We examined the status of GNAS mutation at codon 201 and KRAS mutation at codon 12&13, degree of mucin production and immunohistochemical expressions of MUC mucin core proteins in 29 individuals (M/F=15/14) with IPNB in intrahepatic and perihilar bile ducts (perihilar IPNB) and 6 individuals (M/F=5/1) with IPNB in distal bile ducts (distal IPNB)
