In a recent article published in Nature, scientists have revealed the limitations of gene technology when it comes to improving human health. In particular, the authors observed that current gene editing technologies such as CRISPR-Cas9 are limited in their ability to target long stretches of DNA, making it difficult to target multiple genes or genes that are spaced far apart. Furthermore, editing of large, complex regions of the genome can lead to unexpected side-effects. The authors conclude that while gene editing has the potential to improve human health, this potential is limited and a better understanding of the underlying biology is needed.
