eQTL epistasis – challenges and computational approaches

The determination of eQTL epistasis - a form of functional interaction between genetic loci that affect gene expression - is an important step towards the thorough understanding of gene regulation. Since gene expression has emerged as an intermediate molecular phenotype eQTL epistasis might help to...
