Abstract
AIM: To investigate the relationship between R702W, G908R and L1007fs polymorphisms of the NOD2/CARD15 gene and susceptibility to inflammatory bowel disease (IBD) in a Zhuang population in Guangxi, China.
METHODS: Intestinal tissue samples of 70 Zhuang and 76 Han unrelated IBD patients and 80 Zhuang and 84 Han unrelated healthy people were collected in Guangxi from February 2007 to October 2010. Genomic DNA was prepared from these intestinal samples and used to genotype the R702W, G908R and L1007fs polymorphisms of the NOD2/CARD15 gene by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
RESULTS: None of the patients with IBD and healthy controls had heterozygous or homozygous SNP variants. The distributions of genotype and allele frequencies were not significantly different between the IBD group and healthy control group. No significant differences were noted in the NOD2/CARD15 gene R702W, G908R and L1007fs polymorphisms among patients with Crohn's disease, ulcerative colitis and control subjects in Zhuang and Han populations in Guangxi (all P > 0.05). Gene mutation genotypes of the NOD2/CARD15 gene R702W, G908R and L1007fs polymorphisms were not found in these populations.
CONCLUSION: R702W, G908R and L1007fs polymorphisms of the NOD2/CARD15 gene are not associated with susceptibility to IBD in the Zhuang population in Guangxi.
