Using Oncomine, we determined that FOXA1 is overexpressed in mixed lobular and ductal breast carcinoma, intraductal cribriform breast adenocarcinoma, invasive ductal and lobular carcinoma, male breast carcinoma, invasive lobular breast carcinoma, mucinous breast carcinoma, tubular breast carcinoma, invasive ductal, and invasive lobular breast carcinoma. This evidence concerns the gene FOXA1 and breast ductal adenocarcinoma.
