Triple-negative breast cancers (TNBCs), which are characterized by a lack of estrogen receptor (ER), progesterone receptor, and human epidermal growth factor receptor 2 expression (HER2), account for 10–20% of breast cancer cases and are considered a poor prognostic factor due to their association with higher metastasis risk [11,12]. The gene discussed is ERBB2; the disease is triple-negative breast carcinoma.
