IGF1 and familial pancreatic carcinoma: 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.
