Abstract
CD247 (or CD3‐ζ chain) is an essential adaptor and signal‐transducing molecule of the T‐cell antigen receptor (TCR) complex, and it also couples to NK‐cell activating receptors such as NKp46, NKp30 and CD16A (FcγRIII). Noncoding sequence polymorphisms and variations in CD247 expression, a tightly regulated process, have been related with an altered immune response in multiple health conditions. A single nucleotide polymorphism (T > A) at nucleotide 844 of the CD247 3′‐untranslated region, rs1052231, has been related with lower CD247 gene expression and it has been investigated as a potential biomarker of autoimmune disease. We present here a simple, accurate, reliable, time‐efficient, and cost‐effective method for CD247‐rs1052231 genotyping. Using this method, based on polymerase chain reaction with confronting two‐pair primers (PCR‐CTPP), we have also characterized the CD247‐rs1052231 genotypes in a panel of worldwide available cell lines, which should facilitate study of the role of this polymorphism in immunity and human health.

Abstract
OBJECTIVES Recent evidence has demonstrated that CD3ζ (also called CD247) play a vital role in multiple autoimmune diseases. In this study, we explored the association between CD247 gene single-nucleotide polymorphisms (SNPs) and rheumatoid arthritis (RA) in a Chinese Han population. We also evaluated the CD3ζ expression profile in peripheral blood mononuclear cells (PBMCs) from patients with RA and health controls. METHODS Three CD247 polymorphisms (rs704853, rs1214611 and rs858554) were studied in 612 patients with RA and 848 controls in a Chinese population. Genotyping was performed using the Fluidigm 192.24 Dynamic Array™ Integrated Fluidic Circuit (IFC). For gene expression study, CD3ζ mRNA levels of 36 patients with RA and 39 healthy individuals were assessed by real-time polymerase chain reaction (RT-PCR). Data were analyzed by SPSS 11.5 software. RESULTS A significant association between rs858554 polymorphism and RA was found under all genetic models (all p < 0.05). Moreover, we found the genotype distribution and allele frequency of rs858554 were significant associated with ACCP+ and RF+ phenotype as compare to health controls (all p < 0.05). Unfortunately, we did not detect any significant associations between rs704853, rs1214611 and RA susceptibility and autoantibody profiles (all p > 0.05). The gene expression assays showed that CD3ζ mRNA levels were downregulated in PBMCs of patients with RA when compared to healthy controls. CONCLUSIONS Our results, the first reported for distinct Chinese populations, support a role of the CD247 gene in the susceptibility to RA. Further studies with more sample size are necessary to clarify the exact role of CD247 gene in the pathogenesis of RA.

Genetic association of CD247 (CD3ζ) with SLE in a large-scale multiethnic study. Genes Immun 2015; 16:142-50.

Abstract
A classic T-cell phenotype in systemic lupus erythematosus (SLE) is the downregulation and replacement of the CD3ζ chain that alters T-cell receptor signaling. However, genetic associations with SLE in the human CD247 locus that encodes CD3ζ are not well established and require replication in independent cohorts. Our aim was therefore to examine, localize and validate CD247-SLE association in a large multiethnic population. We typed 44 contiguous CD247 single-nucleotide polymorphisms (SNPs) in 8922 SLE patients and 8077 controls from four ethnically distinct populations. The strongest associations were found in the Asian population (11 SNPs in intron 1, 4.99 × 10(-4) < P < 4.15 × 10(-2)), where we further identified a five-marker haplotype (rs12141731-rs2949655-rs16859085-rs12144621-rs858554; G-G-A-G-A; P(hap) = 2.12 × 10(-5)) that exceeded the most associated single SNP rs858554 (minor allele frequency in controls = 13%; P = 4.99 × 10(-4), odds ratio = 1.32) in significance. Imputation and subsequent association analysis showed evidence of association (P < 0.05) at 27 additional SNPs within intron 1. Cross-ethnic meta-analysis, assuming an additive genetic model adjusted for population proportions, showed five SNPs with significant P-values (1.40 × 10(-3) < P< 3.97 × 10(-2)), with one (rs704848) remaining significant after Bonferroni correction (P(meta) = 2.66 × 10(-2)). Our study independently confirms and extends the association of SLE with CD247, which is shared by various autoimmune disorders and supports a common T-cell-mediated mechanism.

Abstract
Given the role of CD247 in the response of the T cells, its entailment in autoimmune diseases and in order to better clarify the role of this gene in RA susceptibility, we aimed to analyze CD247 gene variants previously associated with other autoimmune diseases (rs1052237, rs2056626 and rs864537) in a large independent European Caucasian population. However, no evidence of association was found for the analyzed CD247 single-nucleotide polymorphisms (SNPs) with RA and with the presence/absence of anti-cyclic citrullinated polypeptide. We performed a meta-analysis including previously published GWAS data from the rs864537 variant, revealing an overall genome-wide significant association between this CD247 SNP and RA with anti-CCP (OR = 0.90, CI 95% = 0.87-0.93, Poverall = 2.1×10(-10)). Our results show for first time a GWAS-level association between this CD247 polymorphism and RA risk.

Abstract
Systemic sclerosis (SSc) is a multisystemic fibrotic disorder that affects the skin and internal organs. Despite an improved outcome probably reflecting a better management of disease complications, morbidity and mortality remain higher than those of patients with other connective tissue diseases. SSc is still considered incurable; however, during recent years, intensive research activities have deepened the understanding of pathogenic mechanisms and have led to the identification of cellular and molecular anti-fibrotic targets. This review article will discuss potential future targeted therapeutic options based on data from in vitro studies, experimental models of fibrosis and first human trials with focus on scleroderma skin and lung fibrosis.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease with complex genetic inheritance. CD247 (CD3Z, TCRZ) plays a vital role in antigen recognition and signal transduction in antigen-specific immune responses, and is known to be involved in SLE pathogenesis. Weak disease association was reported for genetic variants in this gene in Caucasian studies for SLE, Crohn's disease and systemic sclerosis, but its role as a genetic risk factor was never firmly established. METHODS In this study, using a collection of 612 SLE patients and 2193 controls of Chinese ethnicity living in Hong Kong in a genome-wide study, single nucleotide polymorphisms (SNPs) in and around CD247 were identified as being associated with SLE. The two most significant SNPs in this locus were selected for further replication using TaqMan genotyping assay in 3339 Asian patients from Hong Kong, Mainland China, and Thailand, as well as 4737 ethnically and geographically matched controls. RESULTS The association of CD247 with SLE in Asian populations was confirmed (rs704853: odds ratio [OR] = 0. 81, p = 2.47 × 10(-7); rs858543: OR = 1.10, p = 0.0048). Patient-only analysis suggested that rs704853 is also linked to oral ulcers, hematologic disorders and anti-double-stranded DNA (dsDNA) antibody production. CONCLUSION A significant association between variants in CD247 and SLE was demonstrated in Asian populations. Understanding the involvement of CD247 in SLE may shed new light on disease mechanisms and development of new treatment paradigms.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs that leads to profound disability and premature death. To identify new SSc susceptibility loci, we conducted the first genome-wide association study in a population of European ancestry including a total of 2,296 individuals with SSc and 5,171 controls. Analysis of 279,621 autosomal SNPs followed by replication testing in an independent case-control set of European ancestry (2,753 individuals with SSc (cases) and 4,569 controls) identified a new susceptibility locus for systemic sclerosis at CD247 (1q22-23, rs2056626, P = 2.09 x 10(-7) in the discovery samples, P = 3.39 x 10(-9) in the combined analysis). Additionally, we confirm and firmly establish the role of the MHC (P = 2.31 x 10(-18)), IRF5 (P = 1.86 x 10(-13)) and STAT4 (P = 3.37 x 10(-9)) gene regions as SSc genetic risk factors.
