ZHX2 and familial pancreatic carcinoma: miR-181a-2-3p is an oncogenic miRNA in pancreatic cancer and is located at the SNP site rs3802266 of the oncogene ZHX2 3′UTR creating a stronger binding site for miR-181a-2-3p, which has a stronger binding site with miR-181a-2-3p, thus increasing the risk of pancreatic cancer in the Chinese population [10].
