Polymorphism in NOD2, Crohn's disease, and susceptibility to pulmonary tuberculosis.

چکیده
The nucleotide oligomerization binding domain 2 gene (NOD2) encodes an intracellular receptor for bacterial components, which is expressed in monocytes and is associated with Crohn's Disease (CD). This finding, along with epidemiological evidence, supports a role for infection in the pathogenesis of CD. Speculation that mycobacteria are involved in CD led us to investigate NOD2 in susceptibility to tuberculosis (TB), a global public health problem caused by Mycobacterium tuberculosis. CD-associated NOD2 variants were absent in a case-control study of 640 Gambians, where CD is rare. Novel NOD2 promoter polymorphisms were identified but showed no association with TB in this African population sample.

Abstract Background: NOD2 gene located on chromosome 16 (IBD1) is known to have a strong association with Crohn’s disease. Three common polymorphisms of this gene including R702W, G908R, 1007fsinsC, were reported to be frequent in many western populations while rare occurrence of them was observed in eastern countries. The aim of this study was to assess the frequency of these polymorphisms ...
متن کاملCrohn's disease susceptibility genes are associated with leprosy in the Vietnamese population.
A genomewide association study in Chinese patients with leprosy detected association signals in 16 single-nucleotide polymorphisms (SNPs) belonging to 6 loci, of which 4 are related to the NOD2 signaling pathway and are Crohn's disease susceptibility loci. Here, we studied these 16 SNPs as potential leprosy susceptibility factors in 474 Vietnamese leprosy simplex families. We replicated SNPs at...
متن کاملCARD15/NOD2 polymorphisms are associated with severe pulmonary sarcoidosis.
Sarcoidosis and Crohn's disease are heterogeneous systemic diseases characterised by granulomatous inflammation. Caspase recruitment domain (CARD)15 is a major susceptibility gene for Crohn's disease, and specifically for ileal and fibrostenotic subtypes. The C-C chemokine receptor (CCR)5 gene has been associated with both parenchymal pulmonary sarcoidosis and perianal Crohn's disease. This stu...
متن کاملA novel single nucleotide polymorphism within the NOD2 gene is associated with pulmonary tuberculosis in the Chinese Han, Uygur and Kazak populations
BACKGROUND The present study aimed to investigate the genetic polymorphisms in exon 4 of the NOD2 gene in tuberculosis patients and healthy controls, in order to clarify whether polymorphisms in the NOD2 gene is associated with tuberculosis. METHODS A case-control study was performed on the Chinese Han, Uygur and Kazak populations. Exon 4 of the NOD2 gene was sequenced in 425 TB patients and ...
متن کاملNOD2 Polymorphisms and Pulmonary Tuberculosis Susceptibility: A Systematic Review and Meta-Analysis
The association between NOD2 and tuberculosis (TB) risk has been reported widely, but the results of previous studies remained controversial and ambiguous. To assess the association between NOD2 polymorphisms and TB risk, a meta-analysis was performed. A literature search was conducted by using the PubMed, Ovid, ISI Web of Knowledge, Elsevier ScienceDirect, and Chinese National Knowledge Infras...
