Gene editing and eugenics

A study published last week in the journal Cell has led to speculation that a powerful new gene editing technique is about to be developed.

Gene editing has received widespread media coverage over the past few months. Most of the excitement has centred on a specific gene editing technique, the CRISPR-cas9 system. Research conducted with CRISPR-cas9 on human embryos has been highly controversial, at least partly because some people fear it will lead to gene editing being used to alter the human germline for clinical applications, and will have unpredictable effects on future generations.

Knowing is half the battle: preconception screening

In a recently released report the UK Human Genetics Commission said there are “no specific social, ethical or legal principles” against preconception screening. If a couple may benefit from it, testing should be available so they can make informed choices. Information about this kind of testing should also be made widely available in the health system (and in school). The responses in the news have been along predictable lines, with critics warning that this is a modern version of eugenics or that it would lead to some people being stigmatized.

Nazi Eugenics Returns to Germany: The Paradox of Eugenics

The prestigious scientific journal, Nature, reports that Germans are poised to allow genetic testing of embryos for serious genetic disorders. This follows a recent judicial judgement that genetic testing of embryos for serious disorders did not fall under German laws that ban destruction of embryos. Now,

The Leopoldina, Germany’s national academy of sciences, has published a report strongly recommending that preimplantation genetic diagnosis of early embryos be allowed by law when couples know they carry genes that could cause a serious incurable disease if passed on to their children.
