The world’s first gene edited babies may have had their brains unintentionally changed and possibly subjectively improved, as a result of contentious treatment carried out by a team of Chinese scientists. Many of you might not be aware of the fact that Chinese scientist named He Jiankui used gene-editing technology CRISPR to genetically alter two embryos. He was working with the embryos of families belonging to HIV positive parents. He wanted to change the genes of the babies so that they can become more resistant to the disease.
Dr He Jiankui and his team allegedly deleted a gene from a number of human embryos before inserting them in the womb of the mothers. However, this experiment was greeted with horror. But with the successful birth of two babies Lulu and Nana doesn’t end the controversy. It seems that there might be other effects of the alteration. It appears as if the twin babies Lulu and Nana might be even smarter and they can also recover from strokes, mainly because of the genetic modification. In short the after-effects of strokes even revealed a positive result as it disclosed a fast recovery rate.
According to MIT Technology Review, scientist Jiankui deleted the gene named CCR5 from the embryos in order to create children who are immune to infection by HIV. However, another research which was recently published in another journal disclosed that the deletion of the gene in mice lead to the possibility of enhanced mental cognitive function.
Although some time might be taken to understand the impact of erasure of the gene in the babies and if the effects noted on mice would also become applicable to humans.
While developing humans who are smarter and more easily able to restore from the effects of strokes seems like a good plan, there are plenty of moral complications connected with genetic alteration in humans.
