The future of human genetics will arrive when we understand how each gene in your DNA interacts with every other gene to form who you are. In order to get that understanding we’re going to need to sequence a huge number of genomes. And in order to sequence genomes we’re going to need Complete Genomics. The Mountain View based startup recently went public (NASDAQ: GNOM); with their requisite silent period ended we finally got a chance to tour their facilities and talk again with their CEO Cliff Reid. We were impressed. Complete Genomics isn’t going to conquer the entire world of DNA testing, but the kingdom of human genome sequencing they’ve carved out for themselves looks amazingly well fortified. As far as I can tell, if CG really takes off no one else will be able to challenge them in whole human genome sequencing for years to come. We asked Cliff Reid about the IPO, the genomics market, and some recent advancements in Complete Genomics’ analytical software. Check out his answers in the videos below.
Complete Genomics doesn’t sell a device, they sell a service. Companies like Illumina make DNA sequencers they sell to other companies. Reid and his gang take DNA samples and return with huge amounts of DNA data. Customers never need to deal with the biochemistry. That full service approach helps Complete Genomics focus on increasing the number of human genomes they can sequence for customers, and lowering the price for each. In the following clip, Reid gives us an update on the company, including the success of the IPO, and a look at its production capability and the current price of sequencing human genomes.
Getting to explore Complete Genomics’ Mountain View facilities was pretty amazing. I was struck by the relatively small size of the sequencing lab (though there’s plenty of room for expansion) and the degree to which automation is used. The company can produce 400 whole genome sequences each month, but there’s only ever two technicians working at any given time in the sequencing room. Robotic instrumentation and equipment makes the lab almost seem like a ghost town, but there’s a lot of action going on. I wish we could have turned our cameras on while touring that place, I bet many of you (and all of CG’s competitors) would have loved to see what they had cooking.
While we didn’t get any trade secrets out of Reid, the recipe for Complete Genomics’ secret sauce is pretty clear. This company is about doing one thing and doing it really well. Other big names in sequencing (Illumina, BGI, etc) are looking to handle many different kinds of genetic reading such as examining RNA, sequencing microbes, and sequencing animals. Complete Genomics is doing just one thing – whole human genomes. With that laser-like focus comes the ability to scale their entire company around a central mission. As we’ve said in previous coverage of this company, economies of scale, and single-mindedness in action will help Complete Genomics get cheaper and cheaper, faster and faster.
Eventually that means you’ll have access to inexpensive sequencing for your own genome.
Yet it will take a while to get there. Most of the whole genome sequencing done today is purchased by research labs, not by individuals looking to understand their own health. That’s how it should be. It’s going to take years for researchers to fully understand our DNA and what the variations in our genes mean. Selling genome information to individual customers like you and me would be premature. For now, Complete Genomics is focusing on the research market and helping them make the discoveries that will revolutionize genetics. Once the price per genome comes down, and the science behind genetics is better understood, Complete Genomics will transition into the consumer market. Reid says as much in the following video:
Complete Genomics isn’t 23andMe, Pathway Genomics, or any of the other companies selling genetic tests on the market today. First off, those groups are only testing a small subset of your entire genome for simple variations in individual letters of DNA (single nucleotide polymorphisms or SNPs). Complete Genomics is sequencing whole genomes – all 3 billion letters of DNA. Just as importantly Complete Genomics is waiting until researchers know more about the genome before they try to offer genome sequencing to consumers. That’s different from the current genetic testing companies that the FDA and congress are worried about. Those businesses will sell you genetic tests today, while much of the science is still not completely understood. Don’t get me wrong, I think there’s a place for that. Complete Genomics, however, is waiting until there’s an actual use for you to know your whole genome sequence before they try to sell it to you.
In the years ahead someone is going to have to process thousands (millions?) of genomes before we understand our DNA well enough to make the sort of pinpoint health recommendations that the public expects from this promising technology. Who’s going to sequence all that DNA? My guess is Complete Genomics. Again, getting back to that focus on whole genome sequencing, the company has built it’s entire technology around reading human DNA faster, better, and cheaper than anyone else.
The center of their business is their fluorescent read technology, which analyzes nanoballs of DNA that correspond to different A, C, T, G ‘letters’ of genetic code (learn more about the nanoballs on the Complete Genomics website). In Reid’s words they, “use silicon to read silicon”. A silicon based semi-conductor camera is precisely aligned with a different silicon wafer full of tiny pockets where the nanoballs sit. When I say tiny, I mean tiny – those pockets are just 300 nanometers across. The camera only has to use a few pixels (soon even fewer will be needed) to optically read each nanoball and determine if it contains an A, C, T or G.
According to Reid, Complete Genomics had reached the limits of optical reading technology. They are (or soon will be) using as little digital information to read each letter of DNA as you possibly could. The best other companies could probably do is match them. Add in the fact that their automated reading technologies are getting faster, and their analytical software is getting smarter, and you can see that Complete Genomics is quickly making itself the foremost leader in whole human genome sequencing.
Even if another company finds a way to sequence whole genomes with the same speed as Complete Genomics, I still think Reid and his cohort will come out on top. By focusing on just one product (whole human genomes) Complete Genomics will develop an unprecedented amount of experience in their field. They’ll discover all the little undiscovered idiosyncrasies that make human genomes unique compared to other sequencing projects and they’ll understand those twists and turns better because human genomes will be the only thing they work with. Single minded focus will help Complete Genomics learn all the tricks, and this will help make them more streamlined, faster, cheaper, and better at analyzing human genomes.
In the following video, Reid discusses Complete Genomics’ technology. Recently, the company announced a particularly exciting advancement in their software for digital analysis of DNA. Now when a researcher sends a genome to be sequenced CG will include information about copy number variation and structural variation – data that can illuminate where in a cancer cell genome that DNA has gone bad. Basically Complete Genomics is making it much easier for scientists to translate genomic data into insights about the nature of cancer. Coupled with a growing assortment of open source analytical code (CGA tools), Complete Genomics’ software is accelerating research into genetics. Pretty cool.
Other companies, like Ion Torrent, have developed DNA reading technologies that use semiconductors rather than optics to sequence genes. These CMOS based sequencing technologies have been hailed as the next step forward in genetics. As you saw in the video, Reid explained the reason why they aren’t afraid of semi-conductor based DNA readers. Can we all say that reason together? Complete Genomics only has to worry about whole human genome sequencing. While we toured the Complete Genomics facility, Reid pointed out that if you calculate how much current CMOS tech will cost to sequence a full human genome, the price would be many hundreds of thousands of dollars (or more). The big advantage semiconductor sequencing has is that it can fit on a desktop. Complete Genomics doesn’t want to fit on a desktop and they don’t want to be portable. They just want to sequence whole human genomes.
The same logic applies to those companies looking to push the boundaries of how much DNA they can read at a time. In the sequencing field, there are both ‘long reads’ and ‘short reads’. The human genome has more than 3 billion base pairs (those A,C,T, G letters). In order to sequence a genome you end up first sequencing smaller chunks of those letters, and then pasting those chunks together to get the full 3 billion letter code. The shorter the chunks you use, the more you need to double check your work and the more complex it is to paste things together. ‘Short reads’ sequence each chunk multiple times (10x or more for some Complete Genomics projects) while ‘long reads’ get away with doing that less. Long reads, however, also tend to be slower and more expensive. As Reid explains, long reads are good for some things, but Complete Genomics isn’t into those things. They have improved software that makes short reads the most economic way for them to proceed with human genomes.
This company knows exactly what it wants to do. And it is doing it really well.
That doesn’t mean I’m completely free of concerns. I’ll stop my blatant cheerleading for a second and do a little math. Reid didn’t give us an exact total for how many genomes they’ve sequenced (that’s ok, we know from other press materials that the number is more than 500 – damn impressive) but he did tell us that his current capacity is around 400 genomes per month. Those sell at a price of $10,000 each (or less if bought in bulk). Assuming there’s enough market demand (which I think there is), that means with current levels of production Complete Genomics could make around $4 million a month in revenue. So, maybe $48 million a year? Remember, even as Complete Genomics increases its production to drive up their revenue, the price per genome is planned to recede. This company has spent “tens of millions” on improving their software, and according to their own reports they spent more than $20 million in Q3 of 2010. Is $48 million per year enough for Complete Genomics to grow? Reid says they are very happy with their IPO, but I know that if I were in his place I would have been even happier if they had raised their original target of $80M instead of the $50M or so they got.
I think this next year is going to be a critical time for the company. Depending on funding and revenue they could have to stay on a conservative growth curve. Or, if they secure the finances, they could really ramp up – trust me, the technology looks like it is more than ready.
I really want a whole genome sequence to cost less than $1000 and not simply because I ‘m itching to peer at my own software code. By the time we hit that price point, researchers will have had the opportunity to look at thousands (tens of thousands?) of genomes and finally get the data they need to puzzle out some of the secrets of our DNA. That future may be nearer than we think. For now, Complete Genomics looks like the company that is going to take us there. I can’t wait.
