So you need some DNA sequencing? (pt 1.)

There's an absolutely brilliant map and website devoted to taking a census of DNA sequencers around the world, and through it, you can monitor the tug of war between the placement of instruments in large DNA sequencing centers, and in individual labs (or core labs) on a onesie-twosie basis.

(The map may be a little dated - it shows only 15 sequencers @ BGI, for example - but the brilliance of the map is in how the data was generated. Do a little web surfing for the WWII spy technique that spawned the map.)

Anyway, a VERY interesting story is told when looking at the USA map (select USA under the country pull-down. Unfortunately, I can't link to this specific page.) The sequencer census really indicates who and what are on the edge of the genomic revolution.

A rough read of who's ahead by sequencer placement:

Boston: 129 (Broad Institute = 104)
St. Louis: 85 (includes 11 at Monsanto)
San Francisco Bay Area: 58
Washington, DC area: 51 (with an additional 23 in nearby Baltimore and Frederick, MD.)
NYC area: 47 (includes 18 @ CSHL on Long Island.)
RTP, NC: 37
Houston: 35 (driven by MD Anderson.)
Toronto: 33
Southern California (LA + SD): 27
New Haven, CT: 23 (birthplace of 454 and IonTorrent.)
Philadelphia: 22
Albuquerque, NM: 19 (Sandia)
Montreal: 18
Memphis: 12
Seattle: 5

most other US metropolitan areas and universities had 1-5 DNA sequencers listed.

(Note: some of the math above is fuzzy, as figures change slightly depending on how far you drill down on the map. Plus, the math is skewed by self-reporting and non-reporting. For example, there is a paucity of hardware listed in 'PharmCountry' (NJ & eastern PA) and there's virtually no privately owned sequencers in the Bay Area, but you can be sure that both Big Pharma and Genentech have some sequencing hardware on campus.

What does this all mean:

-you can see which cities are in position to lead the genomic revolution, and which are likely to be laggards. For example, according to the map, there is only 2 DNA sequencers in the city of Chicago. There's roughly 25X more genomic activity on the i-270 corridor outside DC.


  • I was surprised by the strong figures in St. Louis and RTP. Both locations have strong ag-bio efforts, so you might be able to extrapolate that the earliest exciting NGS uses will come from ag-bio, and not cancer genomics.
  • Anyone else as surprised as I am that NYC was in the top 5? Certainly there is great science at places like Rockefeller, MSKCC, and such, but I wouldn't have guessed top 5. With some announced initiatives, NYC should stay near the front.

-you can see funding philosophies in action (if you squint). There is a tremendous amount of hardware in Canada relative to population, representing governmental support skewed towards hard assets rather than funding annual research. (And the good work of bodies like Genome Canada.) However, with the rate of technological innovation in sequencing, hardware represents a quickly depreciating asset. Maybe the better use of the funds was to pay for outsourced sequencing. (Perhaps this was the case in California, where the inverse was present - less hardware than you might expect.)

-if I had to bet which institution will lead in the adoption of DNA sequencing in patients, MD Anderson would be my first bet. My quick survey suggests that they're the practicing center with the most NGS hardware. Yale isn't far behind.

-on the other hand, some NCI comprehensive cancer centers were extremely lame, including my hometown University of Virginia, Northwestern U, and OHSU. 1 sequencer each? Lame!


Tomorrow I'll do some analysis based on the type of hardware, and take a guess at what this means for adoption. I'm especially interested in analyzing the question of what the distribution in sequencing is likely to be between CRO/service providers and sequencing with internal assets.

  1. Your comment about St. Louis is a bit off. Washington University's genome center has long been a leader in sequencing & is one of those centers which try out a lot of new technologies. An awful lot of that goes into cancer genomics; they have consistently been a leader in the field (first WGS of matched tumor-normal pair for example).

    St. Louis is also home to a significant outsource provider, Cofactor Genomics, which was a spin-out of sorts from Wash U.

    In addition to the self-reporting bias, there are also some duplications & lag in clearing sequencers that have been retired. Private companies which are not service providers are not represented well at all. Ion Torrent as a platform has consistently been underreported.

    It is a brilliant map!
