TCGA patient gene expression (left) and GO term enrichment (biological processes) (right) for genes from regions exhibiting (d) BA_AA lung-permissive changes in the luminal metastatic breast cancer subtype, (e) AB_BB lung-permissive changes in case of HER2-enriched metastatic breast cancer subtype, or (f) BA_AA lung-permissive changes in case of triple-negative metastatic breast cancer subtype. Here, ERBB2 is linked to breast carcinoma.
