Risks of Gene Therapy

admin    Gene Therapy, Risks    

There are a number of risks associated with gene therapy. In the beginning phases, there can be problems that result from the way the genes are delivered. Because delivery of the gene into the cells by a direct method is not an easy process it usually requires delivery through something known as a vector which is another word for a carrier. Viruses are the most common types of gene therapy vectors because they can identify certain cells and transport genetic material to genes within the cells. There is research currently being conducted which calls for removing the genes that cause disease from the viruses and replacing them with a particular gene that is needed to end the disease. The process next calls for the altered viruses to be inserted into the diseased cells of a person where their genetic material can be delivered. There are risks associated with this process such as:
