title: [Association of polymorphisms of apolipoprotein B gene with cholesterol gallstone disease].
abstract: OBJECTIVE
  To investigate the association between the apolipoprotein B (apoB) gene polymorphic sites Ins/Del and Xbal, and cholesterol gallstone disease.
  
  
  METHODS
  The two polymorphic sites of apoB gene were examed in 101 cholesterol gallstone patients and 50 controls by polymerase chain reaction and restriction fragment length polymorphism methods.
  
  
  RESULTS
  For Xbal polymorphic site, the frequency of the rare allele X+ and the distribution of X+X- genotype were significantly higher in the patient group than in the control group (P < 0.05). For Ins/Del polymorphic site, no significant difference was found in allele frequency and genotype distribution between the patient group and the control group.
  
  
  CONCLUSIONS
  Xba1 polymorphism of apoB gene may be associated with cholesterol gallstone disease. The association, however, is not present for Ins/De1 polymorphism of apoB gene with cholesterol gallstone disease.
