Are the haplotypes of TNFRSF17 polymorphisms associated with colon cancer in a Korean population? Context: We previously found that the haplotypes of TNFRSF17 single nucleotide polymorphisms (SNPs) were associated with the susceptibility to inflammatory bowel disease on Korean population. The present study aimed to investigate whether the polymorphisms in the TNFRSF17 gene are associated with susceptibility to colorectal cancer (CRC). Genotype analysis in the TNFRSF17 SNPs was performed by high-resolution melting and TaqMan probe analysis, and the genotype and allele frequencies of TNFRSF17 SNPs were compared between the CRC patients and the healthy controls. The haplotype frequencies of TNFRSF17 for multiple loci were estimated using the expectation maximization algorithm. Although, the genotype and allelic frequencies of these SNPs, in the colon cancer and rectal cancer patients, were not significantly different from those in the healthy controls, the genotype and allele frequency of g.2493G>A was significantly different between the healthy controls and the right colon cancer patients (P = 0.014 and 0.004, respectively). Moreover, the haplotypes frequencies in the healthy controls were significantly different from those in the colon cancer patients.

Our results suggest that TNFRSF17 may be a candidate gene associated with the pathogenesis of colon cancer, and the haplotypes of the TNFRSF17 polymorphisms might be one of the markers for colon cancer susceptibility. Final Decision: yes
