Take home messages
• DNA sequencing = exciting new opportunities
+ new challenges
• Your genome is your data (like your EHR)
• Options for sharing today are limited mostly to
all-or-nothing
• Take the opportunity to voice your opinion
My aim with this talk: to give you a little view of how you can share genetic data today, and give
you an idea of the challenges involved.
I will end the presentation with a brief introduction to the DNAdigest project, and then open the
floor for questions and discussion.
Data is donated to research
Individuals are offered to opt-in their consent for their
data to be used for research to aid development of
diagnostics and treatments for genetic diseases

Genetic data is needed for research into inborn illnesses, heriditary diseases, rare diseases and cancer.
Genome research today
the patient
the researcher
the sample
the data

DNAdigest.org
Direct-to-consumer
genetic testing
You can order your own personal genotyping kit online
for only $99 from http://23andme.com
You can assess your own carrier status for known
disease genes before you get pregnant, for example
https://www.counsyl.com/
You can obtain non-invasive pre-natal testing by
detecting foetus DNA in the mothers blood, example
http://www.verinata.com/
You can have your whole genome sequenced for about
$7,000 http://www.dnadtc.com/products.aspx
Example: 23andme
Manuel Corpas used direct-to-consumer testing
for himself and his family
The “Corpasome”

Metagenomics
The “Corpasome”
Family genome and analysis published open
access online

open access online as a free resource for research
But what about privacy?
There is large variation between individuals,
and we are all unique
This means that your genome
sequence can identify you
- or your heritage
Similarly, your medical record
may contain information that is
unique to you

DNAdigest.org

3,000,000,000bp ~ 3billion basepairs
in the human genome
Consent for research
The head of the research
project will create a
custom consent form:
- Purpose
- How, when and who

DNAdigest.org
Consent forms vary
Guidelines from NHS on informed consent:

http://www.hra.nhs.uk/documents/2013/09/information-sheet-and-consent-form-guidance.pdf
DNAdigest.org
Consent forms vary
Guidelines from NHS on privacy:
Example wordings

http://www.hra.nhs.uk/documents/2013/09/information-sheet-and-consent-form-guidance.pdf
DNAdigest.org
Consent is obtained in the
interest of the patient
However,
Contact with patient may be lost after data
collection
The institution acts as the custodian of the
collected data,
and data is locked up
Institutions do not freely share data because revealing
entire datasets breaches confidentiality

Data access is restricted if available at all
If available, access requires specific application per dataset per project
Results are published
When sufficient data is collected for a project, an
analysis is made and a paper may be published
to report the results.

Results from confidential data are reported in
anonymized form
Anonymization = removal of identifiers
• Name, birthdate, NHS number, town of birth
Published information
Level of data detail varies per project and per
publication.
Rare disease research usually includes family
pedigrees and detailed description of the
disease symptoms per individual
GWAS studies usually
include only aggregated
statistics
Problem for data sharing
Trade-off: details are necessary for data re-use!
Restricted access
repositories

Completely public data

•

•
•

•
•

Advantage: access to
complete datasets of
genetics and medical
data
Disadvantage:
cumbersome,
timeconsuming and
slow processing of
application for access
Disadvantage:
difficult to discover the
data you need

•
•

Advantage: Easy
access
Disadvantage: if
medical data is
removed = no value for
research
Disadvantage: no
guarantee of privacy
Example: The Personal
Genomes Project
Limitations of current mechanisms
• Not easy to discover data
• Not easy to apply for access to data
• Not easy to deal with bulk datasets
As a consequence:
•
•
•
•

Researchers do not cross-check their results
Data is not re-used for analysis
Researchers duplicate existing work
Results are published based on small sample sizes

DNAdigest.org
What if?
•
•
•
•

Every individuals would be custodian of their own data?
What if there would be different ways of sharing data?
What if you could share just part of your data?
What if the consent form included options for the level
of sharing of the data?
• What if you gave patients the option to share their data
with no restrictions?
• What if you could share data in aggregate statistics?
• What if you could share your data today and change your
mind tomorrow?
DNAdigest.org
New approaches

• Crowdsourcing of genetic testing results:
#freethedata for breast cancer genes BRCA1 and BRCA2

• Share your 23andme data with OpenSNP
• Control your EHR with PatientsKnowBest
• DNAdigest: Allow sharing of aggregated data to
enable discovery and faster access for research
DNAdigest.org
Our mission
To create a self sustainable platform that supports the
widest possible sharing and access of genomic data in
accordance with patient consent.
DNAdigest is designing an ethical
data sharing platform

Allowing hypothesis centered queries, returning
anonymised aggregated data by patented mechanism
Results are delivered as
anonymised aggregated statistics

Open research cambridge December 16 2013 - presentation by Fiona Nielsen DNAdigest

  • 1. Secure the data – share the knowledge DNAdigest.org Open Research Cambridge Fiona Nielsen, December 16, 2013
  • 2. Take home messages • DNA sequencing = exciting new opportunities + new challenges • Your genome is your data (like your EHR) • Options for sharing today are limited mostly to all-or-nothing • Take the opportunity to voice your opinion My aim with this talk: to give you a little view of how you can share genetic data today, and give you an idea of the challenges involved. I will end the presentation with a brief introduction to the DNAdigest project, and then open the floor for questions and discussion.
  • 3. Data is donated to research Individuals are offered to opt-in their consent for their data to be used for research to aid development of diagnostics and treatments for genetic diseases Genetic data is needed for research into inborn illnesses, heriditary diseases, rare diseases and cancer.
  • 4. Genome research today the patient the researcher the sample the data DNAdigest.org
  • 5. Direct-to-consumer genetic testing You can order your own personal genotyping kit online for only $99 from http://23andme.com You can assess your own carrier status for known disease genes before you get pregnant, for example https://www.counsyl.com/ You can obtain non-invasive pre-natal testing by detecting foetus DNA in the mothers blood, example http://www.verinata.com/ You can have your whole genome sequenced for about $7,000 http://www.dnadtc.com/products.aspx
  • 6. Example: 23andme Manuel Corpas used direct-to-consumer testing for himself and his family
  • 7. The “Corpasome” Family genome and analysis published open access online • • • Deceased 1M 23andMe • v3 SNP chip • • • • • • • Age: 75 1M 23andMe v3 SNP chip 15,823,554 HiSeq Exome PE Reads Age: 51 1M 23andMe v3 SNP chip 14,123,580 HiSeq Exome PE Reads • • • • Age: 79 1M 23andMe v3 SNP chip 15,190,489 HiSeq Exome PE Reads Age: 36 0.5M 23andMe v2 SNP chip 32,116,828 HiSeq Exome SE Reads Metagenomics
  • 8. The “Corpasome” Family genome and analysis published open access online open access online as a free resource for research
  • 9. But what about privacy? There is large variation between individuals, and we are all unique This means that your genome sequence can identify you - or your heritage Similarly, your medical record may contain information that is unique to you DNAdigest.org 3,000,000,000bp ~ 3billion basepairs in the human genome
  • 10. Consent for research The head of the research project will create a custom consent form: - Purpose - How, when and who DNAdigest.org
  • 11. Consent forms vary Guidelines from NHS on informed consent: http://www.hra.nhs.uk/documents/2013/09/information-sheet-and-consent-form-guidance.pdf DNAdigest.org
  • 12. Consent forms vary Guidelines from NHS on privacy: Example wordings http://www.hra.nhs.uk/documents/2013/09/information-sheet-and-consent-form-guidance.pdf DNAdigest.org
  • 13. Consent is obtained in the interest of the patient However, Contact with patient may be lost after data collection The institution acts as the custodian of the collected data,
  • 14. and data is locked up Institutions do not freely share data because revealing entire datasets breaches confidentiality Data access is restricted if available at all If available, access requires specific application per dataset per project
  • 15. Results are published When sufficient data is collected for a project, an analysis is made and a paper may be published to report the results. Results from confidential data are reported in anonymized form Anonymization = removal of identifiers • Name, birthdate, NHS number, town of birth
  • 16. Published information Level of data detail varies per project and per publication. Rare disease research usually includes family pedigrees and detailed description of the disease symptoms per individual GWAS studies usually include only aggregated statistics
  • 17. Problem for data sharing Trade-off: details are necessary for data re-use! Restricted access repositories Completely public data • • • • • Advantage: access to complete datasets of genetics and medical data Disadvantage: cumbersome, timeconsuming and slow processing of application for access Disadvantage: difficult to discover the data you need • • Advantage: Easy access Disadvantage: if medical data is removed = no value for research Disadvantage: no guarantee of privacy Example: The Personal Genomes Project
  • 18. Limitations of current mechanisms • Not easy to discover data • Not easy to apply for access to data • Not easy to deal with bulk datasets As a consequence: • • • • Researchers do not cross-check their results Data is not re-used for analysis Researchers duplicate existing work Results are published based on small sample sizes DNAdigest.org
  • 19. What if? • • • • Every individuals would be custodian of their own data? What if there would be different ways of sharing data? What if you could share just part of your data? What if the consent form included options for the level of sharing of the data? • What if you gave patients the option to share their data with no restrictions? • What if you could share data in aggregate statistics? • What if you could share your data today and change your mind tomorrow? DNAdigest.org
  • 20. New approaches • Crowdsourcing of genetic testing results: #freethedata for breast cancer genes BRCA1 and BRCA2 • Share your 23andme data with OpenSNP • Control your EHR with PatientsKnowBest • DNAdigest: Allow sharing of aggregated data to enable discovery and faster access for research DNAdigest.org
  • 21. Our mission To create a self sustainable platform that supports the widest possible sharing and access of genomic data in accordance with patient consent.
  • 22. DNAdigest is designing an ethical data sharing platform Allowing hypothesis centered queries, returning anonymised aggregated data by patented mechanism
  • 23. Results are delivered as anonymised aggregated statistics DEMO
  • 24. Further reading • • • • • What to consider before undergoing a DNA test article in the Wall Street Journal Manuel Corpas blog: http://manuelcorpas.com Interview about the DNAdigest project on Open-Steps.org Genetic Privacy Network (launched Dec 2013) resources about the risks and legal issues for US residents Anonymization and re-identification: Routes for breaching and protecting genetic privacy by Erlich and Narayanan DNAdigest.org
  • 25. Take home messages • DNA sequencing = exciting new opportunities + new challenges • Your genome is your data (like your EHR) • Options for sharing today are limited mostly to all-or-nothing • Take the opportunity to voice your opinion • It is question time!
