Compared also to normal tissue, CDK12 was found to be overexpressed in invasive ductal and lobular carcinoma, invasive breast carcinoma, and intraductal cribriform breast adenocarcinoma in the TCGA dataset, in invasive breast carcinoma in Gluck’s dataset, and in ductal breast carcinoma in situ in Ma’s dataset. This evidence concerns the gene CDK12 and intraductal cribriform breast adenocarcinoma.
