Regarding cancer measurements, we observed a high correlation of HER2/CEP17 ratio, an average of HER2 copy number per cell, and an average of CEP17 copy number per cell between visual and IA quantification (PCC = 0.842, p < 0.001; PCC = 0.916, p < 0.001; PCC = 0.765, p < 0.001; respectively) (Fig. 1A, B, and C, respectively). The gene discussed is ERBB2; the disease is cancer.
