Correlations between DSC2 mRNA levels and clinicopathological factors such as histological grading, stage, lymph node involvement, oestrogen and progesterone receptor status (ER, PR) and molecular subtype, showed a significant association between high DSC2 levels (Q4) and higher tumour grading (in one probe set), ER- (in one probe set and the mean value), PR-negativity (in one probe set) and molecular subtype (in two probe sets and the mean value), whereas no correlation between DSC2 and tumour stage or nodal status was found. Here, PGR is linked to neoplasm.
