  1. Genes detected by cTWAS at PIP > 0.9 in at least one of the tissues in the two tissue groups. The Max PIP Tissue, Max PIP and z-score columns denote the tissue with the highest PIP for each gene, its corresponding PIP and z score from TWAS in that tissue. The other tissue column lists any additional tissues with cTWAS PIP > 0.8. The evidence column denotes whether each gene is in the silver standard gene list (‘known’), the nearest gene to genome-wide significant GWAS peak for IBD (‘nearest’), or otherwise new (‘new’).
