Interestingly, despite the association with higher grade (p = 0.014) and Her-2 OE carcinomas (p = 0.020), 51.5% of the cases displaying the phenotype PPP2R2A-/low/Cyclin D1high would be otherwise classifiable as luminal A-like (Table 1) and the presence of the phenotype was also associated with both worse OS (HR 2.71, 95% CI 1.17–6.28, p = 0.020) and DFS (HR 2.63, 95% CI 1.26–5.11, p = 0.010) (Table 1 & Figure 6). Here, PPP2R2A is linked to carcinoma.
