In the world of science, gene editing is being considered the biggest medical revolution of the future. Scientists hope that by correcting the defects in DNA, treatment of many serious diseases will be possible. But a case that has come to light from China is raising big questions on the danger and safety rules of this technology. Here a 6-year-old girl died after experimental gene editing therapy. His family had spent about 8 lakh dollars (about more than Rs 7 crore) on this treatment.
According to the report, the girl had a rare genetic disease, due to which her mental development was being affected. To cure it, scientists had developed such gene therapy, the aim of which was to change the bad genes present in the brain cells. During the treatment, billions of virus-based vectors (vectors) were given to the girl through the spinal cord, so that they could reach the brain and make changes in the genes. But he died after about a week of treatment.
Attempt to cure through gene editing
In gene editing technology, scientists try to change or improve the bad part present in a person’s DNA. It is being used at research level for the treatment of many genetic diseases. However, such experiments on humans are still considered extremely sensitive because there are many risks associated with its results. In the case of the girl, the goal of the scientists was to correct the defective genes present in her body, so that the problems related to her development could be improved. But after treatment his condition deteriorated and he died.
Questions arising on research
This case has also raised concerns because according to reports, the information about the girl’s death was not revealed publicly. Later this matter came to light through investigation reports. The concerned medical institution has said that a special team will be formed to investigate the incident and action will be taken on the basis of investigation. Experts say that experiments in new medical technologies are necessary, but in such treatments on children, safety, knowledge of risks and adherence to ethical rules are most important.
warning to the world
China has already been in controversies regarding gene editing. In 2018, Chinese scientist He Jiankui claimed to have gene edited children, after which the scientific community across the world raised questions about safety and ethics.
What is gene editing?
Every cell of our body contains DNA, which contains information about the functioning of the body. If there is a defect in a person’s DNA, it can cause disease. Gene editing is a technique in which scientists try to change or repair damaged parts of DNA, so that the disease can be controlled. This is considered one of the biggest medical discoveries of the future.
