What’s the difference between a cure, a therapy with persistent impacts, and ‘playing god’? Human germline modification could also theoretically allow for the installation of genes to confer protection against infections, Alzheimer’s, and even aging. Editing a single SNP is shockingly easy; it would be completely feasible for an ordinary fertility clinic to do so (maybe not literally right now, but it will be soon.) There are several concepts I think might have been intended, and this statement possibly conflates them. If a single optimal genome exists, shouldn’t every person be able to have it? To even attempt to answer something like this is hugely speculative and probably a waste of time. After several implant attempts, successful pregnancy was achieved. Two particular gene markers, HLA-DQ2 and HLA-DQ8, are observed in the vast majority of celiac disease cases. But I don’t think democracy is a good example of such a case. Was that a bad thing? – as discussed (briefly) by the authors, the possibility of human germline modification for enhancement Of course, this newfound power raises several ethical concerns. A discussion on human genome editing would not be complete without evaluating the potential to create “designer babies,” a term commonly used in the vernacular to refer to babies with genetic enhancements. It doesn’t matter what ethical arguments are made against designer babies. [ACC] Should Gene Editing Technologies Be Used In Humans? Generally, the more common something is, the less valuable it seems. Other times I cringed at analogies that brought more confusion than illumination to the idea they were trying to get across. This collaboration tackles an important topic, which makes it disappointing to see how thoroughly it fails to reach any meaningful conclusion. With a technology so potentially life-changing, the burden of proof should be on those who claim it will be used beneficially and responsibly if adopted. If a mistake is made in the process and a new disease inadvertently introduced, these changes will persist for generations to come. I think if the technology itself is safe, reducing mutational load would be pretty safe. My point was to push back on what I think the ACC submission effectively claimed: ‘genetic mutations are only one way cancer arises, while epigenetic mutations are another possible route’. Jennifer Doudna offers the following visual: “Imagine trying to correct an error in a news article after the newspapers have been printed and delivered, as opposed to when the article is still just a text file on the editor’s computer.” Germline editing may therefore provide a more expedient option for the prevention of some genetic diseases such as sickle cell disease or cystic fibrosis. And once that happens, assuming the designer baby thing works, you get the children of the most ambitious people with money in the US having the designer kids who turn out to be, on average, smarter, taller, better-looking, harder-working, and more ambitious than everyone else. The only anti-egalitarian force I can think of is that of the bioethicists who tend to make vain and apathetic statements about the technology in an attempt to arbitrarily stigmatize and ultimately outlaw it. I know that’s putting words in their mouths, but I think it’s justified otherwise why include it in the discussion? (Maybe those people will have enhanced resistance to the next major pandemic.). 84 thoughts on “ [ACC] Should Gene Editing Technologies Be Used In Humans? I would also mention prime editing (published October 2019 here: https://www.nature.com/articles/s41586-019-1711-4). People will generally want to make their children successful in their current environment, and will do so if they can. Note that there have been many cases where initial research showed significant impact of treatment (in effect size or for the scientific definition of significant), that more research showed to be false. Is it really that easy from a technical standpoint? I think it is a little more bidirectional than that. If a more efficacious means of doing this comes along why shouldn’t the government also want to spend hundreds of thousands of dollars per child effecting it? This is a great point. More specifically, we also performed genetic analysis to see if the CRISPR-Cas9 system made DNA breaks at places that it’s not supposed to, and we see no evidence of that.”. But if e.g. You did some searching and have found this same virus has been endemic in human populations for over five hundred years, we just didn’t know until now that many people we thought just had weak immune systems were actually infected by this virus. That’s where the technology is headed in the near future, and I don’t think most people object to that kind of treatment. Designer babies become possible, but they’re very expensive. All Rights Reserved. “Even if we do make the changes we want to make, there’s still question about whether it will do what we want and not do things we don’t want.”, Nevertheless, a slight increase in cancer risk might be a worthwhile trade-off for many patients with genetic diseases, such as the aforementioned SCIDs, which affect 1 in 50,000 people globally. Imagine you have an unedited kid, running around doing all the crazy things unedited kids do. However, designing these enzymes requires extensive work, making the process costly and time-consuming. They make it sound like cancer is driven by a bunch of hypomethylation, but much of those epigenetic changes are driven by the epithelial to mesenchymal transition characteristic of many cancers. Thus, we would expect that there are genetic abnormalities that are required to maintain the tumor phenotype, and that fixing those genetic abnormalities would likely stop tumor growth – regardless of the epigenetic changes present in tumor cells. In these cases I was left wondering how much they really understand the subject, or whether they’re relying on others to frame the conceptual landscape for them. Whether our efforts will alleviate human suffering or ensure the survival of our species, only time will tell. (Although we have other ways of producing offspring that are genetically similar, like with the use of surrogates.) We have eliminated one of the most terrible plagues that used to kill us off, and are working on others, and we’ve found a way to prevent nearly all our kids from getting the childhood diseases that previously carried a certain number of them off every year. There needs to be other genetic problems as well, I just wanted to push back a little against this line: when it’s most likely genetic changes that are creating that microenvironment. 1. But I think you go too far towards the genetic direction and away from microenvironment. When only the father is HIV-positive, as in this case, sperm washing alone is usually sufficient to reduce transmission of the virus. In other words, genes that promote tumor formation are turned on while genes that suppress tumor formation are turned off. Indeed, why worry about a potentially pathogenic gene if it is never expressed? I think in many ways controversial philosophical questions are not very analogous to difficult empirical ones…, This doesn’t really relate so much to the post as opposed to the subject in general (except insofar as I think it’s relevant that the post didn’t mention this), but, to repeat what I said on an earlier thread…, The possibility that scares me isn’t people using gene editing to enhance their children — I mean, greater capabilities are a good thing — but to make their children more things-their-parents-want-but-that-are-not-in-fact-better. Then let the weirdness begin! As previously mentioned, the first genetically edited babies were born in October 2018 after Chinese scientist Dr. That endorsement of the status quo will just result in adoption snowballing, possibly out of control. Social media is killing book reading habit! This is relevant for tumorigenesis as damage, over-activation of cytokines in inflammatory diseases, etc, can likely help tilt the balance towards malignancy by pushing more towards a mesenchymal phenotype. CRISPR is currently being used in clinical trials for cancers and blood disorders; since these interventions won’t lead to heritable DNA changes, these trials don’t face the same ethical dilemmas as Dr. He’s experiment but may nevertheless carry risks. If you change a variant that occurs in 0.1% of the population into a variant that occurs in 90% you are not going to break anything. How would this be different from gene editing, where you’re changing the representation of specific (presumably maladaptive) sequences in future generations? In 2017, two infants with relapsing leukemia were successfully treated with these “off-the-shelf” CAR T cells, which were modified using the genome editing tool TALEN. The distinguishing feature of gene editing is just how major and just how long-term those issues can be. Because those epigenetic changes are driven by pre-existing genetic ‘programming’ that was already present and got activated inappropriately and lead to cancer. We may get very non-optimal outcomes, especially if people overshoot the optimum. That makes it cheaper still. That was asking about toddlers. Also agree with the implied logistical difficulties. A patient must have a sufficient number of immune cells prior to beginning therapy, which may not be the case for patients who have already received chemotherapy. Discussions of heritable enhancements in particular raise fears of a possible return to eugenics. Chinese authorities suspended all of He’s research activities, saying his work was “extremely abominable in nature” and a violation of Chinese law. It’s hard to talk dispassionately about it — and that applies to “germline” human editing. Me: We totally can’t do Brave New World yet because CRISPR only does one gene at a time. With a technology so potentially life-changing, the burden of proof should be on those who claim it will be used beneficially and responsibly if adopted. Sorry, what is the argument? CRISPR technology holds invaluable potential as a research tool and possible treatment for diseases caused by single-point genetic mutations. Human generations are long; human lifespans are longer. And for heavens sake, start with fixing serious (= lethal) problems that are well understood, and essentially entirely genetic, before trying to fix more complex issues – and all this before trying to “improve” perfectly functional people. However, I don’t see why you could make a moral distinction between making children more obedient and agreeable by transfering your culture and relegion to them, versus making them more obedient and agreeable by gene editing. 2. Almost certainly one of the largest factors in cost/benefit analysis will be the extent to which starting now will speed up the development of more powerful and accurate techniques. Furthermore, genes that encode for physical traits may also impart increased vulnerability to certain diseases. That’s what scares me, not some idea that selecting for actual enhancements will somehow backfire…, (I think I likely picked up this argument from someone else, but if so, I forget who, sorry…). Incidentally, this probably means that in the medium run, genetic editing will be egalitarian in outcomes. What scares me more is the possibility that the state, not the parents, would do this, making it mandatory. East Asian infants and kids are famously better behaved. Genome-wide association studies, or GWAS, began examining population data over time to look for possible associations between genetic variants, or genotypes, and physical traits and diseases, or phenotypes. When the first effective anesthetics allowed surgery to become much more commonplace people talked about the the human body as sacrosanct, and complained surgeons were ‘playing God’. Yeah, the term ‘playing God’ has been used for a long time in relation to new medical advances. ... a comparison between the traditional inheritance and development of a genotype and the cellular manipulation of a genetic trait through gene editing. If I were dictator, I’d put off all but the most cautious gene editing until bioengineering advanced to the point where errors could be undone. I feel like this entry, moreso than the others thus far, has suffered from a degree of blatant “one author writes one paragraph, the next author writes the next paragraph, et cetera”. Some diseases, like sickle cell anaemia, Huntington’s disease, and severe combined immunodeficiency, are predominantly genetic, while others, like cardiovascular disease, malaria, or obesity, are predominantly environmental. Whether it’s even possible to use it against complex multigenic diseases we’re still struggling to understand is not clear. Nevertheless, sickle cell disease has become prevalent in countries currently unaffected by malaria. All those might look like playing God to someone from a couple hundred years ago, but I sure don’t plan to turn them down if/when I need them. Somehow mIx embryonic stems cells with some placental stem cells and you could theoretically build an engineered human from serially-modiified ESCs. There’s a very dark utilitarian perspective of medicine that sees treating disease as a way of perpetuating maladaptive genes within the population. Categories: APA (edition "APA 6") Health Care and Life Sciences. One novel I recall had “control naturals”, complete with an allowance large enough to live on. Counterweight: It’s probably easier in a technical sense to raise below-average traits to the average than it is to enhance average traits to superhuman levels, and CRISPR has made genetic engineering “cheap” in a certain sense (though I’m sure the total cost of a treatment intended for a human would still be high for a variety of reasons.). 3. “Nevertheless, despite recent medical advances, cancer treatment has not seen significant improvement in decades.”, This is simply incorrect. I think that if we find the genetic correlates to “desires to contribute to the care of retired parents,” that will give many people a strong incentive to select their kids’ genes. You also have trust problems, even if it is easy to edit genes it is easier to do nothing and say you have edited the genes, and I can’t see a practical verification mechanism that doesn’t require trust. EMT can be triggered by genetic changes, but also very much by the environment, even in a genetically normal cell. Germline editing may therefore provide a more expedient option for the prevention of some genetic diseases such as sickle cell disease or cystic fibrosis. (Not a literal peacock tail, of course; but e.g. While we’re worrying, I suspect hypomania will be one of the desired traits, and that would be easy to get wrong. However, since the pathological mutation for sickle cell disease has already been clearly identified, correction of the mutated gene using CRISPR may offer a more straightforward approach. This was mentioned briefly in the essay, but I think I’m not sure the nuance is clear to an audience that doesn’t have a strong biology/immunology background. I agree. I’d think the de novo creation of life from non-living materials would fit. Moreover, while gene expression and the tumor microenvironment are viable targets for cancer treatment, gene editing can be considered a last resort therapy for certain cases in which other interventions have failed. 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. Next, eggs were fertilized by sperm to create embryos, on which Dr. It then moves to survey proposals that have been advanced to construct mechanisms of governance for overseeing research with genome editing in humans. On the other hand, gene therapy trials using viral vectors were recently halted when 25-50 percent of gene therapy patients developed leukemia resulting from the insertion of a gene-carrying virus near an oncogene; a gene with the potential to cause cancer. The cost to Control Natures is that they can’t win at much of anything, though there one person in the small group that’s running things who’s a Control Natural. Complexity of effects of genes on people is already something current methods can handle. How often does disease arise as the result of genetic mutation alone? Making these types of edits successfully would therefore require inhibition of P53; however, cells could become more vulnerable to tumorigenic mutations and the development of cancer as a result. Stanford scientist Dr. Matthew Porteus demonstrated the efficiency of this technique and said in an interview, “We don’t see any abnormalities in the mice that received the treatment. Today’s Saturday Morning Breakfast Cereal (SMBC) strip raises that exact point: “http://www.smbc-comics.com/comic/selection”. Cancers are front and center among the conditions gene editing therapies are targeted to treat. Almost all types of human tumors are characterized by two distinct phenomena: global hypomethylation, which may result in the expression of normally suppressed oncogenes, genes that promote tumor formation, as well as regional hypermethylation near tumor suppressor genes. 2a. Nevertheless, many consider mainstream germline gene editing an inevitability. A study conducted by the Wellcome Trust Sanger Institute in Cambridge, England analyzed DNA sequencing data from 179 people of African, European, or East Asian origin as part of the 1000 Genomes Pilot Project and discovered that healthy individuals carried an average of 400 mutations in their genes, including around 100 loss-of-function variants that result in the complete inactivation of about 20 genes that encode for proteins. Gene editing and manipulation is a newer, but rapidly growing field. The most oft-cited example discrediting this theory is that of giraffes elongating their necks by stretching to reach the treetops and then passing on this trait of long necks to their progeny. Perhaps the centrality of the gene in driving human health has been overstated. 1. In other words, the same oncogenic mutation that is adaptive for cancer in altered tissue is not advantageous to cancer in healthy, homeostatic cells. I guess somewhere there is going to be a statistic that the same percentage of people is dying of cancer as 30 years ago, which ignores the fact that people have to die of something and simultaneous advances in different disease areas will tend to keep the death stats balanced. Ethical & Social topics for Group Discussion, Creative & Abstract Topics for Group Discussion, General Interest Topics for Group Discussion. Please forgive my insufferable urge to play copy editor. I think that’s why issues around fertility, childbirth, and abortion are so fraught: because they touch on something very primal, almost sacred. Fair question. Or that currently neutral mutation that’s going to save a fraction of the species when some future environmental challenge occurs. 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. The concept of genetic determinism purports that our genes are our destiny, but genes are not nearly as important as gene expression. Even that’s not enough. But think of the possibilities! As indicated earlier, Dr. He’s efforts to confer resistance to HIV may have also resulted in increased susceptibility to infection by West Nile virus or influenza. If the technology becomes stigmatized and outlawed then it probably would be the case that only rich people with millions of dollars able to fly to Brazil would be able to afford it. Is there a line when you’ve crossed too far, flown too close to the sun? Personally I expect: The idea of a more agreeable, obedient humanity strikes me as not only horrifying but as maybe even an existential risk, not in the sense of something that could lead to extinction but in the sense of something that could permanently curtail human potential. In general I think relying on our instincts in an environment (such as one in which we have access to powerful gene-editing tools) very different from our environment of evolutionary adaptation can lead to major issues.
