Graphs Show Costs of DNA Sequencing Falling Fast 126

kkleiner writes "You may know that the cost to sequence a human genome is dropping, but you probably have no idea how fast that price is coming down. The National Human Genome Research Institute, part of the US National Institute of Health, has compiled extensive data on the costs of sequencing DNA over the past decade and used that information to create two truly jaw-dropping graphs. NHGRI's research shows that not only are sequencing costs plummeting, they are outstripping the exponential curves of Moore's Law. By a big margin."

      Sequencing has been where the focus on cost has been going. It doesn't make much sense to try and reduce the cost of analysis when it takes a very long time and a huge amount of money to accomplish. The graph was hard to read, but at this point with the cost well over $10k there's a lot more that has to be done before analysis is worth spending a lot of time economizing.

      But as it gets cheaper more and more of the focus will be on the analysis side. And the cost of analysis will come down, given that insurance isn't going to cover the sequencing at this point, analysis is moot in most cases. As more research analyzes sequenced DNA I'm sure tricks and such will be discovered to bring the cost down. But right now you're dealing with low volumes and as such cost is higher than it will be with higher volumes.

      • Define "cost of analysis". I paid 23andme.com $100 per person (myself, my wife, and my brother) to sequence 1 million SNPs per person using Illumina's V3 chip (plus $5/month/person for as long as we have accounts with them) and to provide current and future research data with regards to those SNPs. That is *super cheap* for the kind of data I'm getting out of it (I'd be happy to post an imgr link with an anonymized print-version of the report, although I guess it doesn't matter since I've already uploaded t

          to sequence 1 million SNPs per person

          Actually, they're not sequencing.

          They're checking.

          The way 23andme and most personal genome companies work is that they have those genochips (Illumina) with one million DNA sequences on them, and they check whether or not your DN has one of those sequences.

          If you have a SNP not on the chip (well, you have lots of SNP not on the chip), it won't list anything. If, at a given chromosome locale, they have "all" of the "known" SNP, but you happen to have a mutant variant not on their lib, then you're not detected.

          "Sequencing" involves taking your DNA, and getting every sequence, no matter what. And that's still long and very expensive. We're in the era of the "thousand genomes", meaning we expect in a couple year to complete a thousand full sequences. Of course, 10 years later, we'll sequence everyone, but, so far, it's still a way out.

          Progress in SNP chips, though they were a big breakthrough when introduced and remain very important in research, has been pretty static compared to the dramatic speed with which 'next generation' sequencing technologies have brought down the cost and increased the amount of data we have to cope with. Whole genome sequencing is on an entirely different scale - 3 billion bases rather than a million. Even an 'exome' (the sequence of all the actual genes in your genome) runs to about 40 million bases.

      It's computationally expensive and pretty much subject to Moore's Law (though improved algorithms like Burrows-Wheeler alignment have helped to speed things up in the last couple of years). So it's getting cheaper, but not fast enough to keep up with the expected deluge of data. If you're just interested in sequencing a fixed number of genomes you benefit from both cheaper/faster sequencing and cheaper/faster processing power. But if you're a major genome cen

      Even in research, most of the sequencing at whole genome level is outsourced to big companies (like, for example, Complete Genomics) since investing in the capabilities, machinery and computer power to sequence whole genomes is simply too big for sequencing one or a few individual genomes (you currently need to invest a few millions to get started with the sequencing of whole genomes). You can DIY sequencing of small fragments (for example, to determine whether a known genetic cause of a hereditary disease

      I myself paid for 23andme.com to do genetic profiles for myself, my wife, and my brother. $100/person and then $5/month/person ongoing as they add more research each month (come on, $5? Cheap! for the research data they add, although I guess some people don't see the value).

        my emphasis:

        What is the difference between genotyping and sequencing?

        Though you may hear both terms in reference to obtaining information about DNA, genotyping and sequencing refer to slightly different things.

        Genotyping is the process of determining which genetic variants an individual possesses. Genotyping can be performed through a variety of different methods, depending on the variants of interest and resources available. At 23andMe, we look at SNPs, and a good way of looking at many SNPs in a single individual is a recently developed technology called a “DNA chip.”

        Sequencing is a method used to determine the exact sequence of a certain length of DNA. Depending on the location, a given stretch may include some DNA that varies between individuals, like SNPs, in addition to regions that are constant. So sequencing is one way to genotype someone, but not the only way.

        You might wonder, then, why we don't just sequence everyone's entire genome, and find every single genetic variant they possess. Unfortunately, sequencing technology has not yet progressed to the point where it is feasible to sequence an entire genome quickly and cheaply. It took the Human Genome Project over 10 years' work by multiple labs to sequence the three billion base pair genomes of just a few individuals. For now, genotyping technologies such as those used by 23andMe provide an efficient and cost-effective way of obtaining more than enough genetic information for scientists—and you—to study.

        To be sure you have gained interesting information for your $200, but you have neither your sequence, nor a complete list of differences from a reference human sequence, which of course if you did would give you your sequence.
        23andme only gives you a list of many SNPs.

    We've been observing this decrease over the last few years at our sequencing lab too. Some people might find it fascinating, but I, as a bioinformatician, find it frightening.

    We're still keeping up at maintaining and analysing our sequenced reads and genomes at work, but the amount of incoming sequencing data (currently a few terabytes of data per month) is increasing four-to-five-fold per year (compared to doubling each 18-24 months in Moore's law). Our lab had the first human genomes at the end of 2009 after waiting for almost 9 years since the world's first human genome, now we're getting a few genomes per month. We're not too far away of running out of installing sufficient processing power (following Moore's law) and no longer being able to process all of this data.

    So yes, the more-than-exponential decrease in sequencing costs is cool and offers a lot of possibilities in getting to know your own genome, advances in personalized medicine, and possibilities for population-wide genome sequencing research, but there's no way we'll be able to process all of this interesting data because Moore's law is simply way too slow as compared to advances in biochemical technologies.

      I assume you're talking about incoming data, not the final DNA sequence. As I understand it the final result is 2 bits/base pair and about 3 billion base pairs so about a CD's worth of data per human. And if you were talking about a genetic database I guess 99%+ is common so you could just store a "reference human" and diffs against that. So at 750 MB for the first person and 7.5 MB for each additional person I guess you could store 2-300.000 full genetic profiles on a 2 TB disk. Probably the whole human ra

        Yes, the incoming (and intermediate) data sets are huge. You don't just sequence each base once, but 30-50 times over on average (required to call variants accurately). And you don't want to throw this data away, since analysis algorithms are improving all the time. But it's true that the final 'diff' to the reference sequence is very small, and has been compressed to as little as 4Mb in one publication:

        The incoming data is image-based, so yes, it will be huge. Regarding the sequence data: yes; in its most condensed format it could be stored in 750MB. There are a couple of issues that you're overlooking, however:
        1. The reads aren't uniform quality -- and methods of analysis that don't consider the quality score of a read are quickly being viewed as antiquated. So each two bit "call" also has a few more bits representing the confidence in that call.

      Interesting. I view this from a completely different perspective: if DNA sequencing really is outpacing Moore's Law, that just means that the results become disposable. You use them for your initial analysis and store whatever summarized results you want from this sequence, then delete the original data.
