Arruabarrena-Aristorena et al. determine that mutations in the pioneer transcription factor FOXA1 lower the therapeutic response to aromatase inhibitors in ER+ breast cancer. Mechanistically, two phenotypic groups are established: hypermorphic Wing2 mutants that augment estrogen response, and a neomorphic SY242CS mutant that promotes an...

Metaplastic breast cancers (MBCs) are characterized by complex genomes, which seem to vary according to their histologic subtype. TERT promoter hotspot mutations and gene amplification are rare in common forms of breast cancer, but present in a subset of phyllodes tumors. Here, we sought to determine the frequency of genetic alterations...
