Fig. 1.

An example case of splicing-QTL. The gene has 3 isoforms. The splicing ratios of the three isoforms of the same sample are shown as points of different colors linked by a dashed line. Samples with the same genotype are shown together. We can see that the distribution patterns of splicing ratios are different between different genotypes, which indicates that this variant is associated with the alternative splicing pattern of this gene, and therefore it is a sQTL of the gene
