title: Association of lipoprotein receptor, receptor-associated protein, and metabolizing enzyme gene polymorphisms with gallstone disease: A case-control study.
abstract: BACKGROUND
  To identify high risk alleles for gallstone disease, we analyzed association of LDLRAvaII, LRPAP1 insertion/deletion, CETPTaqI B, and LPLHindIII polymorphisms with gallstone disease.
  
  
  METHODS
  In DNA samples of 214 gallstone patients and 322 age and sex matched controls, specific region containing polymorphisms was PCR amplified and digested with restriction enzymes except for LRPAP1 insertion/deletion polymorphism.
  
  
  RESULTS
  LRPAP1 gene insertion/deletion polymorphism was found to be significantly associated with gallstone disease. Genotype II was conferring significant risk for gallstone disease in females only (P=0.019; OR 2.577, 95% CI 1.144-5.806). LDLRAvaII, CETPTaqI B, and LPLHindIII polymorphisms were not found to be associated with gallstone disease either at genotype or allele level.
  
  
  CONCLUSIONS
  LRPAP1, II genotype carrier females may have increased risk for gallstone disease. On the other hand, LDLR AvaII, CETP TaqI B, and LPL HindIII polymorphisms may not be associated with gallstone disease.
