Genetic basis of immune-mediated diseases

 

While an enormous number of genetic variants have been associated with risk for human disease, how these variants affect gene expression in various cell types remains largely unknown. To address this gap as it relates to immune cells, as well as to identify which immune cell types are most susceptible to the effects of disease-risk variants, the DICE (Database of Immune Cell Expression, Expression quantitative trait loci (eQTLs) and Epigenomics) project was established in 2014, led by my laboratory (https://dice-database.org/)
