CCMG Meeting September 2015
Agenda
1. COGR overview
2. Updates
3. Current variant numbers
4. BRCA Manuscript
4. Discussion
COGR Objectives
• To create Canada’s unified, open-access, clinical-grade genetic database
using a commonly shared platform
• Collaborative effort for the collection, sharing and analysis of variants
reported by medical diagnostic laboratories across Canada
• To create variant classification consensus among clinical laboratories
through data sharing and analysis
• To standardized variant assessment procedures and disseminate results
to a large public data repository
Workflow Overview
Update: Routine Variant Uploads
• Goal: Quarterly with discrepancy reports
• Now have additional informatics support
• Semi-automate export pre-processing
• Alamut export = Instantaneous upload
• Other = Customize script
Update: Variant Assessment Tool 5.0
• Release coming soon!
• What’s new
• Restructured with improved organization
• Now can directly import and export VAT from GeneInsight
Update: Public facing website
• Coming Winter of 2016!
• Open access resource for general audience
• Patients and family members at risk
• Portal to query diseases and associated genes linked to diseases
• Current variant classification
• Consensus
Update: Funding
• 3-year OGI grant is expiring
• Received additional funding to secure year 4 of COGR
• Applied for funding to link COGR with other collaborative
efforts such as the Global Alliance for Genomics and Heath
(GA4GH)

June 2015 Consensus Call
• Overall discrepant variant classifications did not change after
consensus call
• Proposal for moving forward:
1.
2.
Present collected evidence in ACMG guideline format
Ask discrepant lab(s) to review and re-assess variant classification
• Goal:
• Gather agreement that evidence based from ACMG guidelines is correct
• Suggestions?
BRCA Manuscript
• BRCA variant collaboration as an example of the power of data
sharing in Canada
• Currently have interest from Alberta, British Columbia, Manitoba
Ontario and Quebec
• BRCA1/2 variant data submission deadline is September 14th!
• Discrepancy report will be sent out at the end of September 2015
