Mining for gene-environment and gene-gene interactions: parametric and non-parametric tests for detecting variance quantitative trait loci [PDF]

Frontiers in Genetics
IntroductionDetection of variance quantitative trait loci (vQTL) can facilitate the discovery of gene-environment (GxE) and gene-gene interactions (GxG). Identifying vQTLs before direct GxE and GxG analyses can considerably reduce the number of tests and
