Abstract
Family history of rheumatoid arthritis (RA) is a proxy for an individual's genetic and, in part, environmental risk of developing RA, and is a well-recognized predictor of disease onset. Although family history of RA is an old concept, the degree of familial aggregation of RA, whether it differs by age, sex, or serology, and what value it has for clinical decisions once a diagnosis of RA has been made remain unclear. New data have been emerging in parallel to substantial progress made in genetic association studies. In this Review, we describe the various ways that familial aggregation has been measured, and how the findings from these studies, whether they are based on twins, cohorts of first-degree relatives, or genetic data, correspond to each other and aid understanding of the aetiology of RA. In addition, we review the potential usefulness of family history of RA from a clinical point of view, demonstrating that, in the era of big data and genomics, family history still has a role in directing clinical decision-making and research.

Abstract
OBJECTIVE To compare Juvenile Idiopathic Arthritis (JIA) patients with and without family history of autoimmune disease with respect to clinical features and laboratory data. METHODS Sixteen JIA patients with family history of autoimmune disease were identified during study, 32 patients were chosen for comparative group from referred patients to the rheumatology clinic according to the date of referral. Two groups were compared with respect to age of onset, sex, subtype, disease activity, duration of active disease and laboratory variables. FINDINGS The age of onset was significantly lower in JIA patients with family history of autoimmunity (4.7 years vs. 7.0 years; P=0.02), polyarthicular subtype was more frequent in patients with positive family history (50% vs.25%; P=0.04) most of JIA patients with positive family history were in the active phase at the time of study (64% vs 25%; P=0.02) and had a longer duration of active disease (21.0 months vs 12.3 months; P=0.04). Patients with positive family history had more positive ANA (43.5%% vs 12.5%; P=0.01) and also more positive ADA (75% vs 20.8%; P=0.002). Two groups were similar according to sex, and other laboratory variables. CONCLUSION JIA patients with family history of autoimmune disease seem to have a more severe disease than patients without such family history, they are younger at the onset, and have mostly poyarthicular subtype. They also have more ANA and ADA positivity. These findings are different from familial JIA case-control studies according to active disease duration, subtype, and ANA positivity.

Distribution of HLA-DRβ1 alleles among well-characterized rheumatoid arthritis patients from Western India. Rheumatol Int 2013; 34:705-8.

Abstract
An association between human leukocyte antigen-DRβ1*04 and rheumatoid arthritis (RA) has been known for more than 25 years. It has been observed in many different populations, and it accounts for approximately one-third of the genetic component of RA susceptibility. Our aim was to study the distribution of HLA-DRβ1 alleles in well-characterized RA patients from Western India. Polymerase chain reaction-based sequence-specific oligonucleotide probing (PCR-SSOP) technique was used to identify HLA-DRβ1 alleles among 80 clinically well-defined patients and 90 normal controls from same ethnicity. A significant increase in the frequency of DRβ1*04 was observed among RA patients (PF% 30 vs. 7.7, OR 4.959, p value 0.00018), whereas DRβ1*03 and *14 were significantly decreased among patients when compared with controls (DRβ1*03, PF% 8.75 vs. 26.6, OR 0.2637, p value 0.00253; DRβ1*14, PF% 17.5 vs. 30.0, OR 0.4949, p value 0.05722). Our results suggest that DRβ1*04 was strongly associated with well-characterized RA patients from Western India, whereas DRβ1*03 and *14 may be protective alleles for RA. The identification of susceptible allele in patients with RA may help physician to make early decisions regarding initiation of early intensive therapy with disease modifying anti-rheumatic drugs and biological agents to decrease disability in RA patients.

Abstract
A strong association between rheumatoid arthritis (RA) and human leukocyte antigen (HLA) has been observed in many different populations and that accounts for approximately one-third of the genetic component of RA susceptibility. The greatest effect comes from DRβ1 gene where the strongest association has been found with DRβ1*04 (DR4) allele. As serology has some disadvantages over polymerase chain reaction (PCR)-based techniques and commercially available PCR-based kits are expensive, this study was aimed to standardize simple in-house PCR-SSP technique. Accuracy of this test was further checked with standard PCR-SSOP (RLS) results. The frequency HLA-DRβ1*04 was significantly increased among RA patients when compared with normal controls. In this study, a very simple, convenient and more cost-effective in-house PCR-SSP technique was standardized for HLA-DRβ1*04 typing that is helpful to RA diagnosis in developing countries like India, which can be used as a good screening test.

Abstract
BACKGROUND The familial clustering of rheumatoid arthritis (RA) in first and second degree relatives of patients supports the role of genetic factors. The proportion of heredity in its development is roughly 60%; however, most individuals closely related to someone with RA do not get the disease. Considering the lack of sufficient data on the familial aggregation of RA in Iran, we designed this study for clarifying the familial prevalence of RA. OBJECTIVE To determine the prevalence of RA among relatives of patients with RA and to evaluate the mean disease onset age in relatives. METHODS In a longitudinal study from July 2008 to July 2010, we followed 210 unrelated patients with RA and their first and second degree relatives (FDR+ and SDR+), by interviewing and physical examination of those with symptoms, to ascertain prevalence. Familial RA was defined by presence of at least two siblings fulfilling the 1987 ACR criteria for RA. RESULTS We demonstrated that 17.6% of patients have at least one affected relative. The prevalence of RA in the family of studied patients was 0.83% (42 people). Thirty-two in FDR+ and 10 people in SDR+ (2.53% and 0.26% of all family), also 1.12% in female relatives and 0.39% in male relatives had RA. The odds ratio for FDR/SDR was 2.52. The mean age at disease onset in relatives was 42.30 ± 1.51 years in FDR+ and 34.40 ± 2.10 years in the SDR+ group (0.03). CONCLUSION The risk of RA is greatest in FDR+ and is likely to be due to a combination of inherited and environmental factors.

Abstract
Rheumatoid arthritis (RA) is a multifactorial disease due to a combination of genetic and environmental factors. Identification of the genetic factors involved in the pathogenesis of RA should open up avenues for developing radical treatment strategies directed at the cause of the disease. The Association de Recherche sur la Polyarthrite (ARP) supports research in this field, in which our group has been involved since 1993. Thanks to this support, considerable progress has been made. Several combinations of susceptibility alleles of various genes are probably involved in the development of RA. Although HLA-DRB1 is the main RA gene, it accounts for only part of the familial risk for RA. HLA-DRB1 alleles are neither necessary nor sufficient to cause the development of RA in a given individual. Several genome scans conducted in populations from France, Japan, North America and UK have confirmed the role of the HLA region and suggested several other susceptibility loci. Association studies support a role for several genes, including TNFR2, PADI4, SLC22A4, RUNX1, and PTPN22. However, the imperfect matching of cases and controls requires that confirmation of these results be obtained. To confirm that a gene confers susceptibility to RA, the association must be replicated in several independent studies and, more importantly, evidence of genetic linkage must be obtained in family studies. The identification of genetic factors conferring susceptibility to RA will open up new avenues toward radical treatments for RA and may help to optimize the diagnostic, prognostic, and pharmacogenetic management of today's patients with RA.

Abstract
OBJECTIVES To elucidate the contribution of HLA-DR-DQ haplotypes and their genotypic combinations to susceptibility to rheumatoid arthritis, and to evaluate the various models for HLA associated risk for the disease in a series of Finnish patients. METHODS 322 Finnish patients with rheumatoid arthritis were typed for common north European HLA-DR-DQ haplotypes and compared with a series of 1244 artificial family based control haplotypes. RESULTS The association of the so called shared epitope (SE) haplotypes (DRB1*0401, *0404, *0408, and *01) with rheumatoid arthritis was confirmed. The DRB1*0401 haplotypes carried a far stronger risk for the disease than the (DRB1*01/10)-(DQA1*01)-DQB1*0501 haplotypes. Seven protective HLA haplotypes--(DRB1*15)-(DQA1*01)-DQB1*0602; (DRB1*08)-(DQA1*04)-DQB1*04; (DRB1*11/12)-DQA1*05-DQB1*0301; (DRB1*1301)-(DQA1*01)-DQB1*0603; (DRB1*1302)-(DQA1*01)-DQB1*0604; (DRB1*07)-DQA1*0201-DQB1*0303; and (DRB1*16)- (DQA1*01)-DQB1*0502--were identified. In accordance with the reshaped shared epitope hypothesis, all the protective DRB1 alleles in these haplotypes share either isoleucine at position 67 or aspartic acid at position 70 in their third hypervariable region motif. However, differences in the disease risk of haplotypes carrying the same DR but different DQ alleles were also found: (DRB1*07)-DQA1*0201-DQB1*0303 was protective, while (DRB1*07)-DQA1*0201-DQB1*02 was neutral. The same haplotypes carried different risks for rheumatoid arthritis depending on their combination in genotypes. CONCLUSIONS When assessing the influence of HLA genes on the susceptibility to rheumatoid arthritis, not only should the HLA-DR or -DQ alleles or haplotypes be unravelled but also the genotype. The effect of HLA class II region genes is more complicated than any of the existing hypotheses can explain.

Abstract
The data from the human genome project were published in 2001. Although this achievement will boost research in the genetics of rheumatoid arthritis (RA), most of the work is in progress. Three of the four consortia that are performing linkage studies to identify loci that are transmitted more often to patients than controls have published data on genome-wide searches in few families. Of all the possible candidate genes, the human leukocyte antigen (HLA) class II region was found in the pan-European and the US linkage studies, confirming the previous data from association studies that HLA class II alleles confer risk to RA. Although HLA as a risk factor for RA has been known for a long time, the mechanism by which HLA alleles affect disease risk are controversial. Several papers have been published recently that support the RA-protection hypothesis. Several candidate loci/genes have been suggested from association studies. However, these associations have not been reproduced by different groups in several different cohorts.

Abstract
OBJECTIVE Tumor necrosis factor (TNF) is a powerful mediator of inflammation in rheumatoid arthritis (RA). In vivo, its acute effects are limited by binding to soluble receptors (TNFR), suggesting that TNFR genes could be important candidate risk factors. The present study was undertaken to investigate association of polymorphisms of TNFRI and TNFRII with RA in subjects in the UK. METHODS Unrelated Caucasian RA patients (n = 291) and healthy Caucasian controls (n = 143) were genotyped for A/G polymorphism in exon 1 of TNFRI. From this sample, 240 of the patients and 137 controls were also typed for a single-nucleotide polymorphism (SNP) in exon 6 of the TNFRII gene. In followup studies, DNA samples from UK Caucasian RA patients with a positive family history (n = 149) and UK Caucasian patients with sporadic RA (n = 208) were also typed for the exon 6 TNFRII polymorphism. RESULTS TNFRI polymorphism was not associated with RA (odds ratio [OR] for GG genotype 0.93, 95% confidence interval [95% CI] 0.54-1.60). For TNFRII, in the initial study group, patients with RA were significantly more likely to be positive for both the G allele and GG genotype than were controls (OR for GG genotype 2.55, 95% CI 1.11-5.86). The association appeared to be confined to those with a family history of RA. This finding was replicated in an independent cohort of patients with familial RA. CONCLUSION The results of this study provide evidence of association between an SNP in the TNFRII gene and RA, the strongest association being observed in patients with a family history. No evidence of association between RA and TNFRI was demonstrated.
