In pancreatic cancer, differential hydroxymethylation of genes related to pancreas development or function (GATA4, GATA6, PROX1, ONECUT1, MEIS2), and cancer pathogenesis (YAP1, TEAD1, PROX1, IGF1) have also been shown to reliably identify pancreatic cancer from peripheral blood samples. This evidence concerns the gene GATA4 and pancreatic neoplasm.
