What if faulty genes in your DNA could be easily corrected, avoiding the ravages of diseases like cystic fibrosis or certain cancers?
That is the promise of gene editing, a new technique being heralded as an enormous advancement in genetic engineering.
Scientists say its speed, efficiency and cost-effectiveness make it an excellent tool for replacing rogue genes that cause human suffering and early death.
But worries about the technology’s darker side have mounted ever since Chinese researchers in April reported results of an experiment to edit a defective gene in a human embryo. For ethical reasons, researchers say they used an abnormal embryo.
The team concluded that gene editing isn’t yet sufficiently reliable and precise enough to apply the technique in humans.
Nevertheless, some scientists and bioethicists worry that gene editing may be used one day to create “designer babies” and forever alter the human genome.
Experts from around the globe are gathered in Washington, D.C., this week to discuss the clinical potential and ethical pitfalls of human gene editing. The three-day international summit, convened by the U.S...
