We also observed that different eGenes could have shared upstream genes/pathways as we identified four common immune-related co-eGenes associated with rs393727–RNASET2 and rs1131017–RPS26, and both SNPs were in LD with immune diseases (T1D and CD), suggesting a shared upstream process for these two eQTL effects. The gene discussed is RNASET2; the disease is immune system disorder.
