JASS allows for single SNP joint analysis of multiple GWAS summary statistics. Our database currently includes ~150 publicly available GWAS (see next page for the complete list). Three tests have been implemented:
For the moment being, the application is in its early state. E.g., only the omnibus version of the joint analysis is implemented and can be applied on only 64 phenotypes.

Jass is developed by the Statistical Genetics group in collaboration with the HUB
