Specifically, we gathered information about cellular compartment, disease status, receptor status (estrogen receptor, progesteron receptor, and HER2 amplification), PAM50 subtype, tumor histology, size, grade, TNM stage as well as the overall pathological stage, node positivity, recurrence, response to treatment, and patient’s age at diagnosis, ethnicity, and menopause status (Table 1 and Table 2 and Table S2). The gene discussed is ERBB2; the disease is neoplasm.
