In a recent study, exome sequencing of 22 PTs and targeted sequencing of 100 fibroepithelial neoplasms revealed the genetic profile of fibroepithelial neoplasms, with MED12 (73%) and RARA (32%) mutations common in fibroadenoma patients and in all pathologically classified PTs' patients [20]. Here, MED12 is linked to fibroepithelial neoplasm.
