Figure 7. Partial correlation analysis and modeling of genes with expression in the eye that are modulated by Tyrp1 or Myo5a in the heatmap. A: Summary table showing partial correlation coefficients and corresponding p values for all relationships. B: Composite model showing all Pearson correlation coefficients. Circular lines indicate cis-eQTLs. Linear lines indicate direct regulation of one gene by another. Edges that connect Myo5a directly to other genes/transcripts such as Tyr are labeled with the values of the partial correlation that removes the effects of variation in Tyrp1.
