Pathway Analysis Tool

ARTP2 (Adaptive Rank Truncated Product - Version 2) is an R package of biological pathway association analysis or pathway meta-analysis for genome-wide association studies (GWAS). It also provides tools for gene-level association test as a special case. ARTP2 is an enhanced version of two previously released packages ARTP and AdaJoint.

This online application was developed to assist epidemiological researchers for testing the association between complex disease/trait outcome and predefined pathways when only SNP-level summary statistics from one or multiple GWAS were available. We provide reference panel data incorporated from the 1000 Genomes Project to facilitate the studies on various populations. We also support over 4,700 pathways predefined by the BROAD Institute.
