Popis: Background The X-ray repair complementing defective repair in Chinese hamster cells 2 (XRCC2) is an important protein in response to DNA double-strand breaks (DSBs) in human cells. XRCC2, as a functional protein in the homologous recombination repair (HRR) process, has been identified to have several polymorphisms which might be associated with the risk of cancer. Therefore, we aimed to investigate a novel missense variation (AGC>AGG, p.Ser150Arg) in the XRCC2 gene for colorectal cancer susceptibility. Methods We studied 291 colorectal cancer (CRC) patients and 140 healthy individuals. ARMS PCR method was used to detect the AGC>AGG (p.Ser150Arg) variation in the XRCC2 gene. Results The results showed that there was a significant differential among CRC and controls in the genotypic and allelic frequencies (p AGG, p.Ser150Arg. Our results demonstrated that the G allele of XRCC2; AGC>AGG, p.Ser150Arg was associated with increased CRC risk (odds ratio = 59.04, 95% confidence interval = 18.6 - 186). This variation also influenced CRC cancer susceptibility in smokers (p Conclusions The G allele of XRCC2; AGC>AGG, p.Ser150Arg, may be a potential marker for CRC in Iranians and investigations in other populations are warranted for further universal application in CRC detection and prediction.
