The 3 genes (FOSL1, ACSBG1, and C21orf37) were downregulated in our patients with ER-negative BCs (log2-fold change: −0.37; −0.16; −0.34; adjusted P < 0.05), and PR-negative BCs (log2-fold change: −0.28; −0.15; −0.18; adjusted P < 0.05); and upregulated in patients having a family history of ovarian cancer (log2-fold change: 1.08; 0.5; 0.8; adjusted P < 0.05). Here, FOSL1 is linked to ovarian carcinoma.
