Invasion of the human gene code is a controversial issue that has its supporters and opponents. Specialists studying the human genetic set open up wide opportunities for overcoming numerous incurable diseases. So the well-known geneticist from China, He Jiankui, without permission, changed the genome of children, making their body immune to deadly HIV. Biologist Denis Vladimirovich Rebrikov from the Russian National Research Medical University named after N. I. Pirogov developed a methodology for changing human genes to overcome congenital deafness. This problem usually plagues families in which both parents lack hearing. These unions have a very high probability of having deaf children. For the experiment, the doctor selected five couples who voluntarily agree to edit the genome. However, given the ambiguous attitude to such experiments, both among physicians and the public, Rebrikov wants to receive approval from officials for conducting experiments to correct genes. It is noteworthy that the experiment will be held in open mode, and all results will be available to the scientific community. If successful, the doctor will perform a miracle and open up the opportunity for the full development of children doomed by nature to complete silence.
