By utilizing immunohistochemistry and PCR to examine FGFR2 expression and the presence of FGFR2 mutations in endometrial carcinoma, Gatius et al. determined that FGFR2 acted as an oncogene in EC and that FGFR2 expression was positively correlated with tumor stage and grade [22]. The gene discussed is FGFR2; the disease is endometrial carcinoma.
