ESR1 and breast cancer: The significant Pearson correlation between the log fold change (FC) in the SCAN-B and the TCGA cohorts (r = 0.93, p-value < 2.2e-16: ER status and r = 0.75, p-value < 2.2e-16: HER2 status) show that we identify with high confidence lncRNA differentially expressed according to pathological breast cancer subtypes.
