NEW YORK (Reuters Health) - Changes in the DNA of Chinese infants may also affect their brains, a new study showed. Will Lulu and Nana's twin students be very superior and very smart?

The birth of these two Chinese children shocked and sparked controversy in the global scientific community late last year when researcher Hee Jankui of the Shenzhen University of Science and Technology surprised the whole world by announcing on YouTube the birth of the first two genetically modified children using Cresper "He said.

The researcher said he changed the CCR5 gene to make girls resistant to HIV if they were infected as a result of parental transmission. However, new research shows that this change to DNA may also affect children's brains.

The CCR5 gene plays a key role in memory and the brain's ability to form, and his laboratory tests in 2016 showed that removal of the gene, said Alessino J. Silva, a neuroscience expert at the University of California, Los Angeles, in an article in the Massachusetts Institute of Technology. Of rats greatly improves memory.

Prediction is impossible
Since then, subsequent research has shown that people who naturally break the CCR-5 gene are rapidly recovering from vascular and brain defects and have better school outcomes.

"The simple explanation is that these mutations are likely to have an impact on the cognitive function of the twins," says the neuroscientist. "It is impossible to predict the precise impact on the cognitive abilities of the twins, and for this reason he thinks such a process should not be done.

As a result, some scientists now wonder whether the real goal of Giancoe's experience is superior intelligent beings, believing it may be so as part of a race for excellence in biotechnology between nations, especially the United States and China.

The experience of the Chinese team has been largely condemned, and Giancoi, now named by the Chinese press, is being investigated by Frankenstein, who is accused of falsifying "moral evaluation documents" after he was dismissed from his university.
