The scientist believes that genetically manipulated twins can be "smarter"

A neurobiologist at the University of California said that twins who genetically manipulate a Chinese scientist (to make them resistant to HIV) may have mutations in their brains that make them "smarter".

"Most likely, their brains are affected," Alkino Silva told MIT Technology Review, quoted by South China Morning Post.

"The simplest interpretation is that these mutations are likely to affect the cognitive function of the twins," said the scientist whose laboratory discovered 2016 this new effect of the CCR5 gene on memory and the ability of the brain to form new connections.

According to the MIT Technology Review, several studies have shown that in addition to protecting against HIV-AIDS, deletion of the CCR5 gene is associated with cognitive improvement.

The same change, introduced into the DNA of the twins, "not only makes the mice smarter, but also improves the recovery of the human brain after a stroke," Silva said.

In November 2018, Chinese scientist Ye Jianqiu claimed to have succeeded in creating the first twins genetically engineered to confront HIV-Aids.

After a preliminary investigation, the Chinese authorities assured that He "did the investigation unlawfully to gain personal glory and profits."

"He avoids oversight, raises funds, and organizes researchers himself to conduct research into the genetic modification of human embryos for reproductive purposes, something that is prohibited by Chinese law," they added.

In a recent public statement at a conference at the University of Hong Kong in November, the scientist stressed that the study did not aim to eliminate genetic diseases but to "give the natural ability of girls" to resist a possible future HIV-AIDS infection.
