For the contrast of Her2-enriched vs TNBC subtypes, the gene with the most interactions was CPD, closely followed by genes ERBB2 (oncogene, breast, and pan-cancer), GRB7 (oncogene; breast cancer), and LASP1 (DRG; liver, esophageal, leukemia, brain, thyroid gland, lung, and stomach cancer), all of which belong to the Her2 amplicon (chromosome region 17q-12-21) [98]. The gene discussed is GRB7; the disease is leukemia.
