Gene psychiatric help?
What are 4 obstacles to use of gene psychotherapy in Medicine?
Answer:
1. Gene labour tools. Genes are inserted into the body using gene carriers call vectors. The most common vectors presently are viruses, which hold evolved a way of encapsulating and deliver their genes to human cells contained by a pathogenic manner. Scientists rub the genome of the virus by removing the disease-causing genes and inserting the therapeutic genes. However, while virus are effective, they can introduce problems similar to toxicity, immune and inflammatory responses, and gene control and targeting issues.
2. Limited experience of the functions of genes. Scientists currently know the functions of only a few genes. Hence, gene psychoanalysis can address only some genes that raison d`¨ētre a particular disease. Worse, it is not certain exactly whether genes have more than one function, which creates dawdling as to whether replacing such genes is indeed desirable.
3. Multigene disorders and effect of environment. Most genetic disorders involve more than one gene. Moreover, most diseases involve the interaction of several genes and the environment. For example, many population with cancer not just inherit the disease gene for the disorder, but may have also bungled to inherit specific tumor suppressor genes. Diet, exercise, smoking and other environmental factors may hold also contributed to their disease.
4. High costs. Since gene therapy is relatively strange and at an experimental stage, it is an expensive treatment to undertake. This explains why current studies are focused on illnesses commonly found contained by developed countries, where more ethnic group can afford to pay for treatment. It may lift decades before developing countries can pilfer advantage of this technology.
