Human Genetic Enhancement Might Soon Be Possible – But Where Do We Draw the Line?

How far will we allow genetic enhancement to go?

The first genetically edited children were born in China in late 2018. Twins Lulu and Nana had a particular gene – known as CCR5 – modified during embryonic development. The aim was to make them (and their descendants) resistant to HIV. By some definitions, this would be an example of human enhancement.

Although there is still a long way to go before the technology is safe, this example has shown it’s possible to edit genes that will continue being inherited by genetic offspring for generations. However, we don’t yet know what effect these genetic changes will have on the overall health of the twins throughout life. Potential unintended changes to other genes is a grave concern which is limiting our use of gene editing technology at the moment – but this limit won’t always be present. Continue reading

How Should We Regulate Genetic Enhancement Technologies?

A Guest Post Written by Jonny Anomaly

 

It’s been 20 years since Allen Buchanan and his colleagues published From Chance to Choice: Genetics and Justice. The book was a landmark, and it repays careful reading.

But there is at least one kind of question that has been largely (if not entirely) ignored in discussions about whether we should regulate parental choice, once parents have access to technologies that allow them to sculpt the genetic endowment of their children. How should we think about reproductive choices that are good for each but not for all? What should we do when there is a conflict between parents selecting the best traits for their children, when a different distribution of traits might be better from a social standpoint? Another way of asking the question is this: how should we think about situations in which there is a potential conflict between the principle of procreative beneficence and the principle of procreative altruism?
