Introduction

In October 2018, the world's first genetically edited babies were born, twin girls given the pseudonyms Lulu and Nana; Chinese scientist He Jiankui used CRISPR technology to edit the CCR5 gene in human embryos with the aim of conferring resistance to HIV. In response to the international furor, China began redrafting its civil code to include regulations that would hold scientists accountable for any adverse outcomes that occur as the result of genetic manipulation in human populations. Now, reproductive biologists at Weill Cornell Medicine in New York City are conducting their own experiment designed to target BRCA2, a gene associated with breast cancer, in sperm cells. While sometimes considered controversial, gene editing has been used as a last resort to cure some diseases. For example, a precursor of CRISPR was successfully used to cure leukemia in two young girls when all other treatment options had failed. Due to its convenience and efficiency, CRISPR offers the potential to fight cancer on an unprecedented level and tackle previously incurable genetic diseases. However, before we start reinventing ourselves and mapping out our genetic futures, maybe we should take a moment to reevaluate the risks and repercussions of gene editing and rethink our goals and motives.
