Pathway enrichment analysis of the genes regulated by chr17 was performed with GSEA 69 on the full list of genes ordered by effects size of association between gene expression with copy number and with a custom set of pathways. The custom set of pathways considered comprised 1,156 super pathways from the PathCards database 23 filtered to exclude pathways relating to infectious diseases and pharmacokinetics. Multiple testing correction was performed as described in 69.
