Cis-acting variants altering gene expression are a source of phenotypic differences. The cis-acting components of expression variation can be identified through the mapping of differences in allelic expression (AE), which is the measure of relative expression between two allelic transcripts. We generated a map of AE associated SNPs using quantitative measurements of AE on Illumina Human1M BeadChips. In 53 lymphoblastoid cell lines derived from donors of European descent, we identified common cis variants affecting 30% (2935/9751) of the measured RefSeq transcripts at 0.001 permutation significance. The pervasive influence of cis-regulatory variants, which explain 50% of population variation in AE, extend to full-length transcripts and their isoforms as well as to unannotated transcripts. These strong effects facilitate fine mapping of cis-regulatory SNPs, as demonstrated by dissection of heritable control of transcripts in the systemic lupus erythematosus-associated C8orf13-BLK region in chromosome 8. The dense collection of associations will facilitate large-scale isolation of cis-regulatory SNPs.

Giant cell arteritis (GCA) is a complex polygenic disease in which more than one genetic locus is likely to contribute to disease susceptibility and clinical expression. In the present study, we have analyzed for first time the implication of rs13277113 and rs2736340 variants from the C8orf13-BLK gene region in the susceptibility to GCA. A total of 220 biopsy-proven GCA patients and 486 matched controls were assessed. DNA from patients and controls was obtained from peripheral blood. Samples were genotyped for the C8orf13-BLK region rs13277113 and rs2736340 using a predesigned TaqMan allele discrimination assay. No significant differences in the genotype distribution between GCA patients and controls for the rs13277113 and rs2736340 C8orf13-BLK gene variants were found. GCA patients were also stratified according to the presence of specific clinical features of the disease. In this regard, the allele A of the rs13277113 variant was overrepresented in patients with severe ischemic manifestations compared with patients without severe ischemic manifestations (p = 0.04; OR =1.65; 95% CI = 0.99-2.78). In conclusion, our results do not support a major implication of the C8orf13-BLK gene region in susceptibility to GCA. However, a potential implication of the rs13277113 variant in the development of severe ischemic complications may exist.

In the field of genetics of SSc, we are currently reaching a period of rapid data production. Several themes are already rising from the first wave of results. First, some genetic variants clearly predispose to multiple autoimmune diseases, thus providing evidence for a shared autoimmune genetic background. Second, multiple genes are involved in the SSc predisposition and as expected the genetic associations are quite modest. Third, unless for a small number of exceptions, the causative genetic variations have not been definitively identified yet. Lastly, to date, the most convincing associations detected relate to genes playing a pivotal role in both innate and adaptative immunity. Indeed, additionally to the MHC, candidate gene studies have convincingly and reproducibly identified PTPN22, IRF5, STAT4, C8orf13-BLK, BANK1 and TNFSF4 as SSc susceptibility genes. Although these results have substantially advanced our understanding of the SSc pathogenesis, both gene-gene and gene-environment studies are now awaited in order to further improve our understanding of this multifacet disease. Finally, we should keep in mind that SSc is a very severe that is until now unfortunately free of effective therapy. Therefore, the identification of new susceptibility genes may offer a rich source of new hypotheses and experimental directions to follow that we should try to assembly in a near future to generate innovative therapies to fight this dramatic disease.

Systemic sclerosis (SSc) is a fibrotic and autoimmune disease characterized clinically by skin and internal organ fibrosis and vascular damage, and serologically by the presence of circulating autoantibodies. Although etiopathogenesis is not yet well understood, the results of numerous genetic association studies support genetic contributions as an important factor to SSc. In this paper, the major genes of SSc are reviewed. The most recent genome-wide association studies (GWAS) are taken into account along with robust candidate gene studies. The literature search was performed on genetic association studies of SSc in PubMed between January 2000 and March 2014 while eligible studies generally had over 600 total participants with replication. A few genetic association studies with related functional changes in SSc patients were also included. A total of forty seven genes or specific genetic regions were reported to be associated with SSc, although some are controversial. These genes include HLA genes, STAT4, CD247, TBX21, PTPN22, TNFSF4, IL23R, IL2RA, IL-21, SCHIP1/IL12A, CD226, BANK1, C8orf13-BLK, PLD4, TLR-2, NLRP1, ATG5, IRF5, IRF8, TNFAIP3, IRAK1, NFKB1, TNIP1, FAS, MIF, HGF, OPN, IL-6, CXCL8, CCR6, CTGF, ITGAM, CAV1, MECP2, SOX5, JAZF1, DNASEIL3, XRCC1, XRCC4, PXK, CSK, GRB10, NOTCH4, RHOB, KIAA0319, PSD3 and PSOR1C1. These genes encode proteins mainly involved in immune regulation and inflammation, and some of them function in transcription, kinase activity, DNA cleavage and repair. The discovery of various SSc-associated genes is important in understanding the genetics of SSc and potential pathogenesis that contribute to the development of this disease.
