Pyrin is mainly expressed in neutrophils and monocytes and is among the proteins involved in the interleukin-1 inflammatory pathway. | |||||||||||||||
| |||||||||||||||
|
Also, given that common variants in the NLRP3 region have previously been associated with CD [3] and that the gene products of NLRP3 and MEFV (i.e. | |||||||||||||||
| |||||||||||||||
|
Based on the identification of six common SNPs in the NLRP3 region contributing to CD susceptibility [3] and reports that the NLRP3 and MEFV gene products interact with each other and are involved in similar pathways, we sought to evaluate whether possible gene-gene interaction between the MEFV tagging SNPs and the NLRP3 six common SNPs could have masked an MEFV contribution to CD susceptibility. | |||||||||||||||
| |||||||||||||||
|
Several mutations have been identified of which the homozygous form of the M694V mutation is associated with a more severe expression of FMF. | |||||||||||||||
| |||||||||||||||
|
This clinical and epidemiological evidence linking IBD to the MEFV gene, together with the co-localization of the MEFV and NLRP3 gene products (pyrin and NALP3, respectively) within the same signaling pathway, suggested that MEFV could also contribute to CD and/or UC susceptibility. | |||||||||||||||
| |||||||||||||||
|
Mefv expression is significantly increased in trinitrobenzene sulfonic acid (TNBS)-induced (fold change ? | |||||||||||||||
| |||||||||||||||
|
The up-regulation of MEFV gene expression in the CD and UC patients, as well as in the mouse models, can be explained by the broad involvement of pyrin, the MEFV encoded protein, in the regulation of the inflammasome molecular platform and the inflammatory process [12][18]. | |||||||||||||||
| |||||||||||||||
|
Although these mutations are found throughout the gene, five sequence alterations in MEFV represent the majority of FMF chromosomes, four of which are clustered in exon 10 (i.e. | |||||||||||||||
| |||||||||||||||
|
Sequencing and subsequent genotyping of variants located in this associated haplotype block identified three synonymous variants (D102D/rs224225, G138G/rs224224, A165A/rs224223) and one non-synonymous variant (R202Q/rs224222) located in MEFV exon 2 that were significantly associated with UC (rs224222: p? | |||||||||||||||

No epistatic interactions are observed between NLRP3 and MEFV in the CD and UC combined Belgian-Canadian sample set | |||||||||||||||
| |||||||||||||||
|
Only coding SNPs within MEFV exon 2 (i.e. rs224225, rs224224, rs224223, and rs224222) were significantly associated with UC in the Belgian samples. | |||||||||||||||
| |||||||||||||||
|
block region of MEFV and UC in the exploratory phase, we excluded possible coding risk variants and non-MEFV genes located in this 5? | |||||||||||||||
| |||||||||||||||
|
To assess this latter possibility, since we knew that the MEFV and the NLRP3 gene product interacted with each other, we genotyped the six SNPs in the NLRP3 region that had been previously associated with CD [3] in both the Belgian and Canadian UC sample sets and performed gene-gene interaction analysis using these six NLRP3 SNPs and the 16 SNPs genotyped in the MEFV region (i.e. 12 tagging SNPs and 4 coding SNPs in MEFV exon 2 region). | |||||||||||||||
| |||||||||||||||
|
MEFV mutations in exon 10 do not contribute to CD and UC susceptibility | |||||||||||||||
| |||||||||||||||

|
However, significant associations were observed with three synonymous variants located in MEFV exon 2 (D102D/rs224225(C), G138G/rs224224(G), A165A/rs224223(A)) and UC in the Belgian combined sample set (p? | |||||||||||||||

In the third UC case-control cohort from Scotland (Edinburgh) (Table 1), only the A allele of tagging SNP rs224215 located in MEFV intron 2 was significantly associated with UC (p? | |||||||||||||||
