The fold change (tumor vs normal adjacent tissue) and statistical significance (two-tailed t-test) are as follows: basal-a (4.57-fold, p = 1.34x10-52), Her2 (2.81-fold, p = 8.49x10-27), luminal B (2.53-fold, p = 2.50x10-47), luminal A (1.65-fold, p = 1.39x10-56), and basal-b/claudin-low (1.47-fold, p = 2.06x10-3). The gene discussed is ERBB2; the disease is neoplasm.
