EYA2 mRNA level was significantly higher in high-grade cancer tissues [OR: 1.48 (1.22–1.80), I2 = 38.0%; Figure 1B) and HER2+ tumors [OR: 1.76 (1.28–2.42), I2 = 11.0%; Figure 1C] in comparison with low-grade tumor tissues and HER2– tumor tissues, respectively. The gene discussed is ERBB2; the disease is cancer.
