[PMID 18371140] Carriers of any of several NOD2 variant SNPs do not respond well to treatment of perianal fistulating Crohn's disease by the antibiotics ciprofloxacin or metronidazole, whereas carriers of wild-type NOD2 genes have at least some chance (1 in 3) of responding well.
[PMID 17724347] NOD2/CARD15 SNP variants are associated with an increased risk of relapse and death for patients with acute leukemia after hematopoietic stem-cell transplantation (HSCT) with unrelated donors as compared with wild-type pairs. NOD2/CARD15 genotyping before transplantation may contribute to prognosis and influence clinical management.
[PMID 18756601] No association was found for NOD2/CARD15 SNPs (R702W, G908R) in Chinese patients with inflammatory bowel disease.
[PMID 11385576] These observations suggest that the NOD2 gene product confers susceptibility to Crohn's disease by altering the recognition of these components and/or by over-activating NF-kB in monocytes, thus documenting a molecular model for the pathogenic mechanism of Crohn's disease that can now be further investigated.
