Doctors in the US have become the first to treat a baby with a customised gene-editing therapy after diagnosing the child with a severe genetic disorder that kills about half of those affected in early infancy.

KJ was born with severe CPS1 deficiency, a condition that affects only one in 1.3 million people. Those affected lack a liver enzyme that converts ammonia, from the natural breakdown of proteins in the body, into urea so it can be excreted in urine. This causes a build-up of ammonia that can damage the liver and other organs, such as the brain.

Writing in the New England Journal of Medicine, the doctors described the painstaking process of identifying the specific mutations behind KJ’s disorder, designing a gene-editing therapy to correct them, and testing the treatment and fatty nanoparticles needed to carry it into the liver. The therapy uses a powerful procedure called base editing which can rewrite the DNA code one letter at a time.

      Yeah I don’t see how this won’t happen now. As soon as parents are given the option to prevent systemic genetic diseases like congenital blindness, the next question will be, “do you want them to be a bit smarter?” Very few parents are going to say no.

        The problem is intelligence doesn’t automatically mean better life, especially not in a country like the US.

          Well, if the parents are affluent enough to pay for a non-curative genetic editing I’d say that’ll help.

          It is the single greatest correlate for life outcomes. Higher income, longer lifespan, lower addiction, higher employment, higher wealth, lower crime, better physical health on every metric, and lower rates of fatherlessness. These effects all compound the next generation too. There is nothing else in sociology which comes even close to IQ in predicting life outcomes. Not income, race, location, education, or fatherlessness.

          Of course nothing guarantees a “better” life.

            Well that’s just bullshit and I looked it up to be sure it was.

            Income is the best life outcome. I did find that high IQ is more correlated with depression and suicide however.

        Based on what? The US discussing legalising genetic experimentation for military uses is the pathway to Gattaca.

        Not saying you’re wrong, curious about your time-line

          Just a general timeline for technology to become ubiquitous. Starts small, for the rich or “for nerds”; begins to take over, now seen as “normal”; eventually you’re the weird one for not having it.

          Microwave ovens & the Internet are the two I can think of in my lifetime, I’d say an average of about 20 years for the cycle to complete, so about a generation.

      A baby (and more people after) not dying is an afterthought to you, you are mostly concerned with a fucking SciFi flick not coming true somehow.

      Grow up, seriously.

      This tech will save and improve a lot of peoples’ lives. It will be also be used frivolously by the rich to ‘improve’ (or actually fuck up) themselves just like they use current medical tech. Meanwhile some poorer people that need it to survive will be denied it.

      These are political issues, long existing, not problems with this medical development.

        I would suggest they’re more in touch with the science. It haunts science, we know we must do it for the benefit of humanity, but with the knowledge - the powerful and capital will use it for themselves.

          How so?

          It haunts science, we know we must do it for the benefit of humanity, but with the knowledge - the powerful and capital will use it for themselves.

          The solution is not halting technological advancement(especially medical technology) but to try and change our political systems.

      You know what? You’re right. Let’s cancel medicine because it is eugenics. Let nature take care of those who are too weak to live. Fuck em.

      Fuck vaccines, fuck lifesaving surgery, fick meds, fuck gene-editing that can save a baby from a life of suffering due to severe genetic disorders.

      Fuck them all. We wouldn’t want to change anything for anyone because that might make some ignorant Karen think that medicine is eugenics.
