Characterization of Conditional eQTL (A) Counts of the numbers of genes (y axis) regulated by at least N (1 ≤ N ≤ 16) independent eQTL (x axis). (B) Median Tau value (y axis) for genes with N independent eQTL (x axis), colored by Tau type (cell type, developmental time point, or tissue type Tau). (C) Density plot representing the distance from eSNP to eGene transcription start site (TSS), colored by eQTL order. Dashed lines represent the median distance to TSS for each order of eQTL.
