Genetic editing is an emerging and strong science that allows scientists to modify an extremely fundamental component of life DNA. DNA is the instruction manual that is contained in every cell of our body. In some cases, errors in this code result in illnesses.
Genetic editing provides researchers with an opportunity to correct these errors before they develop severe illnesses. Among the most renowned tools of this sort is named CRISPR-Cas9, which resembles the precision scissors that are able to cut and modify the portions of the DNA.
Currently, scientists are seeking numerous opportunities of how genetic editing may help avoid diseases in the future. To illustrate, there are inherited diseases such as sickle cell disease which can be triggered by a single gene error.
CRISPR has already been applied to treat patients with sickle cell disease and another blood disorder referred to as beta-thalassemia successfully by the scientists. These initial therapies demonstrate that someday genetic engineering will cure diseases by fixing the root cause within our DNA. After reading about such breakthroughs, I feel optimistic about the future of medicine.
The reduction of dangerous cholesterol levels through a new therapy is one of the greatest examples of how genetic editing can be used. A single gene edit, performed in a clinical study could reduce bad LDL cholesterol by approximately half, and this otherwise would require years of daily medication.

Such a strategy would save the lives of millions of individuals who die of heart diseases which is one of the major causes of death globally.
Genetic editing is also under study in the case of diseases that are not necessarily hereditary. In these tools, scientists have developed pigs that have resistance to swine fever which is a virus that kills many animals and it affects food security on people.
It demonstrates that genetic editing is not only applicable to humans and can be applied to prevent diseases in animals, as well as reduce the transmission of dangerous viruses.
Rare diseases are also another place where genetic editing can be used. Most of the rare conditions such as a severe metabolic disorder in newborns have no good treatment presently.
A recent example was that a baby with this rare disease was administered a one-on-one gene editing treatment. The genetic issue has been corrected in the therapy, which means that the baby is much healthier and will be able to grow up normally. This demonstrates that the formerly untreatable conditions may have a new hope in the form of genetic editing.
Other scientists are also examining how to apply genetic editing to prevent viruses and contagious diseases. Genetic technologies are also being researched to not only edit genes, but also to detect infections more quickly.
With CRISPR-based systems, scientists can identify viruses such as HIV and hepatitis b faster and more accurately to assist the doctor determine earlier whether a person is ill. These systems could prove to be significant in the prevention of outbreaks or identifying them at an early stage when there is a higher likelihood of treatment.
Nonetheless, genetic editing has its challenges. One big concern is safety. DNA is such an intricate material that an alteration in a single part may accidentally occur in other sections of a human being DNA.
These off-target effects may be dangerous when uncontrolled. Researchers are still working on the issue of how to ensure genetic editing is less dangerous and more precise.
Ethical concerns of using genetic editing are also quite numerous. There are those who are concerned about altering the human DNA in a manner that might be transferred to the next generations.
This type of editing is referred to as germline editing, it is controversial since there is no choice on future people whether these changes occur or not. Experts indicate that it is highly significant to create powerful guidelines that safeguard individuals, whereas science should assist in needy individuals.
Despite these obstacles, the future of genetic editing in the prevention of diseases is bright. Research is increasing at a very rapid pace and as most scientists opine, genetic editing would soon be useful in treating more widespread diseases, not just rare.
As an example, new types of editing genes such as prime editing are being developed, which are even more accurate, making a single repair of an error in the DNA and do not cut the DNA.
I get excited whenever I read such scientific discoveries since they indicate the extent to which we are studying about life at the smallest levels. At school I was taught about such diseases as cancer, heart disease, genetic disorders that happen to millions of people worldwide.
Genetic editing will not substitute all existing treatments, but it can be a potent intervention in line with vaccines, medicine, and lifestyle modifications to prevent a disease prior to its onset.
To sum up, genetic editing is not a mere concept of the future but it is already starting to save lives of both people and animals. This science can save lives of many people because it can correct the root cause of genetic diseases and enhance the current method of detecting and preventing diseases.
Genetic editing will be extremely crucial in the future, and a high ethical code and safety principles must be exercised by everyone. When this is done successfully, then in my opinion, genetic editing will be amongst the greatest tools of prevention of disease in the coming years.
