Background: There is growing evidence that gallstone formation may be genetically determined. It was recently presented that a common polymorphism in the LRPAP1 gene might be associated with gallstone disease.
Aim: Since reproducibility of data is important in genetic association studies, a case control study was designed to find out whether LRPAP1 gene polymorphism is associated with gallstone disease in a Polish population.
Subjects: Two hundred eighty-nine Polish Caucasian gallstone disease patients and 251 healthy controls participated in the study.
Methods: A 37-bp insertion/deletion polymorphism in intron 5 of LRPAP1 (rs11267919) was determined by means of polymerase chain reaction assay.
Results: The frequencies and distribution of the insertion/deletion alleles did not differ significantly between gallstone disease patients and controls. No significant gender-related differences in allele frequencies or distributions were noted.
Conclusion: The LRPAP1 insertion/deletion polymorphism is not associated with gallstone disease in a Polish population.
