For instance, compared with normal tissues of TCGA‐BRCA (Breast invasive carcinoma), we observed a lower expression level of GAS2 and GAS2L2 genes (Figure S2, p < 0.001), but a high expression level of GAS2L3 (p < 0.001) in the tumor tissues. The gene discussed is GAS2L3; the disease is invasive breast carcinoma.
