Qualitative pathological variables, including pathological breast cancer type, progesterone receptor status, estrogen receptor status, and human epidermal growth factor receptor 2 status, showed no significant correlation with the different allele groups of CYP2C19, ALDH3A1, SLC22A16, and ABCB1 genes demonstrated no significant difference (p-value > 0.05) (Table 1). The gene discussed is CYP2C19; the disease is breast carcinoma.
