DNA editing is still too dangerous to be used in humans
Does CRISPR technology increase mortality? - life short science news

You may remember that a Chinese scientist has applied a gene-editing technique called CRISPR in two human baby girls in 2018. Apart from ethical issues, there is now also concern that the genetic mutation that was introduced into the girls to protect them against HIV, is actually doing more harm than good.

Researchers have now associated this mutation with a 21% increase in mortality later in life. This association is based on the analysis of 400,000 genomes and linked health records contained in a British database, the UK Biobank.

Researchers conclude that CRISPR is still a far too risky technique to employ in humans, because health effects of many genes and gene mutations are largely unknown.
