Medical science has developed its treatment process in different segments that helps patients to get rid of dreadful diseases. Technological advancement has entered medical science as a model of innovation implementation to get desired results. The use of gene therapy for preventing disease can be recognised as the modern invention of medical science.

Gene Therapy

Gene therapy is the technique that uses a gene to cure, prevent or treat medical disorder. In the human body often gene therapy is conducted to transplant some missing genes, add new copies of genes to develop a healthier version of genes. Some features of Gene Therapy are the following-

1. There are three types of gene therapy such as in situ, in vivo and ex vivo. In the process of ex vivo therapy the target cells are removed from the human body to add any therapeutic gene in the body or correct the reason of the concerned disease.
2. The main purpose of gene therapy is to alter the course of disease by particularly focusing on its genetic cause. The kind of inherited disorders which may not be found by the doctors through the usual process of treatment is cured by using gene therapy. The benefits of gene therapy include treating, curing or preventing inherited disorders such as hemophilia,beta thalassemia. 
3. Gene therapy is a technique that corrects person’ genes through several mechanisms such as relaxing a diseased set of genes with a healthier alternative, inactivating a diseased gene which is not responding timely.
4. There are different types of gene therapy products such as Plasmid DNA to carry therapeutic genes into the human body. Viral vectors are the product of carrying genes into human cells through the help of viruses. Modified viruses are used by removing their ability to spread infectious disease for carrying genes.

Application of gene therapy

Gene therapy holds the process of transformation into the human body by changing a set of genes to correct any kind of disease or disorder. The disease or difficult disorders like hemophilia, thalassemia and sickle cell diseases. Gene therapy has major benefits on human body such as-

1. This therapy is life-saving and long-lasting. It can save people from a specific medical condition.
2. Though it is more expensive than other treatment methods it can cause serious side effect after treatment.
3. The development of gene therapy is targeted to cure disorders of human body and it is highly regulated by National Institute of Health. Gene therapy gives the way to modify DNA. It is considered as a kind of biological treatment. Adding a healthier version of gene into human body to replace a set of diseased gene is called gene augmentation.

In the medical science process of treatment gene therapy is quite new and experimental. It is a expensive method of treatment that cannot be afforded by most of the people. On the contrary, the success of gene therapy is quite uncertain. It has been found that one of the major cons of gene therapy is it can harm the other cells if the replaced or corrected gene get mixed into other cells other than the faulty ones. Still in the innovation way of medical science gene therapy can be recognised in recent times as a new way of approaching towards human treatment.
