Welcome to the genomic revolution | Richard Resnick | TEDxBoston

  • 0:11 - 0:12
    Thank you.
  • 0:12 - 0:13
    Ladies and gentlemen,
  • 0:13 - 0:15
    I present to you the human genome.
  • 0:15 - 0:19
    (Applause)
  • 0:19 - 0:23
    Chromosome one -- top left,
    bottom right -- are the sex chromosomes.
  • 0:23 - 0:26
    Women have two copies
    of that big X chromosome;
  • 0:26 - 0:29
    men have the X and, of course,
    that small copy of the Y.
  • 0:29 - 0:33
    Sorry boys, but it's just a tiny
    little thing that makes you different.
  • 0:36 - 0:39
    So if you zoom in on this genome,
  • 0:39 - 0:42
    then what you see, of course,
    is this double-helix structure --
  • 0:42 - 0:45
    the code of life spelled out
    with these four biochemical letters,
  • 0:45 - 0:48
    or we call them bases: A, C, G and T.
  • 0:48 - 0:51
    How many are there
    in the human genome? Three billion.
  • 0:51 - 0:52
    Is that a big number?
  • 0:52 - 0:54
    Well, everybody
    can throw around big numbers.
  • 0:54 - 0:56
    But in fact, if I were to place one base
  • 0:56 - 1:00
    on each pixel of this
    1280x800-resolution screen,
  • 1:01 - 1:04
    we would need 3,000 screens
    to take a look at the genome.
  • 1:04 - 1:05
    So it's really quite big.
  • 1:05 - 1:07
    And perhaps because of its size,
  • 1:07 - 1:10
    a group of people -- all,
    by the way, with Y chromosomes --
  • 1:10 - 1:12
    decided they would want to sequence it.
  • 1:12 - 1:14
    (Laughter)
  • 1:15 - 1:19
    And so 15 years, actually,
    and about four billion dollars later,
  • 1:19 - 1:21
    the genome was sequenced and published.
  • 1:21 - 1:24
    In 2003, the final version was published,
    and they keep working on it.
  • 1:24 - 1:26
    That was all done on a machine like this.
  • 1:26 - 1:30
    It costs about a dollar for each base --
    a very slow way of doing it.
  • 1:30 - 1:31
    Well, folks, I'm here to tell you
  • 1:31 - 1:33
    that the world has completely changed,
  • 1:33 - 1:35
    and none of you know about it.
  • 1:35 - 1:38
    So now what we do is take a genome,
  • 1:38 - 1:39
    we make maybe 50 copies of it,
  • 1:39 - 1:42
    we cut all those copies up
    into little 50-base reads,
  • 1:42 - 1:45
    and then we sequence them,
    massively parallel.
  • 1:46 - 1:49
    Then we bring that into software
    and reassemble it,
  • 1:49 - 1:50
    and tell you what the story is.
  • 1:50 - 1:53
    So to give you a picture
    of what this looks like,
  • 1:53 - 1:55
    the Human Genome Project:
    3 gigabases, right?
  • 1:55 - 2:00
    One run on one of these modern machines:
    200 gigabases in a week.
  • 2:00 - 2:02
    And that 200 is going
    to change to 600 this summer,
  • 2:02 - 2:04
    and there's no sign of this pace slowing.
  • 2:07 - 2:10
    The price of a base, to sequence a base,
  • 2:10 - 2:13
    has fallen 100 million times.
  • 2:13 - 2:16
    That's the equivalent of you filling up
    your car with gas in 1998,
  • 2:16 - 2:18
    waiting until 2011,
  • 2:18 - 2:20
    and now you can drive
    to Jupiter and back twice.
  • 2:20 - 2:24
    (Laughter)
  • 2:25 - 2:26
    World population,
  • 2:27 - 2:28
    PC placements,
  • 2:29 - 2:31
    the archive of all of medical literature,
  • 2:32 - 2:33
    Moore's law,
  • 2:34 - 2:35
    the old way of sequencing,
  • 2:35 - 2:37
    and here's all the new stuff.
  • 2:37 - 2:38
    Guys, this is a long scale;
  • 2:39 - 2:41
    you don't typically see
    lines that go up like that.
  • 2:42 - 2:45
    So the worldwide capacity
    to sequence human genomes
  • 2:45 - 2:48
    is something like 50,000 to 100,000
    human genomes this year.
  • 2:48 - 2:51
    We know this based on the machines
    that are being placed.
  • 2:51 - 2:54
    This is expected to double,
    triple or maybe quadruple
  • 2:54 - 2:56
    year over year for the foreseeable future.
  • 2:56 - 2:58
    In fact, there's one lab in particular
  • 2:58 - 3:01
    that represents 20 percent
    of all that capacity:
  • 3:01 - 3:03
    It's called the Beijing
    Genomics Institute.
  • 3:04 - 3:07
    The Chinese are absolutely winning
    this race to the new Moon, by the way.
  • 3:07 - 3:09
    What does this mean for medicine?
  • 3:10 - 3:12
    So a woman, age 37,
  • 3:13 - 3:16
    presents with stage 2 estrogen
    receptor-positive breast cancer.
  • 3:16 - 3:19
    She is treated with surgery,
    chemotherapy and radiation.
  • 3:19 - 3:20
    She goes home.
  • 3:20 - 3:21
    Two years later,
  • 3:21 - 3:25
    she comes back with stage 3C
    ovarian cancer, unfortunately;
  • 3:25 - 3:28
    treated again with surgery
    and chemotherapy.
  • 3:28 - 3:30
    She comes back three years later at age 42
  • 3:30 - 3:33
    with more ovarian cancer,
    more chemotherapy.
  • 3:33 - 3:34
    Six months later,
  • 3:34 - 3:38
    she comes back
    with acute myeloid leukemia.
  • 3:39 - 3:42
    She goes into respiratory failure
    and dies eight days later.
  • 3:42 - 3:44
    So first: the way in which
    this woman was treated,
  • 3:44 - 3:48
    in as little as 10 years,
    will look like bloodletting.
  • 3:48 - 3:50
    And it's because of people
    like my colleague, Rick Wilson,
  • 3:50 - 3:53
    at the Genome Institute
    at Washington University,
  • 3:53 - 3:55
    who decided to take a look
    at this woman postmortem.
  • 3:55 - 3:58
    And he took skin cells, healthy skin
  • 3:58 - 4:00
    and cancerous bone marrow,
  • 4:01 - 4:03
    and sequenced the whole
    genomes of both of them
  • 4:03 - 4:05
    in a couple of weeks, no big deal.
  • 4:05 - 4:07
    Then he compared those two
    genomes in software,
  • 4:07 - 4:09
    and what he found, among other things,
  • 4:09 - 4:14
    was a deletion -- a 2,000-base deletion
    across three billion bases
  • 4:14 - 4:16
    in a particular gene called TP53.
  • 4:16 - 4:19
    If you have this deleterious
    mutation in this gene,
  • 4:19 - 4:21
    you're 90 percent likely
    to get cancer in your life.
  • 4:21 - 4:24
    So unfortunately,
    this doesn't help this woman,
  • 4:24 - 4:26
    but it does have severe --
    profound, if you will --
  • 4:26 - 4:28
    implications to her family.
  • 4:29 - 4:31
    I mean, if they have the same mutation,
  • 4:31 - 4:33
    and they get this genetic test
    and they understand it,
  • 4:33 - 4:36
    then they can get regular screens
    and can catch cancer early,
  • 4:36 - 4:39
    and potentially live
    a significantly longer life.
  • 4:39 - 4:41
    Let me introduce you to the Beery twins,
  • 4:41 - 4:43
    diagnosed with cerebral palsy
    at the age of two.
  • 4:43 - 4:46
    Their mom is a very brave woman
    who didn't believe it;
  • 4:46 - 4:47
    the symptoms weren't matching up.
  • 4:47 - 4:50
    And through some heroic efforts
    and a lot of Internet searching,
  • 4:50 - 4:52
    she was able to convince
    the medical community
  • 4:52 - 4:54
    that, in fact, they had something else.
  • 4:54 - 4:57
    They had dopa-responsive dystonia.
  • 4:57 - 4:59
    And so they were given L-Dopa,
  • 4:59 - 5:01
    and their symptoms did improve,
  • 5:01 - 5:03
    but they weren't totally asymptomatic.
  • 5:03 - 5:04
    Significant problems remained.
  • 5:04 - 5:07
    Turns out the gentleman in this picture
    is a guy named Joe Beery,
  • 5:07 - 5:09
    who was lucky enough to be the CIO
  • 5:09 - 5:11
    of a company called Life Technologies.
  • 5:11 - 5:13
    They're one of two companies
  • 5:13 - 5:16
    that makes these massive
    whole-genome sequencing tools.
  • 5:16 - 5:19
    And so he got his kids sequenced.
  • 5:19 - 5:22
    What they found was a series of mutations
    in a gene called SPR,
  • 5:22 - 5:25
    which is responsible for producing
    serotonin, among other things.
  • 5:25 - 5:29
    So on top of L-Dopa, they gave
    these kids a serotonin precursor drug,
  • 5:29 - 5:31
    and they're effectively normal now.
  • 5:31 - 5:34
    Guys, this would never have happened
    without whole-genome sequencing.
  • 5:34 - 5:37
    At the time -- this was
    a few years ago -- it cost $100,000.
  • 5:37 - 5:39
    Today it's $10,000, next year, $1,000,
  • 5:39 - 5:41
    the year after, $100, give or take a year.
  • 5:41 - 5:42
    That's how fast this is moving.
  • 5:42 - 5:44
    So here's little Nick --
  • 5:44 - 5:46
    likes Batman and squirt guns.
  • 5:46 - 5:50
    And it turns out Nick
    shows up at the children's hospital
  • 5:50 - 5:52
    with this distended belly,
    like a famine victim.
  • 5:52 - 5:55
    And it's not that he's not eating;
    it's that when he eats,
  • 5:55 - 5:58
    his intestine basically opens up
    and feces spill out into his gut.
  • 5:58 - 6:00
    So a hundred surgeries later,
  • 6:00 - 6:04
    he looks at his mom and says,
    "Mom, please pray for me.
  • 6:04 - 6:05
    I'm in so much pain."
  • 6:05 - 6:08
    His pediatrician happens to have
    a background in clinical genetics
  • 6:08 - 6:10
    and he has no idea what's going on,
  • 6:10 - 6:13
    but he says, "Let's get
    this kid's genome sequenced."
  • 6:13 - 6:15
    And what they find
    is a single-point mutation
  • 6:15 - 6:18
    in a gene responsible for controlling
    programmed cell death.
  • 6:18 - 6:21
    So the theory is that he's having
    some immunological reaction
  • 6:21 - 6:23
    to what's going on --
    to the food, essentially.
  • 6:23 - 6:27
    And that's a natural reaction,
    which causes some programmed cell death,
  • 6:27 - 6:29
    but the gene that regulates
    that down is broken.
  • 6:29 - 6:31
    And so this informs,
    among other things, of course,
  • 6:31 - 6:34
    a treatment for bone marrow transplant,
    which he undertakes.
  • 6:34 - 6:36
    And after nine months
    of grueling recovery,
  • 6:37 - 6:38
    he's now eating steak with A1 sauce.
  • 6:38 - 6:40
    (Laughter)
  • 6:40 - 6:44
    The prospect of using the genome
    as a universal diagnostic
  • 6:44 - 6:46
    is upon us today.
  • 6:47 - 6:48
    Today. It's here.
  • 6:48 - 6:50
    And what it means for all of us
  • 6:50 - 6:53
    is that everybody in this room
    could live an extra 5, 10, 20 years,
  • 6:53 - 6:55
    just because of this one thing.
  • 6:55 - 6:57
    Which is a fantastic story,
  • 6:57 - 7:00
    unless you think about
    humanity's footprint on the planet,
  • 7:00 - 7:02
    and our ability to keep up
    food production.
  • 7:02 - 7:04
    So it turns out
  • 7:04 - 7:08
    that the very same technology
    is also being used to grow new lines
  • 7:08 - 7:11
    of corn, wheat, soybean and other crops
  • 7:11 - 7:13
    that are highly tolerant
    of drought, of flood,
  • 7:13 - 7:15
    of pests and pesticides.
  • 7:15 - 7:16
    Now, look --
  • 7:16 - 7:19
    as long as we continue
    to increase the population,
  • 7:19 - 7:22
    we'll have to continue to grow and eat
    genetically modified foods.
  • 7:22 - 7:24
    And that's the only position
    I'll take today.
  • 7:24 - 7:26
    Unless there's anybody in the audience
  • 7:26 - 7:28
    who'd like to volunteer to stop eating?
  • 7:28 - 7:30
    None, not one.
  • 7:30 - 7:31
    This is a typewriter,
  • 7:32 - 7:35
    a staple of every desktop for decades.
  • 7:35 - 7:38
    And, in fact, the typewriter
    was essentially deleted by this thing.
  • 7:39 - 7:42
    And then more general versions
    of word processors came about.
  • 7:43 - 7:46
    But ultimately, it was a disruption
    on top of a disruption.
  • 7:46 - 7:48
    It was Bob Metcalfe
    inventing the Ethernet,
  • 7:48 - 7:50
    and the connection of all these computers
  • 7:50 - 7:52
    that fundamentally changed everything.
  • 7:52 - 7:54
    Suddenly we had Netscape, we had Yahoo.
  • 7:55 - 7:57
    And we had, indeed,
    the entire dot-com bubble.
  • 7:58 - 8:00
    (Laughter)
  • 8:01 - 8:03
    Not to worry though,
  • 8:03 - 8:05
    that was quickly rescued
    by the iPod, Facebook
  • 8:05 - 8:08
    and, indeed, Angry Birds.
  • 8:08 - 8:10
    (Laughter)
  • 8:10 - 8:13
    Look, this is where we are today.
  • 8:13 - 8:16
    This is the genomic revolution today.
    This is where we are.
  • 8:17 - 8:19
    What I'd like you to consider is:
  • 8:19 - 8:20
    What does it mean
  • 8:20 - 8:23
    when these dots don't represent
    the individual bases of your genome,
  • 8:23 - 8:26
    but they connect to genomes
    all across the planet?
  • 8:26 - 8:30
    I just recently had to buy life insurance,
    and I was required to answer:
  • 8:30 - 8:32
    A. I have never had a genetic test;
  • 8:32 - 8:34
    B. I've had one, here you go;
  • 8:34 - 8:36
    or C. I've had one and I'm not telling.
  • 8:36 - 8:37
    Thankfully, I was able to answer A,
  • 8:37 - 8:41
    and I say that honestly, in case
    my life insurance agent is listening.
  • 8:41 - 8:43
    But what would have happened
    if I had said C?
  • 8:43 - 8:46
    Consumer applications
    for genomics will flourish.
  • 8:46 - 8:48
    Do you want to see
    if you're genetically compatible
  • 8:48 - 8:49
    with your girlfriend?
  • 8:49 - 8:52
    DNA sequencing on your iPhone?
    There's an app for that.
  • 8:52 - 8:54
    (Laughter)
  • 8:54 - 8:57
    Personalized genomic massage, anyone?
  • 8:58 - 9:02
    There's already a lab today that tests
    for allele 334 of the AVPR1 gene,
  • 9:02 - 9:04
    the so-called cheating gene.
  • 9:04 - 9:06
    (Laughter)
  • 9:06 - 9:09
    So anybody who's here today
    with your significant other,
  • 9:09 - 9:12
    just turn over to them,
    swab their mouth, send it to the lab
  • 9:12 - 9:13
    and you'll know for sure.
  • 9:13 - 9:14
    (Laughter)
  • 9:14 - 9:17
    Do you really want to elect a president
  • 9:17 - 9:19
    whose genome suggests cardiomyopathy?
  • 9:19 - 9:21
    Think of it -- it's 2016,
  • 9:21 - 9:23
    and the leading candidate releases
  • 9:23 - 9:25
    not only her four years
    of back-tax returns,
  • 9:25 - 9:26
    but also her personal genome.
  • 9:26 - 9:28
    And it looks really good.
  • 9:28 - 9:30
    Then she challenges all
    her competitors to do the same.
  • 9:30 - 9:32
    Do you think that's not going to happen?
  • 9:32 - 9:34
    Do you think it would have
    helped John McCain?
  • 9:34 - 9:36
    (Laughter)
  • 9:36 - 9:39
    How many people in the audience
    have the last name Resnick, like me?
  • 9:39 - 9:41
    Raise your hand.
  • 9:41 - 9:42
    Anybody? Nobody.
  • 9:42 - 9:44
    Typically, there's one or two.
  • 9:44 - 9:46
    So my father's father
    was one of 10 Resnick brothers.
  • 9:46 - 9:50
    They all hated each other, and all moved
    to different parts of the planet.
  • 9:50 - 9:53
    So it's likely I'm related
    to every Resnick that I ever meet,
  • 9:53 - 9:55
    but I don't know.
  • 9:55 - 9:58
    So imagine if my genome
    were De-identified, sitting in software,
  • 9:58 - 10:00
    And a third cousin's genome
    was also sitting there,
  • 10:00 - 10:02
    and there was software
    that could compare the two
  • 10:02 - 10:04
    and make these associations.
  • 10:04 - 10:07
    Not hard to imagine. My company
    has software that does this right now.
  • 10:07 - 10:08
    Imagine one more thing,
  • 10:08 - 10:11
    that that software is able to ask
    both parties for mutual consent:
  • 10:12 - 10:14
    "Would you be willing
    to meet your third cousin?"
  • 10:14 - 10:16
    And if we both say yes -- voilà!
  • 10:16 - 10:17
    Welcome to Chromosomally LinkedIn.
  • 10:17 - 10:21
    (Laughter)
  • 10:22 - 10:24
    Now this is probably a good thing, right?
  • 10:24 - 10:25
    Bigger clan gatherings and so on.
  • 10:25 - 10:27
    But maybe it's a bad thing as well.
  • 10:27 - 10:29
    How many fathers in the room?
    Raise your hands.
  • 10:29 - 10:33
    OK, so experts think
    that one to three percent of you
  • 10:33 - 10:35
    are not actually the father of your child.
  • 10:35 - 10:37
    (Laughter)
  • 10:37 - 10:38
    Look --
  • 10:38 - 10:42
    (Laughter)
  • 10:43 - 10:45
    These genomes, these 23 chromosomes,
  • 10:45 - 10:49
    they don't in any way represent
    the quality of our relationships
  • 10:49 - 10:52
    or the nature of our society --
    at least not yet.
  • 10:52 - 10:54
    And like any new technology,
  • 10:54 - 10:55
    it's really in humanity's hands
  • 10:55 - 10:58
    to wield it for the betterment of mankind
  • 10:58 - 10:59
    or not.
  • 10:59 - 11:01
    And so I urge you all
    to wake up and to tune in
  • 11:01 - 11:04
    and to influence the genomic revolution
    that's happening all around you.
  • 11:04 - 11:06
    Thank you.
  • 11:06 - 11:07
    (Applause)
