in humans soon.

Are there ethical issues associated with gene therapy?
Yes, gene therapies can potentially be used for non-medical applications, like eye color, skin color, and athletic ability. So the question of who decides what genes are desirable and which are not becomes an issue. Gene and cell therapies have tremendous potential to improve the quality and length of life. In developing these therapies, scientists must adhere to the highest ethical standards, follow the rule of law, and use sound scientific practices and principles.

What is gene therapy and how does it work?
Gene therapy is one possible treatment of mesothelioma cancer. By replacing, removing, or otherwise altering the expression of a person’s genes, the disease is treated on a cellular level. The overall aim of gene therapy is to help compensate for abnormal genes, and to possibly introduce healthy, functional genes into the patient.
How close are we to a cure of primary immune deficiency through gene therapy?
