Why genetic research must be more diverse

  • 0:01 - 0:02
    As a little Hawaiian,
  • 0:02 - 0:05
    my mom and auntie always told me
    stories about Kalaupapa --
  • 0:06 - 0:07
    the Hawaiian leper colony
  • 0:07 - 0:10
    surrounded by the highest
    sea cliffs in the world --
  • 0:10 - 0:11
    and Father Damien,
  • 0:11 - 0:15
    the Belgian missionary who gave his life
    for the Hawaiian community.
  • 0:15 - 0:16
    As a young nurse,
  • 0:16 - 0:19
    my aunt trained the nuns
    caring for the remaining lepers
  • 0:19 - 0:23
    almost a 100 years after
    Father Damien died of leprosy.
  • 0:25 - 0:26
    I remember stories she told
  • 0:26 - 0:29
    about traveling down
    switchback cliff paths on a mule,
  • 0:29 - 0:32
    while my uncle played
    her favorite hula songs on the ukulele
  • 0:32 - 0:34
    all the way down to Kalaupapa.
  • 0:35 - 0:36
    You see, as a youngster,
  • 0:36 - 0:38
    I was always curious about a few things.
  • 0:39 - 0:44
    First was why a Belgian missionary
    chose to live in complete isolation
  • 0:44 - 0:45
    in Kalaupapa,
  • 0:45 - 0:47
    knowing he would inevitably
    contract leprosy
  • 0:47 - 0:50
    from the community of people
    he sought to help.
  • 0:50 - 0:53
    And secondly,
  • 0:53 - 0:55
    where did the leprosy bacteria come from?
  • 0:55 - 0:57
    And why were Kānaka Maoli,
  • 0:57 - 0:59
    the indigenous people of Hawaii,
  • 0:59 - 1:03
    so susceptible to developing
    leprosy, or "Mai Pake"?
  • 1:04 - 1:08
    This got my curious about what
    makes us unique as Hawaiians --
  • 1:08 - 1:09
    namely, our genetic makeup.
  • 1:11 - 1:13
    But it wasn't until high school,
  • 1:13 - 1:15
    through the Human Genome Project,
  • 1:15 - 1:17
    that I realized I wasn't alone
  • 1:17 - 1:20
    in trying to connect
    our unique genetic ancestry
  • 1:20 - 1:23
    to our potential health,
    wellness and illness.
  • 1:24 - 1:25
    You see,
  • 1:25 - 1:27
    the 2.7 billion-dollar project
  • 1:27 - 1:31
    promised an era of predictive
    and preventative medicine
  • 1:31 - 1:33
    based on our unique genetic makeup.
  • 1:34 - 1:36
    So to me it always seemed obvious
  • 1:36 - 1:38
    that in order to achieve this dream,
  • 1:38 - 1:42
    we would need to sequence
    a diverse cohort of people
  • 1:42 - 1:46
    to obtain the full spectrum
    of human genetic variation on the planet.
  • 1:46 - 1:49
    That's why 10 years later,
  • 1:49 - 1:51
    it continues to shock me,
  • 1:51 - 1:54
    knowing that 96 percent of genome studies
  • 1:54 - 1:57
    associating common genetic variation
    with specific diseases
  • 1:57 - 2:01
    have focused exclusively
    on individuals of European ancestry.
  • 2:02 - 2:03
    Now you don't need a PhD
  • 2:04 - 2:07
    to see that that leaves four percent
    for the rest of diversity.
  • 2:07 - 2:09
    And in my own searching,
  • 2:09 - 2:12
    I've discovered that far less
    than one percent
  • 2:12 - 2:15
    have actually focused on indigenous
    communities, like myself.
  • 2:15 - 2:18
    So that begs the question:
  • 2:18 - 2:20
    who is the Human Genome
    Project actually for?
  • 2:21 - 2:23
    Just like we have
    different colored eyes and hair,
  • 2:23 - 2:25
    we metabolize drugs differently
  • 2:25 - 2:27
    based on the variation in our genomes.
  • 2:27 - 2:30
    So how many of you
    would be shocked to learn
  • 2:30 - 2:33
    that 95 percent of clinical trials
  • 2:33 - 2:38
    have also exclusively featured
    individuals of European ancestry?
  • 2:38 - 2:40
    This bias
  • 2:40 - 2:44
    and systematic lack of engagement
    of indigenous people,
  • 2:44 - 2:47
    in both clinical trials
    and genome studies,
  • 2:47 - 2:50
    is partially the result
    of a history of distrust.
  • 2:51 - 2:52
    For example,
  • 2:52 - 2:56
    in 1989, researchers
    from Arizona State University
  • 2:56 - 3:00
    obtained blood samples
    from Arizona's Havasupai tribe,
  • 3:00 - 3:03
    promising to alleviate the burden
    of type 2 diabetes
  • 3:03 - 3:04
    that was plaguing their community,
  • 3:04 - 3:08
    only to turn around and use
    those exact same samples --
  • 3:08 - 3:10
    without the Havasupai's consent --
  • 3:10 - 3:14
    to study rates
    of schizophrenia, inbreeding,
  • 3:14 - 3:17
    and challenge
    the Havasupai's origin story.
  • 3:17 - 3:20
    When the Havasupai found out,
  • 3:20 - 3:23
    they sued successfully for $700,000,
  • 3:23 - 3:28
    and they banned ASU from conducting
    research on their reservation.
  • 3:29 - 3:32
    This culminated in a sort of domino effect
  • 3:32 - 3:34
    with local tribes in the Southwest --
  • 3:34 - 3:35
    including the Navajo Nation --
  • 3:35 - 3:38
    one of the largest
    tribes in the country --
  • 3:38 - 3:40
    putting a moratorium on genetic research.
  • 3:40 - 3:43
    Now despite this history of distrust,
  • 3:43 - 3:47
    I still believe that indigenous people
    can benefit from genetic research.
  • 3:47 - 3:50
    And if we don't do something soon,
  • 3:50 - 3:52
    the gap in health disparities
    is going to continue to widen.
  • 3:53 - 3:55
    Hawaii, for example,
  • 3:55 - 3:58
    has the longest life expectancy
    on average of any state in the US,
  • 3:58 - 4:01
    yet native Hawaiians like myself
  • 4:01 - 4:04
    die a full decade
    before our non-native counterparts,
  • 4:04 - 4:08
    because we have some
    of the highest rates of type 2 diabetes,
  • 4:08 - 4:09
    obesity,
  • 4:10 - 4:12
    and the number one and number
    two killers in the US:
  • 4:12 - 4:14
    cardiovascular disease and cancer.
  • 4:14 - 4:16
    So how do we ensure
  • 4:16 - 4:19
    the populations of people
    that need genome sequencing the most
  • 4:19 - 4:20
    are not the last to benefit?
  • 4:21 - 4:25
    My vision is to make
    genetic research more native,
  • 4:25 - 4:28
    to indigenize genome
    sequencing technology.
  • 4:29 - 4:32
    Traditionally, genomes
    are sequenced in laboratories.
  • 4:33 - 4:35
    Here's an image of your classic
    genome sequencer.
  • 4:35 - 4:36
    It's huge.
  • 4:36 - 4:38
    It's the size of a refrigerator.
  • 4:39 - 4:41
    There's this obvious physical limitation.
  • 4:41 - 4:44
    But what if you could sequence
    genomes on the fly?
  • 4:45 - 4:49
    What if you could fit a genome
    sequencer in your pocket?
  • 4:52 - 4:54
    This nanopore-based sequencer
  • 4:54 - 4:59
    is one 10,000th the size
    of your traditional genome sequencer.
  • 4:59 - 5:01
    It doesn't have the same
    physical limitations,
  • 5:01 - 5:05
    in that it's not tethered to a lab bench
    with extraneous cords,
  • 5:05 - 5:08
    large vats of chemicals,
    or computer monitors.
  • 5:08 - 5:14
    It allows us to de-black box genome
    sequencing technology development
  • 5:14 - 5:16
    in way that's immersive and collaborative,
  • 5:16 - 5:19
    activating and empowering
    indigenous communities ...
  • 5:20 - 5:22
    as citizen scientists.
  • 5:23 - 5:26
    100 years later in Kalaupapa,
  • 5:26 - 5:30
    we now have the technology to sequence
    leprosy bacteria in real time,
  • 5:30 - 5:33
    using mobile genome sequencers,
  • 5:33 - 5:36
    remote access to the Internet
  • 5:36 - 5:37
    and cloud computation.
  • 5:38 - 5:41
    But only if that's what
    Hawaiian people want.
  • 5:42 - 5:43
    In our space,
  • 5:43 - 5:45
    on our terms.
  • 5:46 - 5:52
    IndiGenomics is about science
    for the people by the people.
  • 5:52 - 5:56
    We'll be starting with a tribal
    consultation resource,
  • 5:56 - 5:59
    focused on educating
    indigenous communities
  • 5:59 - 6:02
    on the potential use and misuse
    of genetic information.
  • 6:03 - 6:06
    Eventually we'd like to have our own
    IndiGenomics research institute
  • 6:06 - 6:08
    to conduct our own experiments
  • 6:08 - 6:11
    and educate the next generation
    of indigenous scientists.
  • 6:12 - 6:13
    In the end,
  • 6:13 - 6:18
    indigenous people need to be partners in
    and not subjects of genetic research.
  • 6:18 - 6:20
    And for those on the outside,
  • 6:20 - 6:22
    just as Father Damien did,
  • 6:23 - 6:27
    the research community needs
    to immerse itself in indigenous culture
  • 6:27 - 6:29
    or die trying.
  • 6:29 - 6:30
    Mahalo.
  • 6:30 - 6:35
