This is absolutely world changing. I've known that this was coming and was only a matter of time, it did get here sooner than I expected. I have hypermobile Ehelers Danlos Syndrome (hEDS) from a TNXB mutation. I was incorrectly told by doctors for decades that I was perfectly healthy and my issues were psychosomatic. It wasn't until I did a careful large scale behavioral analysis that I was able to identify similar people and from there the root cause. A $500 (30x) DNA test confirmed it. hEDS is massively under diagnosed, the vast majority never get a diagnosis.

I strongly suspect that most mental problems are physical in nature and most physical problems are DNA related. And even when they're not DNA related, treatment ideas could be gleaned from 'natures large scale experiment'. The number of issues that can be identified from a $100 (1x) test and then subsequently treated is mind boggling. For me, that cost is less than a single doctors visit. This side steps the medical establishment which is slow and in many ways archaic. This will lead to a massive leap forward in medicine.

In other news; I'm also of the opinion that IQ is largely determined by DNA, nature as opposed to nurture, and once that is properly figured out I'm sure designer babies are next. I don't think that is a door that can be kept closed. There is already a black market for it. I'll be watching from the sidelines, I think this is going to get interesting.

I figure DNA works a bit like makefiles. A particular target is only built if it is required somewhere. (And requirements can chain and branch, of course).

So most people realize that height is correlated to diet [given: a functioning gene set; your height is then determined by diet] , strength correlated to exercise [given a fairly broad spectrum that your genes support, exercise will update your strength) , visual accommodation ability to how much you need to accomodate.

But people somehow assume that something as complex and intertwined as an IQ score magically appears, stays constant throughout life, cannot be practiced, and isn't linked to some sort of exercise.

I think most anyone should have a CYP2D6 test if they are considering taking, or taking, medication, it affects so many drugs out there, yet here in the UK, the GP's I have encountered are not familiar with gene<>drug interactions and I had to request it after working it out myself. It's a complex area, but if you happen to be a poor or ultra metaboliser it's a good thing to know. https://www.ncbi.nlm.nih.gov/books/NBK99699/

Does anyone remember the days when some geneticists were saying that 98% of DNA is "junk" DNA? When I heard it I knew it couldn't be true but it's probably going to take another 50 years to figure out how much really does get used.

I can't help but suspect that a lot of the genome is a part of the boot sequence that helps you go from one cell up to all the differentiated organs and tissues and systems.

[+] flobosg|4 years ago|reply
FWIW the study focuses on the coding region of the human genome, i.e., the other 2%.

It is also important to point out that the fraction of non-coding DNA in a genome depends on the organism and is not correlated to complexity. There are multicellular organisms with less than 5% of it as well as unicellular organisms with amounts of DNA orders of magnitude higher than humans.

Boot sequence. Amazing. I've always been interested in how the DNA transcription looks like a Turing machine with the RNAP being the head and the one DNA strand being the tape. Is there any research in that kind of computational analogy or is it just a coincidence?

[+] pfisherman|4 years ago|reply
That is not bad intuition. Another analogy is that coding DNA is like all the function calls - the parts of the code that change data. Non coding DNA is like the all the flow control, conditionals, constants, etc. They don’t directly operate on the data, but have a huge impact on how the program behaves given some input.
[+] xyzelement|4 years ago|reply
Had the exact thought when I read the headline.

What arrogance. "I don't understand what these genes do. Must be junk"

[+] hyperbovine|4 years ago|reply
That hypothesis is a little dated, but it should be noted that the exome (the thing being discussed in this article) is 1% of the overall human genome.
[+] ootsootsoots|4 years ago|reply
Bio-electrics are starting to look at biology the way you describe.

Michael Levin and team at Tufts are instigating regenerative healing by “boot strapping” the process through manipulation of electric fields surrounding cells.

Understanding the extent of network effects will be a big idea in the future. Proving our statistics are probable causes versus mathematical object identification and social debate over the effects.

We’re moving beyond mere taxonomy and catalog of reality into seriously weird science.

Great explainer of the significance of this study by Goncalo Abecasis. Basically human gene knock-outs, courtesy of mother nature.

This study yields tons of gene function leads. Just awesome.

Edit: quote

The data is so rich that we had no more than a single paragraph to summarize association signals relevant to cancer and brain function. Ouch. A tweet won’t do them justice, but @uk_biobank will be sharing all the data with researchers for follow-up.

Not too related, but I got my genome sequenced for fun the other day (< $500 for 30x whole genome), and after a few scrolls through the results (200+ interpretations of my genome in the context of studies like the one linked here), I'm already losing interest.

Ok, so I have a high genetic predisposition for thinness, walking fast [0], and bipolar disorder? So now what? I never noticed except for the thinness. They even scared me with 'you're genetically in the 99th percentile for critical covid disease progression,' but reading the results of the paper in question, it turned out the heritability of the effect under study was only 6%. Thanks for letting me know.

These studies are interesting from a general genomics perspective, but not so much yet from a personal one (with the exception of a few traits that are determined by one or a few well-understood genetic variants. Hopefully this space will expand over the next few decades).

This is precisely right, and for most people it's unlikely that their genome will be particularly useful any time soon.

For an individual, the questions are usually much more focused: for example if I have a baby with my partner, what are the chances that our child will have a recessive genetic disorder? This is answered right now with a carrier screen, where the only genes tested as the genes with variants that are known to cause disease. Much cheaper, much more highly curated, and put together and run entirely by experts in the field, rather than general technologists that are just running samples through a big machine.

Interpretation of the genome will take millions upon millions more individual genomes sequenced, but those individuals will only rarely, if ever, see personal benefit.

you just had the "hey, most of personalized medicine is actually psuedoscience" moment. Welcome to the club.

WHen I had my whole genome sequenced and analyzed by professionals, they were astonished because I didn't have a single risk factor in any known gene. They thought I'd live forever.

[+] pfisherman|4 years ago|reply
In most cases, your sequence info will be useless to you, but in some situations it can have a huge impact, such as predicting how you might respond to epidural anesthesia if you are a woman in labor.

Also, things like personalized immunity therapies for cancers and such are not far off. Unless they completely fail - which is always a possibility in therapeutic development.

[+] pfisherman|4 years ago|reply
Wow, what a time to be alive! For those who are not into bio, this type of information is invaluable for untangling the molecular mechanisms of disease and can provide important clues about where we should intervene with a small molecule or antibody drug to disrupt disease processes.

To give a coding analogy, you can think of this as trying to debug a program written in a language we can’t read. We have no idea what lines are doing what, but there are many different versions / forks of this program floating around. By looking at all the diffs and comparing the outputs, we can start to figure out what some of the code is doing, and which lines we might want to comment out to correct certain types of bugs.

I think DNA data should be considered public data. 99% of our DNA is shared, and the DNA degrees of separation between you and me is ~3. Practically we are all already identifiable from the small sample that exists in genealogy companies and it s been repeatedly done by law enforcement. I think it's bonkers that , after 10 years, companies like 23andme are not allowed to give us health reports because ... what reasons really? Especially in Europe it makes no sense to have such draconian laws about something that's important to everyone's health. Full sequencing costs like $200 today and i m sure millions would be willing to give their data to a public database that would take the field meaningfully forward. Instead what we get is we allow these companies to sell data which should be public domain. The US has its problems with their broken social security - here's a suggestion: fix it. Europe could use its public healthcare advantage to get ahead in genomic research while simultaneously improving the quality of its health systems. Instead we are stuck with outdated privacy laws (yet somehow making tax information public is OK). China could be using their own advantage and databases to get ahead in genomics while we 're still playing hide and seek.

From abstract: “… We discover several risk-increasing associations with traits related to liver disease, eye disease and cancer, among others, as well as novel risk-lowering associations for hypertension (SLC9A3R2), diabetes (MAP3K15, FAM234A) and asthma (SLC27A3)…“
[+] omarhaneef|4 years ago|reply
I think I missed the novel technique they applied.

Surely others try to match particular genes to diseases. Surely that’s one of the pillars of the entire field.

[+] flobosg|4 years ago|reply
The novelty lies in the size of the data set. ~450,000 exomes is a lot.
[+] sjg007|4 years ago|reply
This is neat and will lead to a lot of interesting discoveries. Golden age for genomics is ahead.
[+] wombatmobile|4 years ago|reply
The golden age for genomics has been “ahead” since 1990.

It’s still ahead. We just don’t know which decade will yield the eureka.

Voyages of discovery are like that.

For people with health problems, identifying the genetic stuff contributing to their health issues can be game changing.
[+] dekhn|4 years ago|reply
awful lot of resources were spent to find very little of deep value. Genomics is just marginal gains for each huge new amount of capital invested.
[+] car|4 years ago|reply
Why the pessimism? Lots of really interesting leads are coming out of this study.

A reminder that these sorts of genome-wide studies are not particularly reliable due to the problem of multiple comparisons: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3270946/
[+] gwern|4 years ago|reply
A reminder that these sorts of genome-wide studies haven't used 0.05 but genome-wide significance (10e-8 usually, and 10e-11 in OP) for a decade now for precisely that reason, and have since replicated just fine, thank you very much.
