Furthermore, the boy's genomic profile revealed not only positivity for the typical SBC's translocation t(12;15), but also for a 3q28 duplication, found in his father (healthy) and paternal grandfather (with a previous BC).None were positive for BRCA mutation.
Despite the limited interest, in recent years it has become apparent that the histopathological characteristics of these cancers may be underpinned by distinct arrays of genetic changes, providing direct evidence for genotypic-phenotypic correlations between morphological patterns and molecular changes in breast cancer (eg t(12;15) in secretory carcinoma of the breast).
