Likewise, pancreatic carcinomas and their mucinous neoplastic precursors appear not to be driven by oncogenic BRAF, but instead are the only group apart from MOTs to harbor mutant CDKN2A. We also identified genes novel to cancer that may reflect rarely targeted genes unique to the mucinous ovarian milieu. This evidence concerns the gene CDKN2A and exocrine pancreatic carcinoma.
