Abstract
The predilection for women in systemic autoimmune diseases is well established. However, this sex bias in oral autoimmune diseases has been classically reported from an epidemiological perspective without any elaborate attempts to unveil the underlying mechanisms. The unique nature of the oral environment is likely to impose a combination of systemic and local factors that ultimately result in the sex bias in autoimmune diseases of the oral cavity. Variations of immune responses, target organ vulnerability, endocrine and genetic factors, sex chromosomes and modes of parental inheritance are potential systemic factors, while the oral microbiome, oral tolerance, saliva, and oral epithelial stem cells may account for local contributing factors. This review will discuss the preponderance of women in oral immune-mediated diseases, the potential systemic and local mechanisms underlying this predominance and highlight the crucial need for further research in this area.

Complex Inheritance of Rare Missense Variants in PAK2, TAP2, and PLCL1 Genes in a Consanguineous Arab Family With Multiple Autoimmune Diseases Including Celiac Disease. Front Pediatr 2022; 10:895298. [PMID: 35783297 PMCID: PMC9242504 DOI: 10.3389/fped.2022.895298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Accepted: 04/27/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Autoimmune diseases (AIDs) share a common molecular etiology and often present overlapping clinical presentations. Thus, this study aims to explore the complex molecular basis of AID by whole exome sequencing and computational biology analysis. METHODS Molecular screening of the consanguineous AID family and the computational biology characterization of the potential variants were performed. The potential variants were searched against the exome data of 100 healthy individuals and 30 celiac disease patients. RESULT A complex inheritance pattern of PAK2 (V43A), TAP2 (F468Y), and PLCL1 (V473I) genetic variants was observed in the three probands of the AID family. The PAK2 variant (V43A) is a novel one, but TAP2 (F468Y) and PLCL1 (V473I) variants are extremely rare in local Arab (SGHP and GME) and global (gnomAD) databases. All these variants were localized in functional domains, except for the PAK2 variant (V43A) and were predicted to alter the structural (secondary structure elements, folding, active site confirmation, stability, and solvent accessibility) and functional (gene expression) features. Therefore, it is reasonable to postulate that the dysregulation of PAK2, TAP2, and PLCL1 genes is likely to elicit autoimmune reactions by altering antigen processing and presentation, T cell receptor signaling, and immunodeficiency pathways. CONCLUSION Our findings highlight the importance of exploring the alternate inheritance patterns in families presenting complex autoimmune diseases, where classical genetic models often fail to explain their molecular basis. These findings may have potential implications for developing personalized therapies for complex disease patients.

Abstract
BACKGROUND Comorbidity is an important predictor of how disease course in inflammatory bowel (IBD) evolves. AIMS To determine pre-diagnosis relative rates (RR) and post-diagnosis hazard ratios (HR) of component diseases of the Charlson Comorbidity Index (CCI) in a cohort study of persons with IBD. METHODS The University of Manitoba IBD Epidemiology Database includes all Manitobans with IBD from 1 April 1984 through 31 March 2018 and matched controls. All outpatient physician claims and hospital discharge abstracts were searched for diagnostic codes for CCI component diseases. Some diseases were collapsed into one group such that we assessed 12 conditions. We report the RR of these conditions prior to IBD and the incidence of these diagnoses after IBD. Using Cox proportional hazards regression we report post-diagnosis HR. Confidence intervals were adjusted for Bonferroni correction. RESULTS The RR of cardiovascular diseases, peripheral vascular diseases, chronic pulmonary diseases, connective tissue disease/rheumatic diseases, renal disease, liver diseases, peptic ulcer disease, and cancer were all increased prior to diagnoses of IBD compared to controls. All comorbidities were increased post IBD diagnosis. The increased HR for dementia in persons with Crohn's disease was a concerning novel finding. The increased association with paraplegia/hemiplegia was unexpected. For all comorbidities, except diabetes, the age at diagnosis was younger in IBD than controls. CONCLUSIONS Persons with IBD have a higher comorbidity burden than persons without IBD. Optimal care plans for persons with IBD should include an assessment for other comorbidities that include just about every other organ system.

Abstract
Inflammatory bowel diseases (IBD) is an umbrella term that covers both ulcerative colitis (UC) and Crohn's disease (CD), which are chronic inflammatory conditions of the gastrointestinal system. Airway diseases are one of the most commonly studied manifestations of IBD. It is observed that populations with pre-existing obstructive pulmonary conditions are at higher risk of new-onset IBD. This newly documented evidence of increased incidence of IBD among patients with pulmonary diseases and the higher than the estimated prevalence of pulmonary diseases among IBD sufferers support the hypothesis of a two-way association. This review article focuses on summarizing the current knowledge and available evidence regarding the association between IBD and obstructive pulmonary diseases such as chronic obstructive pulmonary disease (COPD), emphysema, bronchiectasis, and asthma. We utilized PubMed as the primary search source and database and included the free full-text articles available on it, published over the past five years. We reviewed literature from multiple regions of the world, such as the US, UK, China, and Canada and compiled this traditional review article utilizing the information collected from 4,966,459 patients. Specifications such as age and gender were not mentioned in all articles. This review will serve to strengthen the existing research database concerning the relationship between IBD and obstructive pulmonary diseases. It will help to highlight the significance of the two-way association between IBD and obstructive pulmonary disease and the importance of treating these two conditions simultaneously. It will also raise awareness about the importance of timely detection of IBD and associated airway complications, leading to decreased disease burden and the treatment cost.

Abstract
Tumor necrosis factor-alpha (TNF-α) plays an important role in
autoimmune diseases. Previous studies have investigated the association of
TNF-α-238G/A (rs361525) and -308G/A
(rs1800629) polymorphisms with rheumatoid arthritis (RA) and systemic lupus
erythematosus (SLE). However, no agreed conclusion had been made. Therefore,
this meta-analysis was conducted to assess the associations of
TNF-α-238G/A and -308G/A polymorphisms
with RA and SLE risk. A systematic search was conducted in commonly used
databases. Meta-analysis was performed by STATA12.0. A total of 43 studies were
included. In the overall population, the TNF-α-238A allele was
observed to be a protective factor for RA (A vs G: OR=0.75,
95%CI=0.57–0.99, P=0.040) and the TNF-α-308A allele was found
to be a risk factor for SLE (A vs G: OR=1.78, 95%CI=1.45–2.19,
P<0.001). However, no evidence of association was found between
TNF-α-238 G/A polymorphism and SLE nor between -308G/A and
RA. In the subgroup analysis, TNF-α-308A allele played a
pathogenic role for RA in Latin Americans (A vs G: OR=1.46,
95%CI=1.15–1.84, P=0.002) and for SLE in Latin Americans (A vs
G: OR=2.12, 95%CI=1.32–3.41, P=0.002) and Europeans (A vs G:
OR=2.03, 95%CI=1.56–2.63, P<0.001), while it played a protective role for RA
in Asians (A vs G: OR=0.54, 95%CI=0.32–0.90, P=0.017). No
significant association was found between TNF-α-308G/A and SLE
susceptibility in Africans and Asians. This meta-analysis demonstrated that
TNF-α-238A was associated with decreased risk of RA rather
than SLE, while -308G/A polymorphism was associated with SLE
rather than RA. Stratification analysis indicated that different ethnicities
would have different risk alleles.

Abstract
Co-occurrence of autoimmune diseases (ADs) within an individual is postulated to be a frequent phenomenon in rheumatic diseases. Similar clinical signs and symptoms, pathophysiological mechanisms, genetic factors within autoimmune diseases and aggregation of diverse ADs within families sustain the theory of shared pathogenesis of several ADs (autoimmune tautology). Polyautoimmunity (PA) is defined as the presence of more than one autoimmune disease in a single patient. When three or more autoimmune diseases coexist, this condition is called multiple autoimmune syndrome (MAS). This analysis summarizes an estimated prevalence of PA in the most common rheumatic diseases, the presumable risk factors for PA and influence of concomitant diseases on the course of disease.

Abstract
The incidence of pulmonary manifestations of inflammatory bowel disease (IBD) appears to be much higher than previously assumed. In prospective studies, subclinical pulmonary interstitial infiltrates or pathological lung function were found in 40%-60% of IBD patients, both in children and adults. Pulmonary disorders can affect any part of the respiratory system, the most frequent pattern being inflammation of the large airways often associated with bronchiectasis. The differential diagnosis should include drug-related pulmonary disease and infectious causes when receiving immunosuppressive therapy. The diagnostic approach consists of a thorough history and clinical status as well as lung function tests including body plethysmography and high-resolution computed tomography of the thorax. Bronchoscopy with broncheoalveolar lavage and sample collection for histology as well as exclusion of pulmonary embolism may be indicated. Pulmonary disease in association with IBD can develop at any time during the course of IBD: in rare cases, symptoms can evolve even before gastrointestinal symptoms appear. On the other hand, there are frequent reports on the occurrence of pulmonary inflammation after proctocolectomy in patients with ulcerative colitis. The pathophysiologic background is largely unknown, but there seems to be an interaction between gastrointestinal and pulmonary inflammation. The mainstay of therapy are inhaled or systemic corticosteroids. Most patterns of pulmonary involvement in IBD respond well to corticosteroid therapy. Rarely, serious and persisting complications occur, such as strictures or stenosis of the large airways.

Abstract
There are co-morbidity between osteoporosis (OP) and rheumatoid arthritis (RA). Some genetic risk factors have been identified for these two phenotypes respectively in previous research; however, they accounted for only a small portion of the underlying total genetic variances. Here, we sought to identify additional common genetic loci associated with OP and/or RA. The conditional false discovery rate (cFDR) approach allows detection of additional genetic factors (those respective ones as well as common pleiotropic ones) for the two associated phenotypes. We collected and analyzed summary statistics provided by large, multi-center GWAS studies of FNK (femoral neck) BMD (a major risk factor for osteoporosis) (n = 53,236) and RA (n = 80,799). The conditional quantile-quantile (Q-Q) plots can assess the enrichment of SNPs related to FNK BMD and RA, respectively. Furthermore, we identified shared loci between FNK BMD and RA using conjunction cFDR (ccFDR). We found strong enrichment of p-values in FNK BMD when conditional Q-Q was done on RA and vice versa. We identified 30 novel OP-RA associated pleiotropic loci that have not been reported in previous OP or RA GWAS, 18 of which located in the MHC (major histocompatibility complex) region previously reported to play an important role in immune system and bone health. We identified some specific novel polygenic factors for OP and RA respectively, and identified 30 novel OP-RA associated pleiotropic loci. These discovery findings may offer novel pathobiological insights, and suggest new targets and pathways for drug development in OP and RA patients.

Abstract
Multiple sclerosis (MS) is an autoimmune disease of the central nervous system characterized by brain inflammation, demyelination and axonal loss. Neuropeptide Y (NPY) has a critical role in the maintenance of homeostasis in the immune system and coping of stress condition. In the current study we analyzed 188 patients suffering from MS and 204 unrelated healthy controls for two functional single nucleotide polymorphisms (SNPs), NPY 20T>C (rs16139) and NPY -485T>C (rs16147) using PCR-RFLP and Mismatch PCR-RFLP methods. Our results demonstrated that homozygocity in the minor allele for NPY -485T>C polymorphism is associated with the MS risk in patients in compare with healthy controls (CC vs. TT, P=0.033; CC vs. TT+TC, P=0.02). In addition, by comparison with allele T, the frequency of NPY -485C allele was higher in cases than in control subjects and present increased risk of MS, but statistically significant was borderline (P=0.053). The stratification for disease progression revealed a significant difference in the allelic and genotypic distribution between subgroups of MS and controls. The frequency of the CC genotype and C allele was higher in the primary progressive MS patients when compared with control group (CC vs. TT, P=0.019; CC vs. TT+TC, P=0.008; C vs. T, P=0.022). In addition, the frequency of CC genotype was higher in the relapsing remitting MS patients when compared with control group (CC vs. TT, P=0.034; CC vs. TT+TC, P=0.016). Haplotype analysis demonstrated that the haplotype 3 (CT) is more common in RR MS (P=0.041), and PP MS (P=0.031) than control group. In conclusion, the obtained results demonstrate the probable role of NPY SNPs in susceptibility to MS within the Iranian population.

Abstract
Objective:To assess and compare the frequencies of personal and family history of autoimmune diseases (AID), autoinflammatory disorders (ID), and allergies in a population of patients, adults and children, with narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH), 3 central hypersomnia disorders, and healthy controls.Methods:Personal and family history of AID, ID, and allergies were assessed by questionnaire and medical interview in a large cohort of 450 consecutive adult patients (206 NT1, 106 NT2, 138 IH) and 95 pediatric patients (80 NT1) diagnosed according to the third International Classification of Sleep Disorders criteria in national reference centers for narcolepsy in France and 751 controls (700 adults, 51 children) from the general population.Results:Ten adults with NT1 (4.9%) had a comorbid AID vs 3.4% of adult controls, without between-group differences in adjusted models. AID frequency did not differ between children with NT1 and controls. Conversely, compared with controls, AID frequency was higher in adults with NT2 (p = 0.002), whereas ID (p = 0.0002) and allergy (p = 0.003) frequencies were higher in adults with IH. A positive family history of AID was found in the NT1 group and of ID in the IH group.Conclusions:NT1 is not associated with increased risk of comorbid immune disorders, in favor of a potentially unique pathophysiology. Conversely, compared with controls, the frequency of autoimmune diseases was higher in adults with NT2, whereas allergies and autoinflammatory disorders were more common in adults with IH, suggesting an immune dysregulation mechanism in these conditions.

Abstract
SEE PLUCHINO AND PERUZZOTTI-JAMETTI DOI101093/AWW266 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Myelin regeneration (remyelination) is a spontaneous process that occurs following central nervous system demyelination. However, for reasons that remain poorly understood, remyelination fails in the progressive phase of multiple sclerosis. Emerging evidence indicates that alternatively activated macrophages in central nervous system lesions are required for oligodendrocyte progenitor differentiation into remyelinating oligodendrocytes. Here, we show that an alternatively activated macrophage secreted enzyme, interleukin-four induced one (IL4I1), is upregulated at the onset of inflammation resolution and remyelination in mouse central nervous system lesions after lysolecithin-induced focal demyelination. Focal demyelination in mice lacking IL4I1 or interleukin 4 receptor alpha (IL4Rα) results in increased proinflammatory macrophage density, remyelination impairment, and axonal injury in central nervous system lesions. Conversely, recombinant IL4I1 administration into central nervous system lesions reduces proinflammatory macrophage density, enhances remyelination, and rescues remyelination impairment in IL4Rα deficient mice. We find that IL4I1 does not directly affect oligodendrocyte differentiation, but modulates inflammation by reducing interferon gamma and IL17 expression in lesioned central nervous system tissues, and in activated T cells from splenocyte cultures. Remarkably, intravenous injection of IL4I1 into mice with experimental autoimmune encephalomyelitis at disease onset significantly reversed disease severity, resulting in recovery from hindlimb paralysis. Analysis of post-mortem tissues reveals reduced axonal dystrophy in spinal cord, and decreased CD4+ T cell populations in spinal cord and spleen tissues. These results indicate that IL4I1 modulates inflammation by regulating T cell expansion, thereby permitting the formation of a favourable environment in the central nervous system tissue for remyelination. Therefore, IL4I1 is a potentially novel therapeutic for promoting central nervous system repair in multiple sclerosis.

Abstract
There is a growing recognition of the importance of the commensal intestinal microbiota in the development and later function of the central nervous system. Research using germ-free mice (mice raised without any exposure to microorganisms) has provided some of the most persuasive evidence for a role of these bacteria in gut-brain signalling. Key findings show that the microbiota is necessary for normal stress responsivity, anxiety-like behaviors, sociability, and cognition. Furthermore, the microbiota maintains central nervous system homeostasis by regulating immune function and blood brain barrier integrity. Studies have also found that the gut microbiota influences neurotransmitter, synaptic, and neurotrophic signalling systems and neurogenesis. The principle advantage of the germ-free mouse model is in proof-of-principle studies and that a complete microbiota or defined consortiums of bacteria can be introduced at various developmental time points. However, a germ-free upbringing can induce permanent neurodevelopmental deficits that may deem the model unsuitable for specific scientific queries that do not involve early-life microbial deficiency. As such, alternatives and complementary strategies to the germ-free model are warranted and include antibiotic treatment to create microbiota-deficient animals at distinct time points across the lifespan. Increasing our understanding of the impact of the gut microbiota on brain and behavior has the potential to inform novel management strategies for stress-related gastrointestinal and neuropsychiatric disorders.

Abstract
The objective of this multicentric case-control study was to investigate if a history of autoimmune disease (AD) in first-degree relatives (FDR) is a risk factor for systemic lupus erythematosus (SLE) and to evaluate the risk of AD among FDR of SLE patients. Cases were Italian SLE patients consecutively enrolled. Controls were orthopaedic inpatients without any autoimmune diseases.The strength of the association between family history of AD and SLE was measured as an odds ratio (OR) calculated from the coefficient of an unconditional regression model. To calculate the risk of AD among FDR of SLE patients, the extended generalized estimating equation technique was used. In total, 154 SLE cases and 140 controls were enrolled. A family history of AD was reported by 22.7% of SLE patients and by 5.7% of the controls. The risk of SLE increased with the number of FDR with AD (one FDR affected, OR 4.1; two or more, OR 11.3). The probability of having AD was higher among FDR of SLE cases in comparison to FDR of controls (RR 4.6; 95%CI 1.9-11.1). A female SLE patient conferred an increased risk of AD to her FDR; this risk is doubled in females (OR 10.3; 95% CI 3.1-34.4).

Abstract
Pyogenic Arthritis, Pyoderma gangrenosum, and Acne (PAPA syndrome) is a rare autosomal dominant, auto-inflammatory disease that affects joints and skin. The disease results due to mutations in the cluster of differentiation 2 binding protein 1 (CD2BP1) gene on chromosome 15q24.3. Rheumatoid arthritis (RA) is a common, genetically complex disease that affects the joints with occasional skin manifestations. Studies related to the pathophysiology of inflammation in these two disorders show a certain degree of overlap at genetic level. The present study was done to confirm the existence of such a genetic overlap between PAPA syndrome and RA in south Indian population. In the present study 100 patients who were clinically diagnosed rheumatoid arthritis and 100 apparently healthy controls were chosen and the 15 exons of CD2BP1 gene were PCR-amplified and sequenced. The sequence analysis showed that in exon 3 thirty eight patients revealed presence of novel heterozygous missense mutations p.Glu51Asp, p.Leu57Arg and p.Ala64Thr. In exons 6, 10 and 14 eight patients showed 44 novel missense mutations and two patients showed novel frame shift mutations p.(Met123_Leu416delinsThr) and p.(Thr337Profs*52) leading to truncated protein formation. Such mutations were not seen in controls. Further, the in silico analysis revealed the mutant CD2BP1 structure showed deletion of Cdc15 and SH3 domains when superimposed with the wild type CD2BP1 structure with variable RMSD values. Therefore, these structural variations in CD2BP1 gene due to the mutations could be one of the strongest reasons to demonstrate the involvement of these gene variations in the patients with rheumatoid arthritis.

Abstract
TNF-α antagonists provide benefit to patients with inflammatory autoimmune disorders such as Crohn's disease, rheumatoid arthritis, and ankylosing spondylitis. However, TNF antagonism unexplainably exacerbates CNS autoimmunity, including multiple sclerosis and neuromyelitis optica. The underlying mechanisms remain enigmatic. We demonstrate that TNFR2 deficiency results in female-biased spontaneous autoimmune CNS demyelination in myelin oligodendrocyte glycoprotein-specific 2D2 TCR transgenic mice. Disease in TNFR2(-/-) 2D2 mice was associated with CNS infiltration of T and B cells as well as increased production of myelin oligodendrocyte glycoprotein-specific IL-17, IFN-γ, and IgG2b. Attenuated disease in TNF(-/-) 2D2 mice relative to TNFR2(-/-) 2D2 mice identified distinctive roles for TNFR1 and TNFR2. Oral antibiotic treatment eliminated spontaneous autoimmunity in TNFR2(-/-) 2D2 mice to suggest role for gut microbiota. Illumina sequencing of fecal 16S rRNA identified a distinct microbiota profile in male TNFR2(-/-) 2D2 that was associated with disease protection. Akkermansia muciniphila, Sutterella sp., Oscillospira sp., Bacteroides acidifaciens, and Anaeroplasma sp. were selectively more abundant in male TNFR2(-/-) 2D2 mice. In contrast, Bacteroides sp., Bacteroides uniformis, and Parabacteroides sp. were more abundant in affected female TNFR2(-/-) 2D2 mice, suggesting a role in disease causation. Overall, TNFR2 blockade appears to disrupt commensal bacteria-host immune symbiosis to reveal autoimmune demyelination in genetically susceptible mice. Under this paradigm, microbes likely contribute to an individual's response to anti-TNF therapy. This model provides a foundation for host immune-microbiota-directed measures for the prevention and treatment of CNS-demyelinating autoimmune disorders.

Abstract
Background Multiple sclerosis (MS) is a neurodegenerative, autoimmune disease of the central nervous system. Genome-wide association studies (GWAS) have identified over hundred polymorphisms with modest individual effects in MS susceptibility and they have confirmed the main individual effect of the Major Histocompatibility Complex. Additional risk loci with immunologically relevant genes were found significantly overrepresented. Nonetheless, it is accepted that most of the genetic architecture underlying susceptibility to the disease remains to be defined. Candidate association studies of the leukocyte immunoglobulin-like receptor LILRA3 gene in MS have been repeatedly reported with inconsistent results. Objectives In an attempt to shed some light on these controversial findings, a combined analysis was performed including the previously published datasets and three newly genotyped cohorts. Both wild-type and deleted LILRA3 alleles were discriminated in a single-tube PCR amplification and the resulting products were visualized by their different electrophoretic mobilities. Results and Conclusion Overall, this meta-analysis involved 3200 MS patients and 3069 matched healthy controls and it did not evidence significant association of the LILRA3 deletion [carriers of LILRA3 deletion: p = 0.25, OR (95% CI) = 1.07 (0.95–1.19)], even after stratification by gender and the HLA-DRB1*15:01 risk allele.

Genome wide identification of new genes and pathways in patients with both autoimmune thyroiditis and type 1 diabetes. J Autoimmun 2015; 60:32-9.

Abstract
Autoimmune thyroid diseases (AITD) and Type 1 diabetes (T1D) frequently occur in the same individual pointing to a strong shared genetic susceptibility. Indeed, the co-occurrence of T1D and AITD in the same individual is classified as a variant of the autoimmune polyglandular syndrome type 3 (designated APS3v). Our aim was to identify new genes and mechanisms causing the co-occurrence of T1D + AITD (APS3v) in the same individual using a genome-wide approach. For our discovery set we analyzed 346 Caucasian APS3v patients and 727 gender and ethnicity matched healthy controls. Genotyping was performed using the Illumina Human660W-Quad.v1. The replication set included 185 APS3v patients and 340 controls. Association analyses were performed using the PLINK program, and pathway analyses were performed using the MAGENTA software. We identified multiple signals within the HLA region and conditioning studies suggested that a few of them contributed independently to the strong association of the HLA locus with APS3v. Outside the HLA region, variants in GPR103, a gene not suggested by previous studies of APS3v, T1D, or AITD, showed genome-wide significance (p < 5 × 10(-8)). In addition, a locus on 1p13 containing the PTPN22 gene showed genome-wide significant associations. Pathway analysis demonstrated that cell cycle, B-cell development, CD40, and CTLA-4 signaling were the major pathways contributing to the pathogenesis of APS3v. These findings suggest that complex mechanisms involving T-cell and B-cell pathways are involved in the strong genetic association between AITD and T1D.

Abstract
The objective of the study was to assess whether the incidences of Crohn's disease and ulcerative colitis are increased in patients with asthma and chronic obstructive pulmonary disease (COPD) compared to the general population. A population-based retrospective cohort study was conducted using the administrative health databases of Québec, Canada. Incidences of Crohn's disease and ulcerative colitis among patients with asthma and COPD were assessed for the 2001-2006 period. In total, 136 178 subjects with asthma and 143 904 subjects with COPD were identified. The average incidence of Crohn's disease and ulcerative colitis was 23.1 and 8.8 per 100 000 person-years among asthmatic patients; in the COPD cohort there were 26.2 Crohn's disease cases and 17 ulcerative colitis cases per 100 000 person-years. The incidence of Crohn's disease in asthma and COPD patients was 27% and 55% higher than in the general population of Québec; the incidence of ulcerative colitis was 30% higher among COPD patients compared to the general population. Incidence of inflammatory bowel disease was significantly increased in asthma and COPD patients compared to the general population of Québec. Incidence rates were particularly high in patients with COPD. Awareness of an association between airway diseases and inflammatory bowel disease in older age groups may play an important role in earlier detection of bowel disease and in the therapeutic management of such patients.

Abstract
The search for genetic determinants of alloimmunization in sickle cell disease transfusion recipients was based on two premises: i) that polymorphisms responsible for stronger immune and/or inflammatory responses and hemoglobin β(S) mutation were co-selected by malaria; and ii) that stronger responder status contributes to development of lupus. We found a marker of alloimmunization in the gene encoding for Ro52 protein, also known as Sjögren syndrome antigen 1 (SSA1) and TRIM21. Surprisingly, the nature of the association was opposite of that with lupus; the same variant of a polymorphism (rs660) that was associated with lupus incidence was also associated with induction of tolerance to red blood cell antigens during early childhood. The dual function of Ro52 can explain this apparent contradiction. We propose that other lupus/autoimmunity susceptibility loci may reveal roles of additional molecules in various aspects of alloimmunization induced by transfusion as well as during pregnancy.

Abstract
T cells are critically dependent on cellular proliferation in order to carry out their effector functions. Autoimmune strains are commonly thought to have uncontrolled T cell proliferation; however, in the murine model of autoimmune diabetes, hypo-proliferation of T cells leading to defective AICD was previously uncovered. We now determine whether lupus prone murine strains are similarly hyporesponsive. Upon extensive characterization of T lymphocyte activation, we have observed a common feature of CD4 T cell activation shared among three autoimmune strains-NOD, MRL, and NZBxNZW F1s. When stimulated with a polyclonal mitogen, CD4 T cells demonstrate arrested cell division and diminished dose responsiveness as compared to the non-autoimmune strain C57BL/6, a phenotype we further traced to a reliance on B cell mediated costimulation, which underscores the success of B cell directed immune therapies in preventing T cell mediated tissue injury. In turn, the diminished proliferative capacity of these CD4 T cells lead to a decreased, but activation appropriate, susceptibility to activation induced cell death. A similar decrement in stimulation response was observed in the CD8 compartment of NOD mice; NOD CD8 T cells were distinguished from lupus prone strains by a diminished dose-responsiveness to anti-CD3 mediated stimulation. This distinction may explain the differential pathogenetic pathways activated in diabetes and lupus prone murine strains.

Abstract
Autoimmune diseases are a range of diseases in which the immune response to self-antigens results in damage or dysfunction of tissues. Autoimmune diseases can be systemic or can affect specific organs or body systems. For most autoimmune diseases there is a clear sex difference in prevalence, whereby females are generally more frequently affected than males. In this review, we consider gender differences in systemic and organ-specific autoimmune diseases, and we summarize human data that outlines the prevalence of common autoimmune diseases specific to adult males and females in countries commonly surveyed. We discuss possible mechanisms for sex specific differences including gender differences in immune response and organ vulnerability, reproductive capacity including pregnancy, sex hormones, genetic predisposition, parental inheritance, and epigenetics. Evidence demonstrates that gender has a significant influence on the development of autoimmune disease. Thus, considerations of gender should be at the forefront of all studies that attempt to define mechanisms that underpin autoimmune disease.

Abstract
Evidence suggests that autoimmune diseases tend to co-occur so that patients with an autoimmune disorder are at higher risk of a second autoimmune disease. The association between allergic and autoimmune diseases is also of considerable interest. There are no reports on the association between sporadic or familial narcolepsy with cataplexy and other non-neurological immune-mediated diseases. This study reported on the comorbid immunopathological diseases associated with narcolepsy. One-hundred and fifty six narcoleptic patients with a mean age at diagnosis of 39.1 ± 17.8 years (range, 6-70 years) were assessed using the clinical history, physical and neurological examinations, sleep questionnaires, neuroimaging and human leucocyte antigen typing. Diagnosis was confirmed by polysomnography followed by a multiple sleep latency test or by measuring hypocretin-1 levels. Patients with immunopathological diseases were matched for gender and age at the onset of narcoleptic symptoms with narcoleptic patients without immunopathological diseases. Twenty-six patients (16.6%; 50% women; one familial, 25 sporadic) had one or more immunopathological diseases associated: autoimmune diseases, such as idiopathic thrombocytopenic purpura, multiple sclerosis, systemic lupus erythematosus, psoriasis, Crohn's disease, ulcerative colitis, autoimmune thyroid disease, Peyronie's disease and idiopathic recurrent facial palsy; other immunopathological diseases, like atopic dermatitis, allergic asthma and allergic rhinitis. Although not significant, the age at diagnosis of narcolepsy was 9.3 years earlier in patients with narcolepsy + immunopathological diseases. The results demonstrate that the prevalence of comorbid immunopathological diseases is high in narcolepsy, and cataplexy is significantly more severe in patients with narcolepsy + immunopathological diseases.

Abstract
Type 1 diabetes (T1D) is an autoimmune disease (AID) with both genetic and environmental components. We aimed to investigate the genetic association of polymorphisms in genes previously linked with other AIDs, namely BANK1, IL15 and IL2/IL21 region. A total of 76 T1D patients and 162 controls from Southern Tunisia were recruited for a case-control association study investigating the relationship between sixteen SNPs of the BANK1, IL15 and IL2/IL21 gene region and T1D. In the BANK1 gene, G allele and GG genotype of rs3733197 were significantly increased in the group of T1D patients compared to controls. In addition, in the IL15 gene, the minor allele A of rs10519613 polymorphism was significantly higher in patients than in controls. No significant association was found for SNPS in IL2/IL21 gene region. The analysis of the haplotype structure revealed the G-C-A-C-T haplotype of the IL15 gene as associated with a reduction in the risk of developing T1D, while A-T-A-C-T haplotype increased the risk of developing the disease. Furthermore, in the IL2/IL21 region, only one haplotype consisting of eight SNPs was markedly associated with T1D susceptibility. Moreover, G-C combination of the BANK1/IL15 was significantly increased in T1D patients, compared to controls. Our results establish BANK1 and IL15 as new T1D genetic susceptibility factors and replicate the association of the 4q27 region with T1D. Our data agree with the effect previously observed for other autoimmune conditions and delineate a shared underlying mechanism.

Abstract
OBJECTIVE. IRF5, TLR4, DEFB1, and VDR genetic variations have been associated with ulcerative colitis (UC) in several European patient cohorts. As distinct genetic backgrounds may play a role in different ethnicities, we evaluated the effects of single-nucleotide polymorphisms (SNPs) in these genes and their interactions in UC patients of Han Chinese descent. MATERIAL AND METHODS. DNA samples from 300 UC patients and 302 healthy control subjects from Peking Union Medical College Hospital were genotyped for 14 tag SNPs, which were selected based on haplotype analysis of IRF5, TLR4, DEFB1, and VDR. Multidimensionality reductions were used to explore gene-gene interactions. RESULTS. The only observed association with UC was for IRF5. On an allelic level, SNP rs3807306 was associated with UC risk (p = 6.7 × 10(-3)). On a genotypic level, the CC genotype of SNP rs3807306 (p = 0.03) was associated with protection from UC, and the AA genotype of SNP rs4728142 (p = 7.6 × 10(-3)) was associated with a risk of UC. In the haplotype analysis, GGATT was highly correlated with UC risk (p-Value = 2.0 × 10(-4)). No significant multilocus interactions were detected among these four genes. CONCLUSIONS. Our study confirmed the association of IRF5 with UC in Han Chinese patients. Han Chinese UC patients share part of their genetic susceptibility with Caucasian patients.

Abstract
Clinical pathologies draw us to envisage disease as either an independent entity or a diverse set of traits governed by common physiopathological mechanisms, prompted by environmental assaults throughout life. Autoimmune diseases are not an exception, given they represent a diverse collection of diseases in terms of their demographic profile and primary clinical manifestations. Although they are pleiotropic outcomes of non-specific disease genes underlying similar immunogenetic mechanisms, research generally focuses on a single disease. Drastic technologic advances are leading research to organize clinical genomic multidisciplinary approaches to decipher the nature of human biological systems. Once the currently costly omic-based technologies become universally accessible, the way will be paved for a cleaner picture to risk quantification, prevention, prognosis and diagnosis, allowing us to clearly define better phenotypes always ensuring the integrity of the individuals studied. However, making accurate predictions for most autoimmune diseases is an ambitious challenge, since the understanding of these pathologies is far from complete. Herein, some pitfalls and challenges of the genetics of autoimmune diseases are reviewed, and an approximation to the future of research in this field is presented.

The association of CD81 polymorphisms with alloimmunization in sickle cell disease. Clin Dev Immunol 2013; 2013:937846.

Abstract
The goal of the present work was to identify the candidate genetic markers predictive of alloimmunization in sickle cell disease (SCD). Red blood cell (RBC) transfusion is indicated for acute treatment, prevention, and abrogation of some complications of SCD. A well-known consequence of multiple RBC transfusions is alloimmunization. Given that a subset of SCD patients develop multiple RBC allo-/autoantibodies, while others do not in a similar multiple transfusional setting, we investigated a possible genetic basis for alloimmunization. Biomarker(s) which predicts (predict) susceptibility to alloimmunization could identify patients at risk before the onset of a transfusion program and thus may have important implications for clinical management. In addition, such markers could shed light on the mechanism(s) underlying alloimmunization. We genotyped 27 single nucleotide polymorphisms (SNPs) in the CD81, CHRNA10, and ARHG genes in two groups of SCD patients. One group (35) of patients developed alloantibodies, and another (40) had no alloantibodies despite having received multiple transfusions. Two SNPs in the CD81 gene, that encodes molecule involved in the signal modulation of B lymphocytes, show a strong association with alloimmunization. If confirmed in prospective studies with larger cohorts, the two SNPs identified in this retrospective study could serve as predictive biomarkers for alloimmunization.

Abstract
A regulatory single nucleotide polymorphism located in the 5' region (-169T/C) of the Fc receptor-like 3 (FCRL3_3) gene has been associated with both susceptibility and protection in immune diseases. This case-control study aimed to evaluate the association between FCRL3 polymorphisms and juvenile rheumatoid arthritis (JRA), asthma, and childhood-onset systemic lupus erythematosus (SLE) in a Mexican population. We performed PCR-based genotyping to identify four FCRL3 single nucleotide polymorphisms (FCRL3_3 to FCRL3_6) in patients with JRA (n=202), asthma (n=239), or childhood-onset SLE (n=377), and healthy controls (n=400). The case-control analysis showed a male-gender dependent association between the FCRL3_3C, FCRL3_5C, and FCRL3_6A alleles and either JRA (OR=0.57, p=0.003; OR=0.55, p=0.002; OR=0.53, p=0.0007, respectively) or asthma (OR=0.72, p=0.04; OR=0.74, p=0.05; OR=0.70, p=0.02, respectively). As expected, minor alleles of these SNPs with the CGCA haplotype were also significantly associated with JRA (OR=0.35, p=0.00005) and asthma (OR=0.61, p=0.007). We found no association between FCRL3 SNPs or haplotypes and childhood-onset SLE. These results supported the notion that FCRL3 is involved in the etiology of several immune diseases. Our results also suggested that SNPs located in the FCRL3 gene were protective against JRA and asthma in male Mexican patients.

Abstract
OBJECTIVE Cia3 is a locus on rat chromosome 4 that regulates severity and joint damage in collagen- and pristane-induced arthritis (CIA and PIA). This study was undertaken to refine the Cia3 gene-containing interval toward gene identification and obtain insights into its mode of action. METHODS Five DA.F344(Cia3) subcongenic rat strains were generated and studied using the PIA and CIA models. Levels of antibodies against type II collagen (both allo- and autoantibodies) were measured. Joints and synovial tissue were collected 32 days after the induction of PIA (chronic stage) for histologic and quantitative polymerase chain reaction analysis of interleukin-1β (IL-1β) and matrix metalloproteinase (MMP) levels. RESULTS Three subcongenic strains sharing the centromeric Cia3d interval were protected and 2 subcongenic strains sharing the telomeric Cia3g interval, which did not overlap with Cia3d, were also protected, developing significantly less severe CIA and PIA. Normal joint architecture was preserved in DA.F344(Cia3) and DA.F344(Cia3d) congenic rats with PIA, while DA rats had pronounced synovial hyperplasia, angiogenesis, inflammatory infiltration, and bone or cartilage erosions. The DA.F344(Cia3d) and DA.F344(Cia3g) strains had significantly lower synovial levels of IL-1β (5-fold and nearly 2-fold, respectively [the latter not reaching statistical significance]), MMP-1 (expressed predominantly in DA rats), MMP-3 (79-fold and 8-fold, respectively), and MMP-14 (21-fold and 1.4-fold, respectively) and reduced levels of pathogenic autoantibodies against type II collagen, compared with DA rats. CONCLUSION We have identified 2 new arthritis severity and articular damage loci within Cia3. These loci regulate pathogenic processes in 2 different models of rheumatoid arthritis, and the identification of these genes has the potential to generate new targets for therapies aimed at reducing disease severity and articular damage, and may additionally have prognostic value.

Abstract
Psoriasis is a common, inflammatory, chronic, relapsing skin disease. New insight about the etiology of this disease shows the important role played by the epidermal barrier function, its integrity and pathogen responses in combination with microbial environmental factors. A pivotal role in the management of this balance is played by NLR genes, also known as NBD-LRR or CATERPILLER, that encode important mediators of innate immunity and provide the first line of defense against pathogens. The polymorphism of these genes is implicated in the pathogenesis of several immunological diseases and might be of importance in the pathogenesis of barrier organ disorders. Crohn's disease is considered archetypal of these kinds of disorders; similarities between Crohn's disease and psoriasis and their similar pathogenetic mechanisms may support the concept of psoriasis as a barrier organ disorder and common genetic ground lying behind these illnesses. Considering psoriasis as a "barrier organ disease" is not only a mere mental exercise; this consideration may, in fact, open new prospects in the treatment of these disorders just by preventing alterations of microbial flora or regulating the response of the host to infective diseases.

Abstract
Male bias in both autism and pediatric autoimmune disease is thought to involve hormonal perturbations in pregnancy or early childhood in the context of genetic control. These early molecular events, at a time of rapid development, are intimately linked to concurrent development in the brain and immune system. It is suggested here that these early regulatory events may overlap between autism and autoimmunity in determining male sex bias and may provide evidence of an etiological link among autism, immune dysregulation, and autoimmune disease.

Abstract
Experimental autoimmune encephalomyelitis (EAE) is a widely used model of multiple sclerosis. In NOD mice, EAE develops as a relapsing-remitting disease that transitions to a chronic progressive disease, making the NOD model the only mouse model that recapitulates the full clinical disease course observed in most multiple sclerosis patients. We have generated a TCR transgenic mouse that expresses the α- and β-chains of a myelin oligodendrocyte glycoprotein (MOG) 35-55-reactive TCR (1C6) on the NOD background. 1C6 TCR transgenic mice spontaneously generate both CD4(+) and CD8(+) T cells that recognize MOG and produce proinflammatory cytokines, allowing for the first time to our knowledge the simultaneous examination of myelin-reactive CD4(+) and CD8(+) T cells in the same host. 1C6 CD8(+) T cells alone can induce optic neuritis and mild EAE with delayed onset; however, 1C6 CD4(+) T cells alone induce severe EAE and predominate in driving disease when both cell types are present. When 1C6 mice are crossed with mice bearing an IgH specific for MOG, the mice develop spontaneous EAE with high incidence, but surprisingly the disease pattern does not resemble the neuromyelitis optica-like disease observed in mice bearing CD4(+) T cells and B cells reactive to MOG on the C57BL/6 background. Collectively, our data show that although myelin-reactive CD8(+) T cells contribute to disease, disease is primarily driven by myelin-reactive CD4(+) T cells and that the coexistence of myelin-reactive T and B cells does not necessarily result in a distinct pathological phenotype.

Abstract
Autologous hematopoietic stem cell transplantation (aHSCT) has been used as a therapeutic approach in multiple sclerosis (MS). However, it is still unclear if the immune system that emerges from autologous CD34+ hematopoietic progenitor cells (HPC) of MS patients is pre-conditioned to re-develop the proinflammatory phenotype. The objective of this article is to compare the whole genome gene and microRNA expression signature in CD34+ HPC of MS patients and healthy donors (HD). CD34+ HPC were isolated from peripheral blood of eight MS patients and five HD and analyzed by whole genome gene expression and microRNA expression microarray. Among the differentially expressed genes (DEGs) only TNNT1 reached statistical significance (logFC=3.1, p<0.01). The microRNA expression was not significantly different between MS patients and HD. We did not find significant alterations of gene expression or microRNA profiles in CD34+ HPCs of MS patients. Our results support the use of aHSCT for treatment of MS.

Abstract
In spite of the well-known clustering of multiple autoimmune disorders in families, analyses of specific shared genes and polymorphisms between systemic lupus erythematosus (SLE) and other autoimmune diseases (ADs) have been limited. Therefore, we comprehensively tested autoimmune variants for association with SLE, aiming to identify pleiotropic genetic associations between these diseases. We compiled a list of 446 non–Major Histocompatibility Complex (MHC) variants identified in genome-wide association studies (GWAS) of populations of European ancestry across 17 ADs. We then tested these variants in our combined Caucasian SLE cohorts of 1,500 cases and 5,706 controls. We tested a subset of these polymorphisms in an independent Caucasian replication cohort of 2,085 SLE cases and 2,854 controls, allowing the computation of a meta-analysis between all cohorts. We have uncovered novel shared SLE loci that passed multiple comparisons adjustment, including the VTCN1 (rs12046117, P = 2.02×10−06) region. We observed that the loci shared among the most ADs include IL23R, OLIG3/TNFAIP3, and IL2RA. Given the lack of a universal autoimmune risk locus outside of the MHC and variable specificities for different diseases, our data suggests partial pleiotropy among ADs. Hierarchical clustering of ADs suggested that the most genetically related ADs appear to be type 1 diabetes with rheumatoid arthritis and Crohn's disease with ulcerative colitis. These findings support a relatively distinct genetic susceptibility for SLE. For many of the shared GWAS autoimmune loci, we found no evidence for association with SLE, including IL23R. Also, several established SLE loci are apparently not associated with other ADs, including the ITGAM-ITGAX and TNFSF4 regions. This study represents the most comprehensive evaluation of shared autoimmune loci to date, supports a relatively distinct non–MHC genetic susceptibility for SLE, provides further evidence for previously and newly identified shared genes in SLE, and highlights the value of studies of potentially pleiotropic genes in autoimmune diseases. It is well known that multiple autoimmune disorders cluster in families. However, all of the genetic variants that explain this clustering have not been discovered, and the specific genetic variants shared between systemic lupus erythematosus (SLE) and other autoimmune diseases (ADs) are not known. In order to better understand the genetic factors that explain this predisposition to autoimmunity, we performed a comprehensive evaluation of shared autoimmune genetic variants. First we considered results from 17 ADs and compiled a list with 446 significant genetic variants from these studies. We identified some genetic variants extensively shared between ADs, as well as the ADs that share the most variants. The genetic overlap between SLE and other ADs was modest. Next we tested how important all the 446 genetic variants were in our collection with a minimum of 1,500 SLE patients. Among the most significant variants in SLE, the majority had already been identified in previous studies, but we also discovered variants in two important immune genes. In summary, our data identified diseases with common genetic risk factors and novel SLE effects, and this supports a relatively distinct genetic susceptibility for SLE. This study helps delineate the genetic architecture of ADs.

Abstract
BACKGROUND The aim of this paper was to examine the prevalence of immune-related disorders in families of children with inflammatory bowel disease (IBD) compared to those without IBD. METHODS Children ≤18 years of age presenting to the IBD clinic between September 2007 and August 2009 with an established diagnosis of IBD were recruited. Age and sex matched controls without IBD were recruited. The study was a single-centre prospective cohort study. Outcome measures were prevalence of immune-based/inflammatory diseases in families of both patients and controls. RESULTS One hundred and eight children in each group were recruited. Asthma was the most frequently reported disease in families of the IBD patients (52.8%) and controls (46.3%). The prevalence of IBD in families of IBD patients was significantly higher than in those without IBD (OR 2.03, 95% CI 1.04-3.95). CONCLUSIONS The prevalence of immune-based disorders, as a group, in families of children with IBD was not significantly higher when compared to children without IBD.

Abstract
BACKGROUND Exacerbation of asthma symptoms due to aspirin ingestion may lead to life-threatening lung failure. The adhesion molecule CD58 gene may play a crucial role in aspirin-exacerbated respiratory disease (AERD) pathogenesis by mediating the biological functions of asthma-inducing mechanisms including T helper cells, proinflammatory cytokines, and natural killer T cells. OBJECTIVE This study aimed to investigate the association of CD58 variations with aspirin-induced bronchospasm in Korean asthma patients. METHODS Seven single-nucleotide polymorphisms were selected for genotyping based on previously reported polymorphisms in the International HapMap database. Genotyping was carried out using TaqMan assay and 2 major haplotypes were obtained in 163 AERD cases and 429 aspirin-tolerant asthma controls. Frequency distributions of CD58 variations were analyzed using logistic and regression models. RESULTS Results showed that none of the analyzed CD58 single-nucleotide polymorphisms and haplotypes was significantly associated with AERD development and fall rate of FEV(1) by aspirin provocation, an important diagnostic marker of aspirin hypersensitivity. CONCLUSIONS This preliminary study suggests that CD58 does not affect AERD susceptibility in a Korean population, and may provide a new direction for future disease etiology.

Abstract
Non-Hodgkin lymphoma (NHL) is a hematological malignancy of the immune system, and, as with autoimmune and inflammatory diseases (ADs), is influenced by genetic variation in the major histocompatibility complex (MHC). Persons with a history of specific ADs also have increased risk of NHL. As the coexistence of ADs and NHL could be caused by factors common to both diseases, here we examined whether some of the associated genetic signals are shared. Overlapping risk loci for NHL subytpes and several ADs were explored using data from genome-wide association studies. Several common genomic regions and susceptibility loci were identified, suggesting a potential shared genetic background. Two independent MHC regions showed the main overlap, with several alleles in the human leukocyte antigen (HLA) class II region exhibiting an opposite risk effect for follicular lymphoma and type I diabetes. These results support continued investigation to further elucidate the relationship between lymphoma and autoimmune diseases.

Abstract
Multiple sclerosis (MS) is a one of the group of diseases labeled as "common complex". Virtually all common complex traits, genetic and environmental components have important roles, both independently and interactively, in disease susceptibility and stochastic and epigenetic effects cannot be overlooked. Data presented are largely part of the Canada-wide prospective, population-based longitudinal Canadian Collaborative Project on Genetic Susceptibility to MS (CCPGSMS) which includes over 30,000 unique families having at least 1 member with MS. Findings do not support a general propensity to autoimmune disease in MS families, but clearly highlight the importance of controlling for gender (patient, informant) when conducting such studies. The MHC class II association has been fine-mapped to the HLA-DRB5*0101-HLA-DRB1*1501-HLA-DQA1*0102-HLA-DQB1*0602 extended haplotype. This HLA haplotype confers a relative risk of approximately 3 and homozygosity for this haplotype increases the risk by over 6 fold. However, the HLA haplotype loci interactions are complex and include, epistasis, trans and cis effects, and parent-of-origin effects. As well, there may be interactions of EBV and vitamin D with the HLA, In conclusion, using MS as an example, susceptibility for common complex disease most likely results from interactions of genes, environmental interactions and gene/environment interactions.

Abstract
The aim of our meta-analysis was to quantitatively summarize the association of TYK2 gene polymorphisms with autoimmune and inflammatory diseases. 11 studies that included data from 21497 cases and 22647 controls were identified. OR was used as a measure of the effect of the association in a fixed/random effect model. Meta-analysis was performed for six TYK2 gene polymorphisms (rs34536443, rs2304256, rs280523, rs280519, rs12720270 and rs12720356). Significant association was found in rs34536443 (C versus G: OR = 0.76, 95% CI = 0.69-0.84, P < 0.00001; GC + CC versus GG: OR = 0.78, 95% CI = 0.68-0.90, P = 0.0005; CC versus GG + GC: OR = 0.76, 95% CI = 0.28-2.05, P = 0.58; CC versus GG: OR = 0.74, 95% CI = 0.27-2.02, P = 0.56; GC versus GG: OR = 0.78, 95% CI = 0.68-0.90, P = 0.0006) and rs2304256 (A versus C: OR = 0.78, 95% CI = 0.70-0.87, P < 0.0001; CA + AA versus CC: OR = 0.69, 95% CI = 0.59-0.81, P < 0.0001; AA versus CC + CA: OR = 0.75, 95% CI = 0.66-1.00, P = 0.05; AA versus CC: OR = 0.64, 95% CI = 0.47-0.86, P = 0.003; CA versus CC: OR = 0.70, 95% CI = 0.60-0.83, P < 0.0001) in TYK2 gene, but not for the other polymorphisms (rs280523, rs280519, rs12720270, and rs12720356). This meta-analysis demonstrates that autoimmune and inflammatory diseases is associated with TYK2 gene rs34536443 and rs2304256 polymorphisms, but not rs280523, rs280519, rs12720270 and rs12720356.
