Genome sharing projects across the world
Did you ever wonder what happened to the exponential increase in genome sequencing data? It is out there around the world and a lot of it is consented for research use. This means that if you just know where to find the data, you can potentially analyse gigabytes of data to power your research.
In this talk Fiona will present community genome initiatives, the genome sharing projects across the world, how you can benefit from this wealth of data in your work, and how you can boost your academic career by sharing and collaboration.
by Fiona Nielsen, Founder and CEO of DNAdigest and Repositive
With a background in software development Fiona pursued her career in bioinformatics research at Radboud University Nijmegen. Now a scientist-turned-entrepreneur Fiona founded DNAdigest and its social enterprise spin-out Repositive Ltd. Both the charity and company focus on efficient and ethical sharing of genetics data for research to accelerate diagnostics and cures for genetic diseases.

Genome sharing projects around the world nijmegen oct 29 - 2015
1. Genome sharing projects
around the world
– and how you find data for
your research
Fiona Nielsen, October 2015
Find me on twitter: @glyn_dk
2. • In case my talk will be boring…
First the take home messages…
3. Do not forget:
By 2025 genome research will produce as much data
as Twitter /YouTube.
You do not have
enough statistical
power to interpret
your data
But
You can
improve your
study design
And
You can access
more data from
public genome
data repositories
5. Data output is going up
2006 2007 2008 2009 2010 2011 2012 2013 2014 2015
400K
Genomes
Sequenced
The output of human genome
sequencing data is growing at
exponential rates
Estimated number of human
genomes sequenced in 2015
6. Population scale genome sequencing projects
Population scale genome
sequencing projects have
been launched all over
the world
Soon every research lab
and every genetic clinic
will have a DNA
sequencer
7. How much data do you need to publish a paper?
2001: 1 human genome
2012: 1000 Genomes (1092 genomes, since increased to ~2500)
2015:
UK10K, Icelandic population (2,636 + 100k imputed),
Cancer genome atlas ~11,000 genomes
Exac consortium 65,000 exomes
?
8. Statistically speaking, you still need 10s of thousands of samples for
validation
The more severe the phenotype and the more complete penetrance, the
easier it will be for you to find your variant, but
“As the genetic complexity of the disease increases (for example,
reduced penetrance and increased locus heterogeneity), issues of
statistical power quickly become paramount.”
http://www.nature.com/nrg/journal/v15/n5/full/nrg3706.html
But I am just looking at this one disease…
9. What can I do?
PRO TIP: involve a statistician early on in your study design!
10. How can I determine significance?
“One potentially powerful approach is to assess conservation across and within
multiple species as whole-genome sequence data become more abundant.”
Look at extreme phenotypes “Sampling cases or controls from the extremes of an
appropriate quantitative distribution can often increase power”
Look at non-SNP variants, they are more likely to have functional effects
- “how to account for the technical features of sequencing, such as incomplete
sequencing and biased coverage over the genome?”
11. Think of how you can provide evidence that your result is not just a local
technical variation or sampling bias
e.g. data from same cell type, same seq technology, same alignment…
How to account for bias?
PRO TIP: include more reference data in your analysis
12. • Know what data is available in your lab,
your dept, your org
• Survey from Qiagen showed that one of
the main reasons researchers collaborate
is to get access to data!
How can I access more data for my research?
13. How can I find collaborators?
PRO TIP: Search for collaborators who have the data you need
PRO TIP: Tell your colleagues and peers what type of data you
have in your lab
14. Where can I access data?
public repositories
• some you apply for access,
especially if data contains
clinical info or whole genome
PID
• some are open access: GEO,
SRA, PGP, OpenSNP, GigaDB, …
• some are consented for
general research use, some
have specific consent
16. And it takes time
Bottlenecks:
• Finding relevant and usable
data
• Getting authorisation to
access data
• Formatting data
• Storing and moving data
We studied the problem by
qualitative interviews followed
by a survey of researchers in
human genetics
17. And it takes time

data sharing: a focus on data
accessibility, Applied &
Translational Genomics, 2014
10.1016/j.atg.2014.09.013
Researchers spend months to
find and access genomic data,
and often choose to not access
data at all

20. Why the barrier?
• Benefits: strict governance, review of consent, applicant signs for full
responsibility for governance
• Disadvantages: No control of data once access is given, high barrier for
access – too high?
21. • Start planning your data needs early in your project
• When you find the data you need, start application
• Use Open Access data
How can I save time?
PRO Tip: If you use human genomic data, apply for the GRU
datasets in dbGaP, one application – access to all the GRU
datasets
22. • Some data is Open Access requires specific consent
• OpenSNP.org (Bastian)
• Personal Genomes Projects
• Individuals who put their genomes online, e.g. Manuel Corpas
and his family “the Corpasome”
• http://manuelcorpas.com/about/
Not all data is restricted

26. Where is the data?
2006 2007 2008 2009 2010 2011 2012 2013 2014 2015
≈ 5K
Genomes
Available
400K
Genomes
Sequenced
Only a fraction of the data is
findable or available through
public repositories
27. • “even when researchers are authorised to share data they
report reluctance to do so because of the amount of effort
required“ http://www.sciencedirect.com/science/article/pii/S2212066114000386
• “Clinical geneticists cited a lack of time because their main priority is
diagnosing patients. Industrial researchers cited a lack of time because of
the pressure to meet the deadlines in their job. Researchers in academia
cited both a concern about the potential loss of future publications once
unpublished data is shared, and the lack of time and incentive to share
data as this does not contribute to their publication record. Researchers
from all categories felt that they lacked sufficient resources to make their
data available.”
The barrier of making data available
But I do not want to share my data
28. • If you expect data to be available to you
– you have to make your data available too!
• Encourage collaborations: power by numbers
1. Get credit – publish and make your data available
2. Give credit – cite data sources
3. Understand consent – for all uses of clinical data
Best practices
29. • Use all available tools to make your life easier:
• Data publications visibility and citations for your data, e.g.
GigaScience
• Figshare, Zenodo, Dryad for sharing open access data
• PhenomeCentral, Matchmaker exchange for rare disease research
• Repositive for finding data across repositories and make your own data
discoverable
Best practices: use the tools
31. “Weakness: Involvement of non-
academic beneficiaries is limited”
“Weakness: highly focused on academic activities, and
lacks an advanced communication strategy”
“Weakness: limited exposure to
non-academic partners & infrastructures”
Excellence
Impact
Implementation
“data accessibility is unclear!”
“data storage & access not considered”
32. “Strengths: extensive dissemination of data to the
scientific community (open access, databases)”
“outreach activities to a broad audience”
“research software is freely available”
Impact:
33.
34. Make the (research) world a better place by sharing in return
Best practices
35. • Digital consent: towards automatic processing of applications
• Dynamic consent and power to the patient, e.g.
PatientsKnowBest
• Privacy-preserving access to datasets: preserving control and
governance with data custodian, lower barrier for access
What the future holds
36. In the meantime: It is a jungle out there!
What if finding data was as easy as finding a book on
Amazon, book a hotel on Expedia?

It has been shown that the combination of summary single-variant statistics from multiple data sets, rather than the joint analysis of a combined data set, does not result in an appreciable loss of information85, and that taking into account heterogeneity in effect size across studies can improve statistical power
“Although they are harder to call and annotate, insertion or deletions, multinucleotide variants and structural variants (including copy-number variants, translocations and inversions) constitute a smaller set of variation (in terms of the number of discrete events an individual is expected to carry) relative to all SNVs and are more likely to have functional effects.”

Because interpretation requires LOTS of data
And although data exists around the world, it is siloed, and even if available, it is not accessible
This is Jenn, a genetic researcher –our target customer- seeking to interpret data from genetic diseases and cancer
She needs data from other patients to compare and interpret Mabels DNA
She also has data available in her own lab, but she cannot share because of concerns how to deal with secure access to sensitive data and data governance, e.g. vetting of users
Public repositories: default is apply for access -> full access
Benefits: strict governance, review of consent, applicant signs for full responsibility for governance
Disadvantages: No control of data once access is given, high barrier for access – too high? (researchers giving up, even patients can’t get access to their own data)
Cost of data is going down
Data production is going up
Growing problem
Market opportunity for solutions!
ODP trained, EURO-BASIN manager, – a boring title, for a diverse job, in an exciting research domain.
DIP into EACH step of the research cycle, from proposal formulation to providing the best return-on-investment to the funders.
So I`d like to share with you some experiences from the last few years of OS advocacy in the Marine Science Community
Excellence at your Research Subject is … excellent, but is it ENOUGH ?
To be successful, a candidate will be judged on being complete.
MESSAGE: FOSUC only on IF could expose you to risk

So, if the IMPACT FACTOR is no good, how will it evolve in future?
Here is an example from the UK, on how Research Institutes are evaluated …
The key message here is that, in future, funders will place even more emphasis on ”Societal Impact” in future, but more pertinent for you right now and today is that it is already affecting your chances for Post-Doc funding.
For Jenn, the inaccessibility of data means it takes her up to 6 months to find and up to 6 months to access to the data she needs for analysis.
But for clinical cases like Mabel, she only has days to finish her analysis!
THIS IS RIDICULOUS BECAUSE:
Today one can:
- Find any hotel on Trivago
- Find any book on amazon – with feedback from other users
- But researchers have nowhere to find and acess (human) genomics data!
The Repositive platform and technology will remove barriers to data sharing and will incentivise users to explore, contribute and collaborate in alignment with best practices
When Jenn needs data for a specific disease she makes a search on Repositive to find the data directly, understand the value of the data based on feedback from the Repositive user community, access the data securely, because she knows that
…Repositive is the trusted broker for secure and efficient data exchange …
No more hassles of finding data or hassles of exchanging data with collaborators, [show dbGaP screenshots with a cross over it]
