Genetic association of polymorphisms in AXIN1 gene with clear cell renal cell carcinoma in a Chinese population

The purpose of the present study is to investigate the association between the polymorphisms in AXIN1 with susceptibility to clear cell renal cell carcinoma (ccRCC). A total of 284 ccRCC patients and 439 healthy volunteers were enrolled. Totally three tag single nucleotide polymorphisms in AXIN1 gene were genotyped using PCR & restriction fragment length polymorphism. Significantly increased ccRCC risk was observed to be associated with the CT/CC genotypes of rs1805105 and AA genotype of rs12921862. Patients carrying the rs1805105 CT genotype had a 1.92-fold increased risk to developing clinical stage III and IV cancer. Our results suggested the rs1805105 CT/CC genotypes and rs12921862 AA genotype may relate to ccRCC development.
