sQTL mapping and assessment. a Scater plot showing the number of sQTLs. The x-axis and y-axis indicate the physical position of the lead SNP of the sQTL and its associated splice junction, respectively. Each dot represents a sQTL. Dots on the diagonal line indicate intrachromosomal associations. b Pie chart of cis- and trans-sQTLs. c Pie chart of IR-coupled genes with cis- and/or trans-sQTLs. d Histogramm of the sQTLs identified for each IR-coupled gene. The x-axis and y-axis represent the number of sQTLs identified for each gene and the number of genes in each group, respectively. e The density distribution of cis-sQTLs along the span between associated cis-SNP and IR splicing sites. f Significances of cis-sQTLs and trans-sQTLs. For boxplots, the lower and upper horizon lines are the minimum and maximum values of − log10 (p), respectively; the boxes span from the first to third quartiles; and the center line indicates the second quartile (median)
