ACE and breast cancer: For the molecular subtype of BC (see Table 2), we found P4HA1, SLC12A2, KCNJ11 and CA12 were associated with luminal A-like BC with nominal significance, P4HA1, SLC12A2, ATP1A1, NR3C1, CA12, CACNA1D and GPR35 for luminal B-like BC, SLC12A2 and SCNN1D for luminal B/HER2-negative-like BC, ACE for HER2-enriched-like BC and AOC1 for triple-negative BC.
