But I do want to sequence it using a third-party that gives me all the raw data. I live in Europe and I'm just a simple consumer. Does anyone know how I can do this? What service would I use / you can recommend?

Them not keeping it on their side would be a huge bonus of course but not sure I can ask for that much.

  Don't forget to change your DNA when the third party's database will eventually leak. (see the 21andMe's data leak: https://en.wikipedia.org/wiki/23andMe_data_leak)

  • vintermann

    today at 10:20 AM

    They did not leak their database, the attacker guessed some user passwords and scraped those people's match lists.

    I don't think they even got their hacked user's test results - you can download those from 23andMe, as GDPR requires, but it's a "request your data" process which isn't so easy to do at scale without people noticing.

    23andMe is also not NGS sequencing, so you get only a couple of 100000 letters randomly* distributed across your whole genome.

    • jefftk

      today at 10:37 AM

      I know you put an asterisk, but to make it clear: these locations are very far from random. They're the most informative positions, which is why we check them.

      • vintermann

        today at 10:46 AM

        Well, they're what 23andMe thinks are most informative, for the things they think their customers care about. Or thought; for compatibility reasons they can't change their SNP panels very often or too much.

        And the interesting positions are still reasonably randomly distributed by nature :)

        • bonsai_spool

          today at 4:37 PM

          I don't do SNP design but I don't think 23andMe made their own chips at first (if they have ever). SNPs are chosen based on being informative for population discrimination, with traits being overlaid afterwards

          • vintermann

            today at 5:19 PM

            I could be wrong, but I do believe they get to choose. What I do know is that none of the big testing companies test exactly the same SNPs, there is some overlap but every test is different. They also change their SNP sets from time to time, 23andMe has changed at least 5 times, and interestingly, their current test isn't the biggest (it tests fewer SNPs than some of their earlier ones).

        • doctorpangloss

          today at 4:48 PM

          well SNPs aren't useful for drug development, commercialization, medicine, etc. you want whole genome or whole exome sequencing for stuff that is future-looking. they use a process for the present day (quickly becoming the past) of okayish drugs instead of sequencing for a future of cures.

            It turns out that it's more valuable for advertisers to learn if you actually smoke, than that you have a genetic propensity for smoking. Your genotype is just useful for figuring out your phenotype, and in the vast majority of cases, your genetics (especially not at the resolution offered by 23andMe) are not a shortcut to learn your behavior, which is what they're really after.

  YSEQ is basically a mom- and pop shop, two German scientists who helped set up Family Tree DNA's labs in Texas then went home to start a small competitor (I think there was some sort of disagreement or conflict) in the space of high-resolution Y DNA sequencing for genealogists.

  They also do high resolution full genome sequencing on request. But be warned, it takes a long time, and they reserve the right to cancel your order if you complain about how long it takes!

  They're not the cheapest option, but when it comes to privacy for Europeans, I think they're as good as they come. You want a bit of "difficult to work with" when it comes to privacy.

  • vintermann

    Some DNA companies (FTDNA for one) play fast and loose with this.

    FTDNA gives you a vcf file, which contains the variant calls, but not the raw reads which those calls are made from (as in the BAM file). They do keep that data, because they charge extra for a BAM file download. It's almost certainly against the GDPR. Worse, I think they do it for anticompetitive reasons - they own the largest Y-DNA tree, and don't want you uploading your raw data to competing trees (in particular YFull).

• shevy-java

  today at 7:33 AM

  Many companies offer that. In the local area they have e. g. mail-like stations where you give out your order and they give you what you need (e. g. if it is a plasmid, it is mailed into storage boxes often on the same day or next day).

  "Not keeping it on their side" ... well. If they sequenced it, they have data in their computer, right? How could you avoid that? I don't see this as possible, it depends on trust (and whether you really care about that).

  > What service would I use / you can recommend?

  I won't recommend anything as I do not want to be an ad-amplifier, but my personal rule of thumb is that those companies that are affiliated with science clusters, are often chosen because they offer high quality (and to some extent because of corruption e. g. xyz knows abc, but this is IMO the smaller part, usually it is quality/speed/ease of use).

  • anoneng

    today at 4:26 PM

    Much like many cameras process and discard the RAW sensor data after processing to pixel data if not further compressing and discarding the processed pixel data to a lossy image format, even more so the raw BAM sequencing read data is vastly larger than processed VCF files. Even many companies that retain that data are liable to archive it offline rather than keep the raw reads permanently accessible online. There are real costs involved and a business case is needed for keeping that data. Especially with a decent privacy policy or regulations storing 100G or multiples of that online for free and downloading on demand is a significant compared to the entire cost of sequencing.

  • crote

    today at 8:55 AM

    Files aren't magically stored forever.

    They could have the sampling machine write to an SD card and mail that back, or store it with a one-time-use link like pwpush.com, or have it expire & self-delete after N days like WeTransfer.

    You of course have to trust that they aren't secretly keeping their own copy on S3 forever, but that'll always be a risk, and it can probably be contractually enforced and audited.

    "Not keeping it on their side" ... well. If they sequenced it, they have data in their computer, right? How could you avoid that? I don't see this as possible, it depends on trust"

    First it depends on the contract, if it states they have the right, then they can and will legally use it.

    If the contract would say no - then they would have a much harder time making use of that data, as it would be illegal.

    Well if you have this problem, then having the plumber over is a sunk cost. You're paying them regularly to clear the sewer, and their snake will come back with root matter in the bit. Put that sample in a zip-lock bag and call me. I'll come over, take the sample, and identify the plants near your sewer line. If I get a match, I'll sell that info to you for $100.

    Once I figure out how to make it work at all, I'll build a network of plant nerds and teach them to do the same in their cities, and pivot to providing lab services and training for them. Much of the time no sequencing will be required, just a microscope and knowledge of what's growing nearby. But if they have more than one plant of the same species, sequencing will be necessary.

    Fingers crossed they're not clones, though I suppose I could do lab testing for that as well, and then I maybe you'd have to kill multiple just to be sure you got the one. In that case, hopefully I'd have at least narrowed it down for you. Probably would just deny the job if the odd of being helpful are low, like if you have 50 clones of the same tree all growing along your sewer line, then I can't help you, it's time to start saving for a liner or a replacement.

      Fastest/cheapest sequencing based method would likely be to collect samples in DNA preserving agent (zymo DNA shield is decent for this), then have an automated platform for extracting DNA and preparing amplicon sequencing libraries (rbcL + matK probably?). Worth having a look at how Plasmidsaurus did this, they did have a similar service for microbiome analysis (https://plasmidsaurus.com/sample-prep/microbiome#16S-extract... - looks like they don't accept raw samples anymore though...). Oxford nanopore sequencing is a decent technology for this as it's fairly straightforward to get working and easy to scale :) As an added bonus, you could perhaps also carry out 16S sequencing in parallel from the sample to get an idea of the microbiome of the sewer.

I wish this had some discussion of the results. The earlier reports about this sensor and process were very mixed. It’s a cool process either way, but I’d like to know how usable the real world output can be.

I want to sequence, but I absolutely do not want any company or government or church to have access to my data. When the author says:

> "I have a VCF, I can run it through tools like VEP, ClinVar, gnomAD, PharmGKB (highly recommend), Gene Inspector, or Claude"

  Untrue in the cases of VEP, ClinVar, gnomAD. These are either offline, open-source tools or databases. You can download or query these and no one would be the wiser.

  Claude on the other hand - yeah you are giving your data away. But that step really isn't necessary.

  By running a standard pipeline you could get a VCF (File containing the Variants in your genome) and each variant would be annotated. You can check all the annotated genes and figure out if these variants are pathogenic, likely pathogenic, likely not pathogenic or benign.

  Per the article, ONT sells tiny sequencers that all this genre of "Omg I just sequenced my genome" posts use. They've been around for a decade or so. A commercial lab will give you 30x illumina sequencing for maybe 5% of the cost of this post.

• searine

  today at 3:03 PM

  As an 'at home' science project? Totally do-able, but very expensive. I did it as part of epidemiological field with a backpack of materials, so you can definitly do it at home.

  As a useful genome? Marginal. ONT will need a couple runs to get complete human genome coverage and the substitution error rate is still high compared to short reads. For a fraction of the price and effort you can get your DNA resequenced at 10 times the quality.

  I guess if you are super-ultra paranoid you can do it all yourself at home, but honestly. You're not that special, and if someone really actually wanted your genome that bad they'd just take it from a used coffee cup.

As someone with experience (albeit almost 20 years out of date) experience of wet lab DNA collection and sequencing - this stuff is hard, you will fail a lot, and you will fail a lot more if you don't have an extremely clean environment to do this in. And once you have data, you should be asking yourself how accurate it is given the environment you collected it in, you should be looking at correlated sequence errors that are not taken into account[1].

But also: genetic counselling is a real thing that real people study. Please don't ask an LLM questions about what your genes are going to do to you without having access to someone who has the ability to contexualise the data and put you in touch with relevant experts. I have a PhD in this and I would not trust myself to be able to interpret data about myself in a detached and rational way.

(And: why is the link to Molecular Biology of the Cell to the 6th edition, when the 7th came out 4 years ago? Random fact: the first three editions were co-authored by my supervisor during my first PhD attempt, who went on to demonstrate that Roger Penrose's ideas about the importance of microtubules in chemotaxis in E. coli were absolute bullshit. Great guy)

[1] I spent a while analysing very early (by commercial standards) Illumina data in 2007, and being able to align stuff to reference genomes made it possible to identify certain biases. Nanopore technology is likely to have more of those, and if you don't have the ability to take those into account you may have a very bad time

• epgui

  > this stuff is hard, you will fail a lot, and you will fail a lot more if you don't have an extremely clean environment to do this in

  The Oxford Nanopore sequencing technology is one of the most robust to use. You need to buy some kit - but defo doable. Nothing compared pouring your own gel and doing radioactively labelled Sanger reactions :-)

  Though you could just go to an sequencing company that services labs ( that just does sequencing outsourcing - rather than a personal genome company ).

  Totally agree on the dangers around interpretation.

It might make even more sense once we get to the point of a wider use of encoding the data into dna. For now we have these few commercial players in the field that cad do it (eg look up dna microfactory for storage archiving), IIRC genomika was saying they can do an MB for a 100-200eur.

Is this the same guy behind https://iwantosequencemygenomeathome.com/ ?

[Edit: Apparently no. That link is by Seth Howes, who also shared the OP post though: https://x.com/SethSHowes/status/2074231119730430203 ]

  It's quite a bit more difficult with poop. A rather large proportion of the DNA in poop isn't from the creature that pooped it. (mostly bacteria)

    And you'd need the DNA of all dogs to boot (unless they are already somehow stored when a dog is registered). But generally speaking, I do like the idea. Also for horse poop which is pretty common on roads here in the countryside.

What is the accuracy in this ? Aka if I run the experiment 10 times how many differences will i get? I don’t have a physical sense on what would be a good number.

  You would get a lot of differences, but the errors would cancel each other out with enough depth of coverage.

  This technology's baseline accuracy is around 95% per base, so 10x reads of every segment in the sample would give >99% accuracy for each base after aligning the reads with each other.

    This assumes random errors, which IIRC isn't the case for Oxford Nanopore.

• Jules-Bertholet

  Oxford Nanopore unfortunately has a high error rate (3-5%) compared to other sequencing technologies. And the errors are non-random

    This is simply not true, advances in basecalling and using Duplex give you >Q25

  • Gethsemane

    For most DNA it now sits at ~Q20 (1%) which is a big improvement - there was also some hacky stuff like HERRO and duplex sequencing which improved it substantially. For routine genome sequencing it's definitely suitable, and the long-read advantage helps resolve some of those trickier regions

one main marketing leverage of 23andMe, AncestryDNA, etc are fulfilling the curiosity of people who want to know which part of the world their genes are from. I guess that dataset should be preparatory.

• sergey-a

  Problem with those providers - they only check 700K positions out of 3 billion and there is no mapping quality or allelic depth data in those dataset and this is critical for assessing whether the detected variant is a false positive or real.

  It's not suitable for health investigations since most of DNA is not sequenced and genotyping technology is known to produce high rate of false positive for rare mutations.

    It's a bit ironic, since FTDNA and MyHeritage (which uses FTDNA's lab) have switched to NGS now, so they presumably could deliver those notorious "health insights", at least better than 23andMe. But they aren't in that market, and 23andMe shows no inclination to switch. They're probably licking their wounds after the user hack and buyout fiasco.

I'm too afraid I would learn something awful about myself.

• vintermann

  That's unlikely, but I do think that the health benefits of full sequence testing yourself are largely hypothetical at this point anyway. Unless you're a competitive athlete maybe?

  It's genealogy it's useful for. But genealogy, it's really useful for.

  Unfortunately you’d have no power to correct it. Even if such a thing were possible. I hope that changes.

  • vintermann

    today at 10:35 AM

    You have no power to correct something with gene editing, true, but there may potentially be preventive action you can take. It's all largely hypothetical today anyway, most things you care about (e.g. cancer, Alzheimer's) you can't usually tell very reliably if you're going to get from a DNA test.

  Nothing about this is the future. Sequencing at home will not solve any major problems. It's mainly a fun exercise to demonstrate that sequencing has been commodified.

    I disagree, I sequenced with nebula genomics years ago.. you can understand risk factors for various problems so that you can start interventions that make sense way in advance.

    Knowing exactly why I have high LDL because of a specific mutation on my DNA is very much the future, imo.

Can CRISPR also be done at home this cheaply?

Seems like maybe of the 3 dystopias: AI, Global Warming, Bio-warfare. That this is demonstrating that the home grown virus is closer than we think.

This feels like the acme of narcissism. How much time and money are people willing to spend on navel gazing?

• vintermann

  today at 10:42 AM

  True story, I found a god damn tick in my navel yesterday. Sometimes a bit of navel gazing can be healthy, figuratively and literally.

  On a reasonable level, navel gazing (the figurative kind) is maybe better called self-reflection. I use DNA for genealogy, and it seems to me from the people I meet, that many get a healthier approach to our identity once we learn more about our genetic background. Identity politics, collective identity building around ancestry - identity building of all kinds really - needs simple stories. And the stories DNA tell are never simple.

  When you are taking care of your health, and need to learn more about your built-in limitations is it still narcissistic?

  I don't get you at all.

  Is going to your doctor or eating better food "navel gazing"? Predispositions to some diseases can be read from your DNA. Remember Angelina Jolie undergoing preventive mastectomy because she had a high genetic risk for breast cancer? Well, so do many non-celebrities.

  Then there is the specific case of people who may suspect that their bio-parents are someone else, and there is nothing weird about wanting to know where you actually come from.

  Literally left the article to come here and say this.

> The near-term value is turning a static genome into something queryable

Ok. So ... how exactly is this valuable?

If you realise "hey, I gots Huntington disease", this is going to make you feel better? Or any other incurable disease? I am not disputing that knowing the sequence is useless in general, mind you. I am specifically asking WHY it is necessary to know your genome sequence. This seems to be a simplification or just a "having reached a milestone". But then they don't really explain WHY it is useful. None of the bulletin points he listed is really useful:

> Which variants do I have?

And this is useful ... how exactly?

> Which genes and pathways are affected?

And ... this matters why?

> Which medicines might I metabolize differently?

Ok, so this has a potential use case here, since he can choose to avoid specific drugs. How useful that really is in practice is unclear. (Don't confuse drug companies trying to convince YOU that personalized medicine is important on THEIR use case.)

> What rare variants should I take seriously?

Seriously ... how? Ok, you avoid some compounds. Now what.

> Where does the model know nothing yet?

Great, so a model that is limited, but now I need to burden myself with having to know where that limitations are. So my brain just has extra processing to do, without getting anything useful in return.

> the “edit yourself with CRISPR” will most likely follow

Except that they have not solved the off-target cleavage yet. Besides, they milk the prices anyway. DNA manipulation should be safe, secure, correct and affordable. None of that is the case right now. They publish papers where CRISPR has solved everything, but then fail to explain why it isn't already used by billions. And there are reasons as to why.

> Give your genome to Claude Code

Oh my god ... AI becomes your dependency here.

Note that the step-by-step guide is actually not totally useless, as it can give a basis for real work. But I highly doubt that untrained people will easily be able to go through those steps. Everyone is a master in the lab now? RNA is easy to handle? Guess then one would have to explain why RNase A is used (ok ok it's not playing a huge role here since DNA is the target of isolation, but it is more of an example of how many things can go wrong, and there is not really an explanation of why xyz is used; this looks like an AI step-by-step guide. AI really makes people dumber).

The "non-random errors" point buried a few replies down deserves to be the headline, not a footnote. With Illumina, 10x coverage genuinely washes out errors because they're closer to independent per-read noise. With Nanopore, errors cluster at specific motifs (homopolymers, certain k-mers) due to how the pore physically reads the strand — so the same systematic mistake shows up across most of your reads at that position, and naive majority-vote consensus won't fix it. You need a basecaller/consensus model trained to correct for those specific failure modes (which is exactly what the current-gen Guppy/Dorado models try to do), not just "more depth." That distinction matters a lot for a home setup: coverage is cheap, but knowing where your specific errors are systematic vs. random is what determines whether "buy more reads" actually gets you to clinical-grade accuracy or just gives you a very confident wrong answer.
