More recently, similar approaches have been applied to RNA sequencing (RNA-seq) data to find variants associated with expression level, called expression quantitative trait loci (eQTL). Recent advances in experimental techniques have provided an unprecedented opportunity to measure gene expression at the single cell level, and the chance to study cellular heterogeneity.
