Introduction: 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.
