The cis-eQTL associations of 7 genes (TAPBPL, H1F0, SERPINB9, HMBOX1, MGST3, TMBIM4, THNSL2) are shared between GBM and cell lines/normal tissues; the association of 4 genes (TAPBPL, H1F0, HMBOX1, THNSL2) are common between GBM and Breast Cancer. This evidence concerns the gene MGST3 and breast carcinoma.
