In Curtis's dataset [12], overexpression of STAT1 was found in all types of BC compared with normal samples, medullary BC with fold change = 6.511, invasive ductal BC with fold change = 3.025, invasive lobular BC with fold change = 2.223 and ductal breast carcinoma in Situ with fold change = 2.673 (Table 1). The gene discussed is STAT1; the disease is breast ductal adenocarcinoma.
