We found that IL1R1 (Il1r1 interleukin 1 receptor, type I), BCAR3 (breast cancer anti-estrogen resistance 3), KCNH2 (potassium channel, voltage gated related subfamily H, member 2), PIR (pirin), and ZDHHC23 (zinc finger, DHHC-type containing 23) were differentially expressed. The gene discussed is PIR; the disease is breast cancer.
