原发性胆汁性胆管炎(PBC)的全基因组关联研究(GWAS)未能发现与该病相关的X染色体(chrX)变异。在这里,我们特别探讨了chrX对PBC的贡献,PBC是一种性二态性复杂的自身免疫性疾病。我们进行了一项chrX全关联研究(XWAS),包括来自5个GWAS(来自意大利、英国、加拿大、中国、日本; 5,244例病例,11,875例对照)的基因型数据。单标记关联分析发现约100个位点显示P<5*10−4,其中最显著的是OTUD 5基因内的信号(rs3027490,P=4.80*10−6; OR=1.39 CI=1.028-1.88;日本队列)。虽然跨种族荟萃分析仅证明了提示性信号,(rs 2239452,在PIM 2基因内定位; OR=1.17,95%CI=1.09-1.26; P=9.93*10−8),人群特异性荟萃分析显示东亚人的全基因组显著位点指向同一区域(rs7059064,定位于GRIPAP 1基因内; P=6.2*10−9,OR=1.33,CI=1.21-1.46)。事实上,rs7059064标记了一个独特的LD块,包括七个基因:TIMM 17 B,PQBP 1,PIM 2,SLC 35 A2,OTUD 5,KCND 1和GRIPAP 1,以及靶向所有这些基因的超级增强子(OTUD 5内的GH 0XJ 048933)。预计GH 0XJ 048933还靶向FOXP 3,FOXP 3是主要的T调节细胞谱系特异性因子。同样,在PBC病例中OTUD 5和FOXP 3 RNA水平上调(分别为1.75和1.64倍)。这项工作代表了chrX对自身免疫性肝病遗传学贡献的第一次全面研究,并揭示了一个新的PBC相关的全基因组显著位点。原发性胆道胆管炎(PBC)是一种自身免疫性肝病,显示出强烈的女性优势。在这里,通过对X染色体进行第一次PBC遗传学研究,我们确定了一个新的基因座,其特征在于存在一个控制元件,可以调节几个PBC和自身免疫相关基因。
Genome-wide association studies (GWAS) in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually-dimorphic complex autoimmune disease. We performed a chrX-wide association study (XWAS), including genotype data from five GWAS (from Italy, UK, Canada, China, Japan; 5,244 cases, 11,875 controls). Single-marker association analyses found ~100 loci displaying P<5*10−4, with the most significant being a signal within the OTUD5 gene (rs3027490, P=4.80*10−6; OR=1.39 CI=1.028–1.88; Japanese cohort). While the transethnic meta-analysis evidenced only a suggestive signal (rs2239452, mapping within the PIM2 gene; OR=1.17, 95%CI=1.09–1.26; P=9.93*10−8), the population-specific meta-analysis showed a genome-wide significant locus in East Asians pointing to the same region (rs7059064, mapping within the GRIPAP1 gene; P=6.2*10−9, OR=1.33, CI=1.21–1.46). Indeed, rs7059064 tags a unique LD block including seven genes: TIMM17B, PQBP1, PIM2, SLC35A2, OTUD5, KCND1, and GRIPAP1, as well as a super-enhancer (GH0XJ048933 within OTUD5) targeting all these genes. GH0XJ048933 is predicted to target also FOXP3, the main T regulatory cell lineage-specification factor. Consistently, OTUD5 and FOXP3 RNA levels were upregulated in PBC cases (1.75- and 1.64-fold, respectively). This work represents the first comprehensive study of the chrX contribution to the genetics of an autoimmune liver disease and revealed a novel PBC-related genome-wide significant locus. Primary biliary cholangitis (PBC) is an autoimmune liver disease showing a strong female preponderance. Here, by performing the first PBC genetic study focused on chromosome X, we identified a novel locus characterized by the presence of a control element that may regulate several PBC and autoimmune-relevant genes.
