The mRNA of PITPNM1 of TCGA breast cancer samples was significantly higher in triple-negative cancer (TNBC, 1.64-fold, p < 0.0001, n = 160) as well as HER2 over-expression in breast cancer (1.99-fold, p < 0.0001, n = 33) and luminal A/B (1.55-fold, p < 0.0001, n = 711), compared to normal breast tissue (n = 113, Figure 1A). This evidence concerns the gene ERBB2 and breast cancer.
