IHC staining of 70 collected breast cancer samples (Table 1) suggest significant differences in FA2H expression among patients of different subtypes (p = 0.003, Figure 2A, Table 3), and FA2H expression is significantly associated with the molecular features of luminal and TNBCs (p = 0.0012 and 0.0268 for luminal and TNBCs, respectively, Table 3). This evidence concerns the gene FA2H and breast carcinoma.
