Despite CRISPR Baby Controversy, Harvard University Will Begin Gene-Editing Sperm (technologyreview.com) 167

Even as a furious debate broke out in China over gene-edited babies, some scientists in the US are also hoping to improve tomorrow's children. From a report: [...] Amid the condemnation, though, it was easy to lose track of what the key experts were saying. Technology to alter heredity is for real. It is improving very quickly, it has features that will make it safe, and much wider exploratory use to create children could be justified soon. That was the message delivered at a gene-editing summit in Hong Kong on Wednesday, by Harvard Medical School dean George Daley, just ahead of He's own dramatic appearance on the stage (see video starting at 1:15:30).

Astounding some listeners, the Harvard doctor and stem-cell researcher didn't condemn He but instead characterized the Chinese actions as a wrong turn on the right path (see video). "The fact that it is possible that the first instance of human germ-line editing came forward as a misstep should in no way lead us to stick our heads in the sand," Daley said. "It's time to ... start outlining what an actual pathway for clinical translation would be."

      Growing up with someone who, is now recently deceased, who would have benefitted from this, I absolutely am adamantly opposed to 90% of the arguments i hear about "ethics". Most of them are disingenuous efforts by people who want to keep the technology under wraps, practiced only in secret back rooms available to the rich. Many more are religious fruitcakes and their ideas about their chosen gods will, he's not my god, I'm not interested in his opinion.

      However, there are reasonable concerns about first, yes I have something that will cure say, cystic fibrosis, but it also may cause cancer @40, or a few dozen other very unpleasant side-effects. And while *I* may find it acceptable, will the life that I create agree with my decision 40 years hence. That's a valid concern, but I don't know of any way of resolving it, but by doing it, seeing the fallout and either refining it or removing it as a legal technique. We don't actually know what we don't know, and we shouldn't let us stop it.

      Then there's a concern about what happens to our survivability if the entire population is running around with edits to their genes, and whether we can continue to live without it. Is it our heroin? It should be a concern. I am not sure it should stop us, but we should consider how we want to approach availability and legality of some of the more superficial edits (i.e. every man wants to be blond haired, blue eyed an wielding a 12" wang, the latter of which may actually be problematic to our long term survival, particularly if edits cause him to be infertile 75% of the time).

      I know we have all this ethics crap, but if we eliminate something like Cystic Fibrosis, I don't see a downside here.

      Many of the inheritable diseases we see are there because the genes don't just control one thing, but several. Often, a genetic variation does not only cause a negative, but is accompanied by something beneficial. Evolution has had a long time to weigh the advantages against the disadvantages. If it were only disadvantages, they would generally have been eradicated from the gene pool.
      The most famous example is sickle cell anemia, which protects against malaria for those who only have the gene from one parent.
      And some HLA antigens give strong resistance to influenza A, at the cost of an increased risk of rheumatic diseases. What would you pick?

      In the case of Cystic Fibrosis, it's an an autosomal recessive disease, meaning that 25% of children of two healthy carriers get CF. That it is present in the gene pool indicates that there may be an heterozygote advantage to being a carrier with the mutation on only one gene. Eradicating the genetic variation that causes CF would eradicate that benefit too, whatever it may be.
      As for the benefit to individual couples, CRISPR doesn't add any benefit that isn't already there today. Prospective parents who both are carriers can test the embryo and terminate pregnancies where both genes are added.

      It's not quite that simple.

      To use CRISPR on the gene line you really want to be doing your modification as early as possible. So right away, you're talking about in vitro fertilization. The question is, if you're interested in preventing something like cystic fibrosis, wouldn't it be easier and simpler to just screen those cells before implanting them?

      Now, most genetic diseases, and other traits, are way more complicated than CF. They're not just a binary one gene you've got it or you don't. Usually it's not even a few genes, it's a lot of them. So if you want to influence those, maybe you want something a bit stronger than just screening. But then you have all the practical problems with unintended consequences, because you don't actually know exactly what you're doing, you're just tweaking some things to nudge the baby in a particular direction.

      The Chinese case is kind of an interesting in between. It's a single gene edit to confer HIV resistance, but it's presumably not an allele that either parent had already so there's no way you could achieve it through screening embryos. However, even CCR5-d32 isn't all gain like fixing the CF gene would be. Having the allele does confer resistance to some strains of HIV, but it also knocks out a bit of the immune system. There's some evidence that it decreases resistance to influenza, for example.

    • the worry is that they don't completely understand everything they're modifying.
      For example, sickle cell anemia grants increased malaria resistance to those who carry it repressively.
      The worry is that you change a gene to remove problem X, and accidentally introduce problem Y. Which may not be immediately apparent.

      More like "there are beneficial uses of this technology, so we should follow through on those". A better analogy is we didn't stop pursuing nuclear power because it could also be used as a weapon. There's definitely morally and ethically troubling issues, like controlling gender. There's also non-troubling things, like removing genetic disorders. The possibility for the first shouldn't preclude using it for the second.

If they don't want that, odds are they won't accept a genetic fix to prevent the problem from developing in the first place.

          That's an individual decision, and it's up to the parents. If they don't want to consider a genetic fix because they don't consider it a problem, that's fine, but it shouldn't stop the research from helping others who do want to correct the issue in their children.

          I personally see the decision to not add a genetic fix as more ethically ambiguous than the research for a fix. You could remove one stumbling block from your child's life and chose not to. That said, if you're confident you can look your adult child in the eye and explain your reasoning with conviction if they ever come asking you chose not to, then, again, it's your choice. All you can do as a parent is make the choices you think are right.

          Suppose for sake of argument that sexual preference has a genetic control (I don't believe that this is the case, but this is for the sake of argument) and some parent doesn't want (or does, as some people today may well do) their child to be a homosexual. Is that something that's permissible to "fix"?

          I give the same answer here as the rumored answer to why Jean-Luc Picard is bald in the 24th century: surely they have come up with a cure by then. The answer is, "by the 24th century, nobody will care."

          Ideally that's just not something parents will care to change. If they do care, it's probably better for the child to go ahead and make the change, instead of setting them up to grow up homosexual in a family that is non-accepting, and all the psychological issues that would come with that.

          This is not a popular opinion, but I think the whole debate around “fixing” homosexuality would be very different if (a.) there wasn’t a very bad historical precedent and (b.) there actually was a way to do so.

        Except that that is troubling. Many genetic inheritable diseases are recessive, and being a heterozygote carrier gives benefits, while the disease from inheriting the gene from both parents is highly detrimental. If eradicating the disease, you also eradicate the heterozygote benefits.

      The part about fixing things like Huntington's and such isn't a moral debate. If we can, we should. Eliminating genetic disorders is to our general benefit. I'm worried about taking it too far. For example, I'm ADD (quite seriously so). Medications are not helpful to me because of side effects. However, in some ways it's a superpower. I have a knack for spotting the holes in plans at work because I draw on all of the odd things I picked up because of random curiosities. I can get multiple specialists involved because I draw on their various backgrounds, which means I get teams to talk to each other. Is it really a disorder?

      Sort of, because it sometimes gets in my way. But if we edit to the point our minds form with less variation to avoid "disorders" we may be damaging our potential. My inability to mentally stand still has made me an odd success, but it took a long time to find a good niche for myself. Our society is bad at managing differences well, which is a shame. In tribal days, those differences allowed specialization which allowed the tribe to grow. Our society still needs these differences to thrive.

      I don't think editing eye color is really a moral issue. Skin color might be because of society's racial issues, however. We're going to be running up against some tough questions very soon.

        There are much easier ways to avoid Huntington's, cystic fibrosis, or other single gene disorders. Screen the embryos. You need to do IVF and screen embryos for CRISPR anyway.

This is a discovered thing, not an invented one. It can also cut and paste, which is how it can be used to remove known bad genes with good copies. This is also why it has been used in research to combat latent HIV infections.

            I'm talking about discarding embryos, specifically blastocysts. This is done every day. It's an unavoidable part of IVF, and also an unavoidable part of a reasonable reproductive gene editing procedure.

            • Well, you would want to check if it took before you used the sperm, ideally. But with most genetic diseases, you need to both cut AND paste, meaning you need CRISPR for any editing you want to do where a bad gene is replaced with a functional one. This gets complicated, but extra genes are relatively rare in genetic disorders from what I've read. It's usually genes where a bad codon is in place, so an incorrect amino acid is used to generate the protein. Usually, you still get a protein, but it's ill-suited
