However these assays often fail to measure the genetic interactions among up to 40 of the studied gene pairs. Here we present a novel method which combines genetic interaction data together with diverse genomic data to quantitatively impute these missing interactions. We also present data on almost l90 000 novel interactions. Background Understanding the interactions between genes and proteins is essential for elucidating their function. Genetic interactions GIs describe the phenotype of a double knock-out in comparison to the phenotypes of single mutants and they can be crudely classified into positive alleviating neutral and negative aggravating interactions 1 2 . In a negative GI the fitness .
