Allele-specific expression reveals interactions between genetic variation and environment

The EAGLE algorithm and software identifies replicable gene-by-environment interactions based on associations between environment and allele-specific expression. Identifying interactions between genetics and the environment (GxE) remains challenging. We have developed EAGLE, a hierarchical Bayesian...

Zusammenfassung:The EAGLE algorithm and software identifies replicable gene-by-environment interactions based on associations between environment and allele-specific expression. Identifying interactions between genetics and the environment (GxE) remains challenging. We have developed EAGLE, a hierarchical Bayesian model for identifying GxE interactions based on associations between environmental variables and allele-specific expression. Combining whole-blood RNA-seq with extensive environmental annotations collected from 922 human individuals, we identified 35 GxE interactions, compared with only four using standard GxE interaction testing. EAGLE provides new opportunities for researchers to identify GxE interactions using functional genomic data.
