Fig 2. Discovery and overlap of expression QTLs and variance QTLs.

(A) z-scores for expression QTL (eQTL) SNP-gene pairs discovered in pooled single cell RNA-seq data against z-scores of the same SNP-gene pairs in matched bulk RNA-seq data. (B) In the single cell data, z-scores for eQTL SNP-gene pairs (FDR 10%) against variance QTL (vQTL) z-scores of the same SNP-gene pairs. vQTL z-scores are stratified based on whether the gene was discovered as a vQTL at FDR 10%.
