NOD2/CARD15 gene polymorphisms and sarcoidosis susceptibility: review and meta-analysis.

ABSTRACT: Background: The association between NOD2/CARD15 (nucleotide binding oligomerisation domain containing 2) gene polymorphisms and susceptibility to sarcoidosis have been extensively investigated in recent years. However, the results from previous studies remain controversial. To assess the association of NOD2/CARD15 polymorphisms and sarcoidosis susceptibility, we performed a meta-analysis. Methods: PubMed, Embase, CNKI and Wanfang databases were examined for all relevant studies up until 8th October 2016. In all, 968 cases and 1549 controls in eight case-control studies were included which mainly consisted of Caucasian participants. The relevant data were extracted and the odds ratio (OR) with 95% confidence intervals (95% CI) calculated to assess the strength of any associations. Statistical analyses were calculated using STATA12.0 software and Revman5.3 software. The associations between NOD2/CARD15 SNP rs2066844, rs2066845, rs2066847, rs1861759 polymorphisms and the risk of sarcoidosis were evaluated in allelic, dominant, recessive and additive models. Results: The pooled data showed that the NOD2/CARD15 rs2066845 polymorphism was associated with sarcoidosis susceptibility in allelic model (C vs. G, OR=1.86, 95% CI: 1.14-3.04, P=0.01), dominant model (GC + CC vs. GG, OR=1.84, 95% CI: 1.11-3.05, P=0.02) and additive model (GC vs. GG, OR=1.79, 95% CI: 1.08-2.97, P=0.02). However, the results suggested that the rs2066844, rs2066847 and rs1861759 polymorphisms might not be associated with a risk of sarcoidosis. Conclusions: This meta-analysis indicated that the 'C' allele of SNP rs2066845 may be a risk factor for sarcoidosis, especially in Caucasians, whilst rs2066844, rs2066847 and rs1861759 may not be associated with a risk of developing sarcoidosis.

Project description:AimTo assess whether the polymorphisms of NOD2/CARD15, autophagy-related 16-like 1 (ATG16L1), and interleukin-23 receptor (IL23R) genes play a more critical role in the susceptibility of childhood-onset than in adult-onset Crohn's disease (CD).MethodsPolymorphisms R702W, G908R, and 3020insC of NOD2/CARD15; rs2241880 A/G of ATG16L1, and rs11209026 (R381Q) of IL23R gene were assessed in 110 childhood-onset CD, 364 adult-onset CD, and 539 healthy individuals. Analysis of polymorphisms R702W, G908R, and 3020insC of NOD2/CARD15 genotyping was performed by allele specific polymerase chain reaction (PCR) or by PCR-restriction fragment length polymorphism analysis. The polymorphisms rs2241880 A/G of the ATG16L1, and rs11209026 (R381Q) of the IL23R gene in the children's cohort were genotyped by PCR and melting curve analysis whereas adult group genotyping was performed using the Affymetrix Genome-Wide Human SNP Array 5.0 (500K).ResultsThe 3020insC allele in NOD2/CARD15 was significantly higher in childhood than in adult-onset CD (P = 0.0067). Association with at least 1 NOD2/CARD15 variant was specific for ileal disease (with or without colonic involvement). Even if the frequency of G allele of the rs2241880 ATG16L1 polymorphism was increased in both paediatric and adult CD patients compared to controls (P = 0.017 and P = 0.001, respectively), no difference was observed between the childhood and the adult cohort. The rare Q allele of IL23R rs11209026 polymorphism was underrepresented in both paediatric and adult CD cases (P = 0.0018 and P = 0.04, respectively) and no difference was observed between the childhood and the adult cohort. The presence of the rs2241880 ATG16L1 and rs11209026 IL23R polymorphisms did not influence disease phenotype.ConclusionPolymorphism 3020insC in NOD2/CARD15 occurs statistically significantly more often in patients with childhood-onset CD than in patients with adult-onset CD. The ATG16L1 and IL23R variants are associated with susceptibility to CD, but not early-onset disease.
