Among these are five mRNA candidates: CCND1 (encoding for cyclin D1), EGFR (encoding for epidermal growth factor receptor), FGF19 (encoding for fibroblast growth factor 19), FRS2 (encoding for fibroblast growth factor receptor substrate 2), and GREB1 (growth regulation by estrogen in breast cancer 1). This evidence concerns the gene FGF19 and breast carcinoma.
