Why is germ cell therapy banned

However, for many, this is where they feel the benefits of germline gene therapy stop. Germline gene therapy is currently not legal in the UK because the risks still appear to outweigh the benefits. Somatic gene therapy is when DNA is transferred into body tissues. So, do the ethical issues associated with germline gene therapy make it unacceptable? Or, is it just the lesser of two evils when compared with the impact of some genetic diseases? Read some of the arguments for and against, and see what you think….

Gene therapy is when DNA is introduced into a patient to treat a genetic disease. The new DNA usually contains a functioning gene to correct the effects of a disease-causing mutation. Some children with severe combined immunodeficiency SCID , a genetic disorder characterised by a reduced number of immune cells, have been treated using gene therapy. Cystic fibrosis is a relatively common genetic condition in which the lungs and digestive system become clogged with thick, sticky mucus.

Read some of the arguments for and against, and see what you think… Do the potential benefits of germline gene therapy outweigh the potential risks? Yes Germline gene therapy enables the correction of disease-causing mutations that are certain to be passed on from generation to generation, sparing future generations from suffering from the disease.

It enables the generation being treated to lead a healthy life. No The effects of gene therapy are too unpredictable. When I was a medical student during the s, bone marrow transplantation was being performed in only a few institutions and as a last resort, and the success rate was abysmal. But the discovery of potent immunosuppressants and other technical advances improved the success rate markedly, and bone marrow transplants are now routine in many institutions.

There are many similar stories in medicine, including open-heart surgery and organ transplants, which were remarkably primitive in their earliest incarnation, but which are usually uneventful now. The reality is that successful innovation is impossible without continual learning and incremental improvements by users, and in medicine, it is in clinical settings that this process must occur.

Maybe it has been a while since Dr. Daley has seen a patient like one I remember well—a year-old with sickle-cell anemia who had suffered three strokes, been crippled by repeated bone and joint infarctions, and had become a Demerol addict due to the unrelenting pain from the arthritis that resulted.

And at the very least, we must not let skepticism about potential applications that would modify humans interfere with research-based germ cell editing. It may be ethically warranted to intervene with as yet unproven therapies in dire situations when there are no alternatives. Ironically, much of the controversy about moratoriums may be moot because, in effect, Appendix M of the NIH Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules already creates a near-absolute moratorium on germline gene therapy in the United States:.

Nor is there likely to be much interest in germline therapeutic interventions by companies, given the uncertainty about how the FDA might regulate these technologies, concerns about opposition from the public and from the academic scientific community, and uncertain economic prospects.

In effect, a moratorium is already in place. Given that the committee can reject any proposal for any reason, its unwillingness even to consider an entire category of clinical studies seems unnecessarily intransigent and arbitrary. Sound and humane public policy would see the NIH RAC repeal Appendix M and announce its intention to consider carefully crafted human germline gene therapy proposals that meet community standards for risk-benefit.

Scientists do not derive these stem cells from embryonic stem cells. As a result, this technique does not have the same ethical concerns.

With this and other recent advances in stem cell technology, attitudes toward stem cell research are slowly beginning to change. However, other concerns related to using iPS cells still exist.

This includes ensuring that donors of biological material give proper consent to have iPS cells extracted and carefully designing any clinical studies. Researchers also have some concerns that manipulating these cells as part of stem cell therapy could lead to the growth of cancerous tumors.

Although scientists need to do much more research before stem cell therapies can become part of regular medical practice, the science around stem cells is developing all the time. Scientists still conduct embryonic stem cell research, but research into iPS cells could help reduce some of the ethical concerns around regenerative medicine.

This could lead to much more personalized treatment for many conditions and the ability to regenerate parts of the human body. Learn more about stem cells, where they come from, and their possible uses here.
