Background A recent genome-wide association study has identified a new genetic variant rs7758229 in SLC22A3 for colorectal cancer susceptibility in a Japanese population, but it is unknown whether this newly identified variant is associated with colorectal cancer in other populations, including the Chinese population. Methods We examined the associations between rs7758229 and colorectal cancer risk among 1,147 cases and 1,203 controls matched by age and sex. Logistic regression model was used to assess the associations. Results No significant association was found between rs7758229 and colorectal cancer risk (OR = 0.95, 95%CI = 0.84–1.09, P = 0.463). Similar results were observed in the stratification of tumor location (OR = 0.94, 95%CI = 0.80–1.11, P = 0.481 for colon cancer, and OR = 0.96, 95%CI = 0.82–1.13, P = 0.621 for rectum cancer). Conclusions Our findings did not support an association between rs7758229 in 6q26-q27 and the risk of colorectal cancer in a Chinese population.
