The hOGG1 Ser326Cys polymorphism is not associated with colorectal cancer risk (original) (raw)

Journal of epidemiology / Japan Epidemiological Association, 2007

Abstract

Little is known about the genetic risk factors associated with colorectal cancer. Although the Ser326Cys polymorphism of 8-oxoguanine DNA glycosylase (hOGG1) is consistently associated with a range of cancers, there is no consensus regarding this polymorphism and colorectal cancer risk. In the present study, conducted in a Korean population, we used the TaqMan assay to investigate whether the hOGG1 Ser326Cys polymorphism was associated with colorectal cancer in 439 colorectal cancer patients and 676 healthy normal controls. We also examined whether the hOGG1 Ser326Cys polymorphism is associated with tumor location, microsatellite instability (MSI) status and tumor-node-metastasis (TNM) stage in colorectal cancer. We found no significant difference between the cancer and control populations in terms of genotype distribution (CC, CG and GG). In addition, we found no association between the hOGG1 Ser326Cys polymorphism and cancer risk, MSI status, TNM stage or tumor location in colorec...
