Torah Kachur, PhD, lecturer at the University of Alberta and science journalist, in a Feb. 15, 2018 article, "Enhancing Athletic Performance on a Genetic Level," available at, stated:

“If CRISPR/Cas9 genome modification is ever found to be doable and safe in humans there is almost no way to ever catch a cheat. You’d have to get a sample of their DNA before they even become competitive athletes, when they are kids, to have some reference sample so you can tell if any changes have been made in adulthood.

I’m presuming no one would irreversibly change the genetics of a child before they even show athletic potential and I hope that is safe to assume.

The thing is that doping technology has always stayed one step ahead of detection, but it has only stayed one step ahead. So if CRISPR/Cas9 modification of the genome in humans becomes possible and is done by athletes, we can only hope the minds at WADA are just years or even months away from catching the cheaters. Now with retroactive punishments it’s still possible to catch a cheat even if it takes a while to catch up.”
