Abstract
Objective: XRCC4 play a key role in nonhomologous end-joining repair pathway. Alterations in DNA repair gene have been shown to reduce DNA repair capacity thereby inflicting carcinogenesis.
Methods: In a hospital-based case-control study, 192 prostate cancer (PCa) and 224 healthy controls. They were genotyped for XRCC4 G-1394T (rs6869366), intron 3 (rs28360071) intron 7 (rs28360317) and intron 7 (rs1805377), polymorphisms using polymerase chain reaction–restriction fragment length polymorphism.
Result: Carriers of GG genotype of rs6869366 were at reduced risk. Del/Del of rs28360071 and 28360317 demonstrated increased risk. The haplotype analysis was observed to be associated with a significant increase in PCa risk. Combined genotype of rs6869366, rs28360071 and rs1805377 have shown significant risk with high Gleason grade.
Conclusion: Our results suggested that the variant genotype of XRCC4 rs28360071 and rs28360317 and haplotype analysis may be associated with PCa risk.
