The expression of PITPNM1 in TNBC (1.48-fold, p < 0.0001, n = 299), HER2 over-expression in breast cancer tissues (1.59-fold, p < 0.0001, n = 127), and luminal A/B (1.25-fold, p < 0.0001, n = 1464) is higher than that in normal breast tissues (n = 147, Figure 1D). The gene discussed is ERBB2; the disease is breast cancer.
