Feb 8, 2012
Outline
 Part 1: Filtering out SNPs found in genomes of healthy individuals
 Uploading files
 Using Galaxy libraries
 Basic filtering
 Part 2: Selecting known coding SNPs predicted to be damaging, then finding their genes
and associated pathways
 PolyPhen2
 Gene-based analysis
 Part 3: Running new predictions for coding SNPs likely to be detrimental
 SIFT
 Workflows
 Part 4: Finding SNPs that fall in any given set of intervals
 Predicted regulatory regions, ENCODE functional data, phyloP conserved regions
Fake example dataset
 SNP calls from Complete Genomics GS12880
 5 known disease variants added for illustration
 Various genes and parts of the gene (coding, regulatory, splicing, …)
 Realistic background for search, but not a realistic SNP combination
