The objective of this study was to examine associations of single nucleotide polymorphisms, rs1045642 within the MDR1 gene and rs1799930 within the NAT2 gene, with the risk of colorectal cancer (CRC) in the population of Central Russia. DNA specimens were obtained from 178 patients with CRC (87 males and 91 females) and 327 age-matched healthy controls (179 males and 148 females). Genotyping was performed using real-time PCR. Association of the studied SNPs with the risk of CRC was evaluated using logistic regression analysis. It was demonstrated that MDR1 rs1045642 polymorphism was associated with the increased risk of CRC after correction for gender, age, and smoking (OR = 1.41, 95% CI = 1.09–1.83; P = 0.008). A gender-stratified analysis showed that MDR1 rs1045642 was associated with the increased risk of CRC only in females (OR = 1.62, 95% CI = 1.11–2.35; P = 0.01). In males, no association between MDR1 rs1045642 and CRC was found. Association between MDR1 rs1045642 and the increased risk of colorectal cancer in Russian females from Central Russia was revealed.
