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