The promise of genetic technologies is undeniable, but so are the pitfalls. In this article, we explore the potential of at-home genetic tests and polygenic embryo selection, while also addressing the ethical concerns and limitations. 'Some of them have accuracy that's close to zero', say experts. But here's where it gets controversial... Are these technologies really as powerful as their marketing claims? And what impact could they have on society if used irresponsibly? We delve into the science behind these technologies, the myths surrounding genes, and the potential for both good and harm. 'We're pretty early on in this 'post-genomic' era', explains Sam Trejo. While our ability to predict traits based on a person's genome is growing, there are still lingering questions about the extent to which we should use research technologies in the wider world. Nicoletta Lanese interviews Daphne Martschenko and Sam Trejo, who discuss the limitations of direct-to-consumer genetic tests and polygenic embryo selection, as well as the potential for application genetic screening. They also address the myths about genes and misconceptions around the influence of 'nature versus nurture'. 'We didn't have to agree on everything in order to agree about the need for regulation of these technologies', say the authors. This article is for informational purposes only and is not meant to offer medical advice. It is a call to action for policymakers, researchers, and the public to engage in a conversation about the regulation of these technologies and the need for greater transparency and understanding.
