 Adenoid cystic carcinomas (ACCs) from various anatomical sites harbor a translocation t(6;9)(q22-23;p23-24), resulting in MYB-NFIB gene fusion.     ///    We confirm that MYB-NFIB gene fusion is observed in mammary ACCs and that a subset lacks this abnormality.    ///    We confirm that MYB-NFIB gene fusion is observed in mammary ACCs and that a subset lacks this abnormality.     ///    Our aim was to investigate the frequency of MYB-NFIB gene fusion in mammary ACCs with a focus paid to SBACC.     ///    "Additional validation with long-term follow-up is needed to determine the relationship, if any, between MYB-NFIB gene fusion and clinical outcome. "    ///    MYB-NFIB gene fusion in adenoid cystic carcinoma of the breast with special focus paid to the solid variant with basaloid features..     ///    "MYB rearrangement and MYB-NFIB fusion were assessed by fluorescence in situ hybridization and reverse-transcription polymerase chain reaction, respectively. "    ///    MYB-NFIB fusion status did not correlate with clinical outcome in studied patients.
