EOC is divided into two types, some of the tumors that are called Type I derived from borderline tumors including low grade serous and mucinous tumors which have high frequency mutations in k-ras, CTNNB1, PTEN, PIK3CA, BRAF, ERBB2 (25), but some of the tumors that are called Type II, derived from intraepithelial pathological cells in the fallopian tube and are characterized by TP53 mutations. Here, CTNNB1 is linked to mucinous neoplasm.
