Bile Duct Cysts, also known as choledochal cyst, is related to biliary papillomatosis and cholangiocarcinoma. An important gene associated with Bile Duct Cysts is GPT (Glutamic--Pyruvic Transaminase), and among its related pathways/superpathways are Embryonic and Induced Pluripotent Stem Cells and Lineage-specific Markers and Synthesis of bile acids and bile salts. The drugs Hydrocortisone and Hydrocortisone acetate have been mentioned in the context of this disorder. Affiliated tissues include liver and pancreas, and related phenotypes are liver/biliary system and endocrine/exocrine gland
