They identified commonly mutated genes that characterize pancreatic ductal adenocarcinomas (KRAS, TP53, SMAD4, and CDKN2A) and also identified two additional genes not previously described in human pancreatic ductal adenocarcinomas (KDM6A and PREX) [11-13]. This evidence concerns the gene KDM6A and pancreatic ductal adenocarcinoma.
