Abstract
PURPOSE Although a number of genetic studies have attempted to link organic cation transporter 1/2 (OCTN1/2) polymorphisms to susceptibility of Crohn's disease (CD), the results were often inconsistent. The present study aimed at investigating the associations. METHODS The PubMed, EBSCO, and BIOSIS databases were searched to identify eligible studies which were published in English before April 2011. The association was assessed by odds ratio (OR) with 95% confidence intervals (CI). RESULTS A total of 15 case-control studies, containing 4,489 cases/5,351 controls for OCTN1 and 4,474 cases/5,377 controls for OCTN2 were included. Overall, significant associations were found between OCTN1/2 polymorphisms and susceptibility of Crohn's disease for all genetic models. In the subgroup analyses, significant associations were found in the Caucasian population for OCTN1 (TT vs. CC: OR = 1.425, 95% CI 1.247-1.628; TT vs. CT: OR = 1.299, 95% CI 1.149-1.468; dominant model: OR = 1.344, 95% CI 1.197-1.508; and recessive model: OR = 1.179, 95% CI 1.066-1.305) and for OCTN2 (CC vs. GG: OR = 1.309, 95% CI 1.078-1.588; CC vs. CG: OR = 1.200, 95% CI 1.002-1.438; dominant model (OR = 1.231, 95% CI 1.036-1.462; recessive model: OR = 1.148, 95% CI 1.031-1.279). Significant associations were not found in the East Asian population. CONCLUSIONS This meta-analysis suggests that OCTN1/2 polymorphisms were associated with susceptibility of CD in the Caucasian population but not in the East Asian population.

The NOD2 single nucleotide polymorphisms rs2066843 and rs2076756 are novel and common Crohn's disease susceptibility gene variants. PLoS One 2010; 5:e14466. [PMID: 21209938 PMCID: PMC3012690 DOI: 10.1371/journal.pone.0014466] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2010] [Accepted: 11/18/2010] [Indexed: 12/19/2022] Open
Abstract
Background The aims were to analyze two novel NOD2 variants (rs2066843 and rs2076756) in a large cohort of patients with inflammatory bowel disease and to elucidate phenotypic consequences. Methodology/Principal Findings Genomic DNA from 2700 Caucasians including 812 patients with Crohn's disease (CD), 442 patients with ulcerative colitis (UC), and 1446 healthy controls was analyzed for the NOD2 SNPs rs2066843 and rs2076756 and the three main CD-associated NOD2 variants p.Arg702Trp (rs2066844), p.Gly908Arg (rs2066847), and p.Leu1007fsX1008 (rs2066847). Haplotype and genotype-phenotype analyses were performed. The SNPs rs2066843 (p = 3.01×10−5, OR 1.48, [95% CI 1.23-1.78]) and rs2076756 (p = 4.01×10−6; OR 1.54, [95% CI 1.28-1.86]) were significantly associated with CD but not with UC susceptibility. Haplotype analysis revealed a number of significant associations with CD susceptibility with omnibus p values <10−10. The SNPs rs2066843 and rs2076756 were in linkage disequilibrium with each other and with the three main CD-associated NOD2 mutations (D'>0.9). However, in CD, SNPs rs2066843 and rs2076756 were more frequently observed than the other three common NOD2 mutations (minor allele frequencies for rs2066843 and rs2076756: 0.390 and 0.380, respectively). In CD patients homozygous for these novel NOD2 variants, genotype-phenotype analysis revealed higher rates of a penetrating phenotype (rs2076756: p = 0.015) and fistulas (rs2076756: p = 0.015) and significant associations with CD-related surgery (rs2076756: p = 0.003; rs2066843: p = 0.015). However, in multivariate analysis only disease localization (p<2×10−16) and behaviour (p = 0.02) were significantly associated with the need for surgery. Conclusion/Significance The NOD2 variants rs2066843 and rs2076756 are novel and common CD susceptibility gene variants.
