In the case of flaviogene (or whatever it is called) it might be that the editing didn't get put in the right spot, as they can't do that with this method. In the case of CRISPR, it might be that the edited cells are rejected and the faulty DNA takes over. Either way, no treatment is 100% guaranteed to work for everyone, even gene editing at this point.

Getting a virus to infect the cells that are problematic isn't always easy. As you can see in this case, both treatments, require a bone marrow transplant to work. That isn't tenable for most humans. The treatment for my skin disease, a viral vector treatment, the first topical ever approved, works only on open wounds. I didn't get treatment this week, because all of my wounds are slightly healed and it wouldn't do any good. They're hoping to be able to develop more, because one of the conditions that they really want to treat is wrinkles. The problem is getting the skin infected, when the epidermis is extremely effective at stopping the herpes virus.

Its weird listening to you talk about things related to stuff ive worked on and with in the past.

Even though the process is precise, there is always the chance of it not going to the right target sequence such as cutting too early or cutting or late or even in the whole wrong area and causing unexpected mutations to protein encoding and such. Getting the results back the biggest statisic I would want to see is the ratio of On/Unaltered/Off targeted that occured. It seems their method must have been reliable enough due to most patients feeling well after treatment but I still worry for them due to the as stated blood cancer potential.

Chemo/stem cell transplant part isnt as bad as it may sound for most, I didnt have any adjustments to my stem cells but I went through the filter/chemo process to treat lymphoma cancer. Not going overly into detail to keep it shorter, the collection of stem cells takes anywhere from one to several 5 hour hospital visits, for the vast majority its 1 or two days and you go home immediately after they are done. The chemotherapy requires a significantly longer hospital visit, but thats because you lose your immune system and by staying at the hospital you can isolate yourself. Assuming you dont catch anything the other main side effect is fatigue, you will have very little energy immediately after and some fatigue/weaker immune system issues for several months afterwards, but not so bad you cant be at home.

[@MachFiveFalcon]

Incredible news! I'm amazed at how low risk it is from a layman's perspective. As far as the issue is with the benefits not carrying over to eggs and sperm, widely accessible prenatal DNA testing like in Iceland could help parents ensure their baby doesn't have Sickle Cell or other genetic disorders.

[@brianchew2565]

The therapy not affecting eggs and sperm is a feature, not a bug in this instance. Modification of gametes (egg and sperm) is hotly debated ethical issue. The general consensus is that the risk of off target modification (like where he mentioned DNA incorporating anywhere in the genome and potentially breaking something) is regarded as still too high with crispr. Essentially, the risk to a potential person who cannot consent to that risk is just too high for gamete modification. Beyond that, the fears that such a modification will open up the door to designer babies is something that is discussed frequently. While it is extremely rare to find people who would support this, changing regulation of gene therapies to allow changes that can be passed to offspring will, as he said, open the floodgates, and not all of the people who take advantage of that will be looking to just change genes to cure future babies. Your point about preimplantation/prenatal genetic diagnosis(or preimplantation genetic testing) (PGD or PGT) is hugely important. There are still ethical concerns that genetic counselors have to account for, such as people wanting to implant only children of a certain sex or with certain desirable traits, but the potential for PGD to massively reduce the risk of passing on genetic disorders to ones children can have huge benefits. This is especially true as, for many disorders, parents are not guaranteed to pass on a disease to their children. Again, there is a lot of sensitive discussions that have to be had about what traits are okay to select for against, and how do we as a society treat these genetic disorders in such a way that we do not devalue the people who have already been born who have those traits. I am still hopeful such technology can help us achieve a healthier happier future for our children.

[@Rwdphotos]

Well I’m sure there’s still a decent amount of risk, considering the chemo therapy would wreck havoc on the immune system for a while, as well as impact organs if not enough new blood cells are able to be made by the body. They would likely need to be infused with blood during the entire process and be immunocompromised, so any infection would be an incredibly serious event.

[@H2Dwoat]

Hi, it’s a shame that it’s likely to be so expensive in the U.S. and hence likely to be unfeasible for the majority. Similarly here in the UK NICE decides if the NHS will be able to offer expensive treatments. I’m not sure what the answer to this is but hearing of exciting new treatments for some awful diseases is always tempered by the reality of cost smacking me in the face. Hopefully I am wrong and it is affordable for everyone.

[@edwardallenthree]

My insurance company was more excited than I was to cover my $25k a week genetic treatment. I have theories as to why, but, what it comes down to, is in both the UK and the United States it is not the rare diseases which are causing our health systems to be financially insolvent.

[@brianchew2565]

In this case, its a result of the actual cost of development. Developing a therapeutic like this already has massive costs to a company, that they would like to recoup from patients so they further develop new therapies, but the technology to carry out this therapy is also very expensive, and the cost to maintain the standards for a lab to do this and ensure the therapy is safe for a patient is also hugely expensive. At the moment, that means that most gene therapies or stem cell therapies will be wildly expensive. This leads to a lot of discussion among researchers about what therapies are best to pursue, as we want to help as many people impacted by diseases or disorders as we can, but further development of this technology also has a high likelihood of decreasing the cost of future therapies. All of this is to say that is sucks that this is so expensive at the moment, but there is great hope that costs will decrease in the future, and scientists who develop these (at least within public sector research) are actively looking at ways to make these more widely available all the time.

[@raerohan4241]

Searching for affordable alternatives is a big part of science research in general. It's expensive right now, but going by past experience, that will definitely change in the future. E.g. the cost of sequencing a genome nowadays is a drop in the bucket compared to how mind-numbingly expensive it used to be at the advent of that technology

Family member had a blood disorder and had to get a bone marrow transplant. This seems effectively the same process but instead of a donor donating stem cells, the patient's own stem cells are used. This is good though for not having to worry about rejection. GVHD & chemo were the worse parts. This removes one from the equation.

[@rheinbewachen1211]

I desperately hope the cost changes soon. A cure for chronic disease like this is miraculous... but if that cure can be withheld so easily, the shadow of eugenics always looms.

Many years ago we had a young African-American male come into the hospital in respiratory crisis form a Colorado mountain town.

The recovery hospital was at an altitude of over 6000 feet and he was stabilized there. Once he was well enough to leave he was told he could NOT go get his car and that he needed to take a VERY long way home avoiding all mountain passes. I've often wondered how he was doing.

With regards to sickle cell. It appears to be concentrated in Certain parts of Sub-Saharan Africa. With Malaria being an issue, this would make sense. either the Malaria gets you, or the Anemia.

[@billybob7688453]

The fact that Heterozygotes of the sickle cell disease persist to this day show that it was slightly selected for in terms of population genetics. Those who could resist malaria survived and were able to pass on their genes. This explains why we see it more in these populations, but having both copies of the gene is still detrimental no matter the lifestyle. Without access to treatment, I'm sure having sickle cell is life threatening, it's just a matter of time.
