Recent genomic research has identified interleukin-23 receptor (IL23R), nucleotide-binding oligomerization domain containing 2 caspase-activation recruitment domain?15 (NOD2/CARD15), autophagy related 16-like 1 (ATG16L1) and paired-like homeobox 2b (PHOX2B) as susceptibility loci for Crohn's Disease (CD). Our aim was to investigate these gene variants in a group of CD patients and to analyse the correlation to sub-phenotypes such as gender, smoking habits, disease behaviour at diagnosis, severity of disease and extra-intestinal manifestations. Nineteen patients with CD and 20 healthy controls were included in the study. The gene variants IL23R rs7517847 and rs11209026, NOD2/CARD15 rs2066845, PHOX2B rs16853571, ATG16L1 rs2241879 and rs2241880 were genotyped by PCR followed by sequencing. The frequency of the G risk allele of IL23R rs7517847 was found to be increased in patients with CD (42%) compared to that in control subjects (20%) [odds ratio (OR), 2.9; 95% confidence interval [CI], 1.06-7.9; P=0.03]. In addition, the homozygous condition GG was also associated with CD (OR, 8.70; 95% CI, 0.9-81.6; P=0.038). The analysis of correlation of genotype to sub-phenotypes showed an association of ATG16L1 rs2241879 with the lack of extra-intestinal manifestations (OR, 0.03; 95% CI, 0.002-0.45; P=0.006), and the patients defined as non-smokers displayed an increased frequency of the risk allele C (P=0.03). The present study confirms the association of the heterozygous and homozygous IL23R rs7517847 variant with CD and suggests an additive effect of smoking to the ATG16L1 rs2241879 C risk allele SNP, in the context of the multifactorial model established for the development of CD and a protective effect of the same allele against extra-intestinal manifestations. 相似文献

Autophagy is a highly conserved mechanism of eukaryotic cells implicated in cell homeostasis and elimination of intracellular pathogens. Functional polymorphisms in genes encoding for autophagy have been associated with susceptibility to inflammatory and infectious diseases, but data on severe infections are missing. The aim of the present study was to assess whether polymorphisms in genes encoding proteins involved in autophagy influence susceptibility to ventilator-associated pneumonia (VAP). Mechanically ventilated patients with VAP were studied. Genotyping for autophagy-related 16-like 1 (ATG16L1, rs2241880) functional polymorphism was performed using the TaqMan single-nucleotide assay. Monocytes were isolated from patients and stimulated with lipopolysaccharide (LPS). Tumor necrosis factor-α (TNF-α) was measured in the supernatants of monocytes using an enzyme-linked immunosorbent assay. Procalcitonin (PCT) was also measured in the serum of patients by an immuno-time-resolved amplified cryptate technology assay. A total of 155 patients with VAP were enrolled in the study. Carriage of the minor A allele of ATG16L1 was associated with septic shock with at least one organ failure (odds ratio (OR): 2.40, p: 0.036). TNF-α production was significantly greater among the carriers of the polymorphism presenting with at least one organ failure (p: 0.040). PCT was increased upon worsening to septic shock and organ failure only among carriers of the minor frequency A alleles. In a homogeneous cohort of septic patients with VAP, the carriage of autophagy polymorphisms predisposes to VAP severity and septic shock development. This may be related with predisposition to immunoparalysis. 相似文献

We analysed a polymorphism of the interleukin (IL)-1 receptor antagonist (IL1RN) gene in 93 Japanese patients with palmoplantar pustulosis (PPP). None of the IL1RN alleles was significantly increased in the patients compared with controls. Because PPP has been reported to be associated with the tumour necrosis factor (TNF) region, we examined the association between the TNF and IL1RN genes. There was a difference in IL1RN*2 positivity between patients with and without the AA genotype of the TNF gene. In contrast, such a difference was not found in controls. These data indicate a possible epistatic effect between TNF and IL1RN linked genes for susceptibility to the pathogenesis of PPP. 相似文献

We investigated the association of polymorphisms in the tumor necrosis factor (TNF) microsatellite as well as the promoter region of the TNFA gene and the TNFB gene with palmoplantar pustulosis (PPP). In order to clarify the heterogeneity of this disease, we performed a tonsillar provocation test on 78 patients and divided them into two groups according to the results; provocation positive (PP; n = 38) and provocation negative (PN; n = 40). We found that the phenotype frequency of the TNFB2 allele of the TNFB gene in the PN group was significantly higher than in controls (p = 0.0022, corrected p = 0.0044). There was also a significant increase in the frequency of allele B of the TNFA gene (TNFApB) in the PN group when compared with controls (p = 0.0049, corrected p = 0.025). Although there are no significant differences in the frequency of TNFa microsatellites, the frequency of the TNFd7 allele increased and that of the TNFd4 allele decreased in the PN group. An extended haplotype analysis revealed that the TNFd7-TNFApA-TNFB2 haplotype was more frequent in the PN group, implying that the PN group is associated with a low level of TNF-alpha production. These results indicate that detection of polymorphisms at the TNF locus may be a marker for determination of the heterogeneity of the disease, and that the allelic variation may influence the susceptibility. 相似文献

The etiology of growth impairment in Crohn's disease (CD) has been inadequately explained by nutritional, hormonal, and/or disease‐related factors, suggesting that genetics may be an additional contributor. The aim of this cross‐sectional study was to investigate genetic variants associated with linear growth in pediatric‐onset CD. We genotyped 951 subjects (317 CD patient–parent trios) for 64 polymorphisms within 14 CD‐susceptibility and 23 stature‐associated loci. Patient height‐for‐age Z‐score < ?1.64 was used to dichotomize probands into growth‐impaired and nongrowth‐impaired groups. The transmission disequilibrium test (TDT) was used to study association to growth impairment. There was a significant association between growth impairment in CD (height‐for‐age Z‐score < ?1.64) and a stature‐related polymorphism in the dymeclin gene DYM (rs8099594) (OR = 3.2, CI [1.57–6.51], p = 0.0007). In addition, there was nominal over‐transmission of two CD‐susceptibility alleles, 10q21.1 intergenic region (rs10761659) and ATG16L1 (rs10210302), in growth‐impaired CD children (OR = 2.36, CI [1.26–4.41] p = 0.0056 and OR = 2.45, CI [1.22–4.95] p = 0.0094, respectively). Our data indicate that genetic influences due to stature‐associated and possibly CD risk alleles may predispose CD patients to alterations in linear growth. This is the first report of a link between a stature‐associated locus and growth impairment in CD. 相似文献

Mycobacterium avium subspecies paratuberculosis (MAP) has been controversially linked with Crohn’s disease (CD). Detection of MAP in CD has been highly variable, and one explanation might be the genetic heterogeneity of this syndrome. Many of the single nucleotide polymorphisms (SNPs) linked with CD are contained within genes that are associated with bacterial handling in general, and some are specifically implicated in susceptibility to mycobacterial disease. We tested a cohort of IBD patients (n = 149) to determine whether the presence of MAP was associated with a selection of these SNPs. Blood samples from CD patients (n = 84), ulcerative colitis (UC, n = 65) patients and healthy controls (n = 55) were examined for the presence of MAP and SNPs in ATG16L1, IL12B, NOD2/CARD15, NKx2-3, IL23R and IRGM. Statistical analysis was then used to determine whether there was any association between the presence of MAP and these SNPs. MAP, rs2241880 (ATG16L1) and rs10045431 (IL12B) were found to be significantly associated with CD. The presence of MAP was not related to the status of the SNPs in ATG16L1 or IL12B. We have found no evidence for the contribution of these SNPs to the presence of MAP in CD patients. 相似文献

A candidate gene for TIMP-1 gene located on the X-chromosome (rs4898) was selected for a control case study to investigate a possible association of this SNP with the susceptibility to systemic sclerosis and its digit ulcer manifestation. A total of 461 individuals of Italian Caucasian origin (228 SSc patients and 233 healthy control subjects) were genotyped for TIMP-1 +372 T/C single nucleotide polymorphism rs4898. Subgroups were analyzed according to the presence or absence of digital ulcers. The CC genotype and C allele frequencies were significantly lower in female SSc patients than in controls (OR 0.53, CI 0.29-0.96, p=0.03 and OR 0.72, CI 0.53-0.98 p=0.04, respectively). CC genotypes frequency was lower also in female patients with ulcers than those without ulcers (OR 0.37, CI 0.14-1.00, p=0.03). Furthermore, CC genotype and C allele frequencies were lower also in female patients with ulcers in comparison to female healthy control subjects (OR 0.27, CI 0.10-0.70, p=0.004; OR 0.60, CI 0.40-0.89, p=0.01, respectively). The TIMP-1 rs4898 polymorphism may play a protective role in the susceptibility to SSC in females, and in particular to digital ulcer formation. 相似文献

We investigated the allele and genotype distribution of a polymorphism of the tumor necrosis factor (TNF) B gene and the frequency of HLA-DR9 in 49 patients with Palmoplantar pustulosis (PPP) and 51 healthy controls. We found that the frequency of TNFB2 in the PPP patients was significantly higher than that in the controls. Furthermore, the DR9-TNFB2 haplotype was significantly more frequent in the PPP patients (P=0.0045). These results suggest that TNFB2 may confer susceptibility to PPP. 相似文献

Data obtained from a mouse model indicated that the ectopic expression of the Grm1 gene is sufficient for transforming melanocytes and causing malignant melanoma in vivo. In addition, it has also been documented that the GRM1 gene is aberrantly expressed in human melanomas. Here we have performed a genetic association study to elucidate whether the GRM1 gene contributes to human melanoma susceptibility. To carry out this study, we initially genotyped 250 melanoma patients and 329 nonselected and nonrelated controls with three single nucleotide polymorphisms, rs854145, rs362962 and rs6923492, located in the intron 1, intron 4 and exon 10 of the GRM1 gene, respectively. To perform sample genotyping, we used pyrosequencing techniques. Regarding rs854145 and rs6923492, there were no differences in genotypic distribution or allelic frequency between patients and controls. However, we observed (i) a higher frequency of patients carrying the C allele of rs362962 than in controls (OR=1.40, CI=[1.01-1.95], P=0.045), and (ii) that difference became greater in a subgroup of patients with a low level of sun exposure and tumours located on the trunk and extremities (OR=2.10, CI=[1.26-3.51], P=0.0039). To confirm these observations, the sample size of both patient and control groups was increased. In total, 464 patients and 561 controls were genotyped for the rs362962 polymorphism. Only the second observation was confirmed (OR=1.69, CI=[1.16-2.47], P=0.0064). Our results suggest that the GRM1 gene may contribute to melanoma susceptibility in that specific group of patients. 相似文献

The host genetic compound plays a vital role in determining clinical outcomes of hepatitis B virus (HBV) infection. The tumor necrosis factor receptor-associated factor family member-associated nuclear factor-κB (NF-κB) activator (TANK) takes part in the tumor necrosis factor-α (TNF-α)-mediated NF-κB signaling pathway and the interferon (IFN)-induction pathways that have relevance to HBV-related liver disease. In this report, we explored whether the intronic polymorphism rs3820998 of the TANK gene was associated with outcomes of HBV infection by binary logistic regression analysis. A total of 1305 unrelated Han Chinese patients recruited from Wuhan, including 180 acute-on-chronic hepatitis B liver failure (ACLF-HBV) patients, 331 HBV-related liver cirrhosis (LC) patients, 308 HBV-related hepatocellular carcinoma (HCC) patients, and 486 asymptomatic HBV carriers (AsC) were genotyped using the TaqMan probe method. Logistic analysis revealed that the single-nucleotide polymorphism (SNP) rs3820998 was significantly associated with susceptibility to ACLF-HBV (dominant model, OR 0.643, 95% CI 0.428,0.964, p=0.033; additive model, OR 0.640, 95% CI 0.414,0.990, p=0.045), and LC (recessive model, OR 0.398, 95% CI 0.164,0.966, p=0.042; additive model, OR 0.379, 95% CI 0.155,0.928, p=0.034). These results indicate that the G > T variant is a protective factor in the development of ACLF-HBV and LC, and that the SNP rs3820998 in the TANK gene may play a role in mediating susceptibility to ACLF-HBV and LC in a Chinese Han population. 相似文献

Analysis of BTNL2 genetic polymorphisms in British and Dutch patients with sarcoidosis 总被引:2,自引:0,他引:2

Sarcoidosis is a heterogeneous disorder, both phenotypically and genetically. Two independent studies have recently shown that a functional polymorphism within butyrophilin-like 2 (BTNL2) gene predisposes to sarcoidosis independently of the human leukocyte antigen (HLA)-DRB1 alleles. However, in both studies, data analysis was not stratified by L?fgren's syndrome, a clinically and genetically distinct sarcoidosis subset. BTNL2, potentially encoding an immune coreceptor, is adjacent and in linkage disequilibrium (LD) with HLA-DRB1. We investigated six BTNL2 variants, including the functional rs2076530 (G > A), as well as HLA-DRB1 alleles, by sequence-specific primers-polymerase chain reaction, in 288 patients and 446 controls from two European countries. In the patient group as a whole, the HLA-DRB1*14 [odds ratio (OR) = 3.1, P(c) = 0.0003], DRB1*12 (OR = 2.5, P(c) = 0.003), and BTNL2 rs2076530 A allele (OR = 1.49, P(c) = 0.002) were all associated with disease susceptibility. However, after exclusion of patients presenting with L?fgren's syndrome and after adjusting for HLA-DRB1 alleles, the association between BTNL2 rs2076530 A and disease disappeared (P = 0.23). By contrast, both HLA-DRB1*14 and DRB1*12 remained strongly significant (OR = 3.60, P < 0.0001 and OR = 3.03, P = 0.003, respectively). BTNL2 haplotype 4, tagged by the rs2076530 G allele, also remained associated with non-L?fgren sarcoidosis after adjusting for HLA-DRB1 alleles (OR 0.37, P = 0.016). In summary, HLA-DRB1*14, DRB1*12, and BTNL2 haplotype 4--but not rs2076530 A--are associated with non-L?fgren sarcoidosis. However, the tight LD across the HLA complex makes it difficult to identify the precise location of the susceptibility locus/i. Larger sample sets from different ethnic groups, finer mapping, and more robust LD analyses across the HLA region are needed. 相似文献

Type 2 diabetes (T2D) is a chronic degenerative disease that involves the participation of several genetic and environmental factors. The objective of the study was to determine the association of the IRS1 (rs1801278), CAPN10 (rs3792267), TCF7L2 (rs7903146 and rs12255372), and PPARG (rs1801282) gene polymorphisms with T2D, in two different Mexican populations. We conducted a case-control replication study in the state of Guerrero and in Mexico City, with 400 subjects from Guerrero and 1065 from Mexico City. Data were analyzed by logistic regression, adjusting by ancestry, age, gender, and BMI, to determine the association with T2D. Heterozygosity for the Gly972Arg variant of the IRS1 gene showed the strongest association for T2D in both analyzed samples (OR = 2.43, 95% CI 1.12-5.26 and 2.64, 95% CI 1.37-5.10, respectively). In addition, an association of two SNPs of the TCF7L2 gene with T2D was observed in both cities: rs7903146, (for Guerrero OR = 1.98 CI95% 1.02-3.89 and for Mexico OR = 1.94 CI95% 1.31-2.88) and rs12255372 (OR = 1.79 CI95% 1.08-2.97, OR = 1.78 CI95% 1.17-2.71 respectively). We suggest that our results provide strong evidence that variation in the IRS1 and TCF7L2 genes confers susceptibility to T2D in our studied populations. 相似文献

We conducted a genome-wide association study on cutaneous basal cell carcinoma (BCC) among 2045 cases and 6013 controls of European ancestry, with follow-up replication in 1426 cases and 4845 controls. A non-synonymous SNP in the MC1R gene (rs1805007 encoding Arg151Cys substitution), a previously well-documented pigmentation gene, showed the strongest association with BCC risk in the discovery set (rs1805007[T]: OR (95% CI) for combined discovery set and replication set [1.55 (1.45-1.66); P= 4.3 × 10(-17)]. We identified that an SNP rs12210050 at 6p25 near the EXOC2 gene was associated with an increased risk of BCC [rs12210050[T]: combined OR (95% CI), 1.24 (1.17-1.31); P= 9.9 × 10(-10)]. In the locus on 13q32 near the UBAC2 gene encoding ubiquitin-associated domain-containing protein 2, we also identified a variant conferring susceptibility to BCC [rs7335046 [G]; combined OR (95% CI), 1.26 (1.18-1.34); P= 2.9 × 10(-8)]. We further evaluated the associations of these two novel SNPs (rs12210050 and rs7335046) with squamous cell carcinoma (SCC) risk as well as melanoma risk. We found that both variants, rs12210050[T] [OR (95% CI), 1.35 (1.16-1.57); P= 7.6 × 10(-5)] and rs7335046 [G] [OR (95% CI), 1.21 (1.02-1.44); P= 0.03], were associated with an increased risk of SCC. These two variants were not associated with melanoma risk. We conclude that 6p25 and 13q32 are novel loci conferring susceptibility to non-melanoma skin cancer. 相似文献
