Abstract: A method for diagnosing a risk of pancreatic cancer according to an embodiment of the present disclosure includes detecting mutation or functional decrease of one or more gene selected from a group consisting of ARSA (arylsulfatase A), CTSA (cathepsin A), GAA (acid alpha-glucosidase), GALC (galactosylceramidase), HEXB (hexosaminidase subunit beta), IDUA (iduronidase), MAN2B1 (mannosidase alpha class 2B member 1), NPC1 (NPC intracellular cholesterol transporter 1) and PSAP (prosaposin) from a biological sample of a subject, and determining that there is a higher risk of the pancreatic cancer when the mutation or functional decrease of the one or more gene is detected than when neither mutation decrease nor functional decrease is detected.
