20 Advantages and Disadvantages of Gene Therapy
Gene therapy is a medically-based practice that uses normalized genetics to replace genes which are either not present or abnormal for some individuals. Doctors would take the specific gene sequences that need adjustment, and then insert them into the cellular information of the patient in various ways. Most forms of gene therapy are still in the clinical research stage, but there have been stories of encouraging results. Several inherited immune deficiencies are being treated successfully right now with gene therapy. When the blood stem cells are removed from patients, retroviruses then deliver working copies of the defective genes to the body. For the gene therapy options which have been approved for use, there are many success stories to consider. Sebastian Misztal is one such story.
Gene Therapy Pros and Cons
Gene therapy is an experimental treatment using genetic material to treat or prevent certain diseases. While not yet widely available, gene therapy may one day help doctors treat diseases by directly replacing the disease-causing gene. Luxturna treats certain inherited retinal eye diseases. Gene therapy works by replacing or inactivating disease-causing genes. In some cases, gene therapy introduces new genes into the body to treat a specific disease. With gene therapy, doctors deliver a healthy copy of a gene to cells inside the body. This healthy gene may replace a damaged mutated gene, inactivate a mutated gene or introduce an entirely new gene.
Gene therapy is a medical technique which utilizes specific, normalized genes to replace the genes that are abnormal or not present in an affected individual. The goal of gene therapy is to correct a disorder caused by missing or abnormal genes. Although the processes of gene therapy are still at an experimental stage, the results achieved have been quite encouraging. Since the s, about 2, clinical trials involving gene therapy have conducted worldwide. The largest number of active gene therapy clinical trials occurred in , with being conducted.
Posted by Biolyse Nov 3, Gene Therapy 0. Over the years genetic disorders and gene-related illness have been responsible for high mortality rates and reduced quality of life. Some of the congenital abnormalities manifest quite early, and there are minimal hopes for survival in these children, this causes much pain to their families because management option is limited and there is very little at their disposal to modify such conditions. Scientists are developing a relatively new technique that will give hope to the hopeless and make life better. Genetic disorders can be due to misalignment, missing genes or excess of a gene. Genetic therapy works at the elementary level of heredity to replace the defective genes with new ones.
Towards New Therapies for Parkinson's Disease. The use of levodopa L-3,4-dihyroxyphenylalanine as a symptomatic therapy was established nearly 50 years ago and continues to be an important approach in early and late disease Fahn Although the majority of patients initially respond well to dopaminergic therapies, many eventually develop fluctuations in their therapeutic response, often with associated dyskinesias Jenner

Gene therapy is an experimental technique in medical science that uses genes to either prevent or treat disease. There are several different approaches to gene therapy being researched today. One method involves the replacement of a mutated gene with a healthy copy of it.
