BCOR: BCL-6 corepressor gene, EGFR: epidermal growth factor receptor, ERBB4: Erb-B2 receptor tyrosine kinase 4, FA: fibroadenoma, FEL: fibroepithelial lesion, FLNA: filamin A, MAP3KQ: mitogen-activated protein kinase 3, MED 12: mediator complex subunit 12, MLL2/KMT2D: mixed lineage leukemia 2, NF-1: neurofibromatosis type 1, PIK3CA: phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha, PT: phyllodes tumor, RARA: retinoic acid receptor, alpha, RB 1: retinoblastoma 1, SETD2: SET domain containing 2, TERT: telomerase reverse transcriptase. This evidence concerns the gene MAP4K3 and Fibroadenoma.
