Indeed, this genotype is strongly associated with MDGA1 expression in GTEx transformed fibroblasts and lymphoblastoid cell lines (LCLs; P = 6.3 × 10− 13 and 1.4 × 10− 10 respectively; Fig. 3d and e) with the same directionality as the conventional model, suggesting that this is a strong candidate for a tumor eQTL driven by tumor-associated normal cell types, not cancer cells. The gene discussed is MDGA1; the disease is cancer.
