The ability to measure molecular traits in biological systems has dramatically expanded in recent years, enabling the measurement of tens of thousands molecular phenotypes across thousands of individuals and multiple tissue types and associate those with millions of variants in the genome. Deriving actionable, biological interpretations from these datasets remains a challenging problem, and this Data Analytics challenge focuses on generating useful interpretations from large, populationwide, multi-tissue, molecular phenotyping assays. Specifically, the genes that predict tissue state will be identified, and genetic perturbations will be leveraged to characterize the genes that act in concert to orchestrate overt phenotypes.
