CRISPR genetically-modified girls ‘given ENHANCED brains’, warn scientists

The goal was to make the girls immune to infection by HIV, the AIDS causing virus.

And new research shows that the same alteration introduced into the girls’ DNA, deletion of a gene called CCR5, could be linked to greater success in school.

Alcino J. Silva, a neurobiologist at the University of California said: “The answer is likely yes, it did affect their brains.”

“The simplest interpretation is that those mutations will probably have an impact on cognitive function in the twins,” says Silva.

He says the exact effect on the girls’ cognition is impossible to predict, and “that is why it should not be done.”
