An example of an eQTL for gene LHX9 identified as statistically significant by our joint score test method. a Barplot displaying all the statistics computed for LHX9 gene and SNP rs10922303 from our joint test, TBT-meQTL, TBT-eQTL and JAGUAR methods. The vertical axis represent -log10 p values. b Interaction plot illustrating tissue-specific genotypic effect on gene expression. Given that the lines are nonparallel, there is an interaction effect between tissue type and genotype
