Abstract
The article is devoted to the role of polymorphism of interleukins 2 and 6 in obstructive jaundice. The syndrome of obstructive jaundice, which develops as a result of diseases of the biliary tract, has genetically determined prerequisites. Our study suggests that carriers of the IL-6 C-174G gene allele have a high predisposition to biliary tract diseases, and carriers of the G T 330G allele of IL 2 gene polymorphism are a protective factor in the development of subhepatic cholestasis.
