Furthermore, a survival analysis on the METABRIC (Molecular Taxonomy of Breast Cancer International Consortium) dataset showed that a worse survival probability was associated with the lower BECN1 but not with the BRCA1 mRNA expression in all breast cancer types [30], indicating that in sporadic breast cancers, BECN1 is a driver rather than a passenger event. This evidence concerns the gene BECN1 and breast carcinoma.
