EGFR and breast cancer: Furthermore, expression of the classical breast cancer oncogenes EGFR (epidermal growth factor receptor) and v‐Myc avian myelocytomatosis viral oncogene neuroblastoma‐derived homolog (MYCN) was also positively correlated with CHD7 expression, with Spearman's r = 0.24 and 0.12, respectively (Fig. 3C and Table S9).
