| الوصف: | C-C chemokine receptor 6 (CCR6) is a susceptibility gene of various immune-related diseases, which was suggested to be shared with immunoglobulin A nephropathy (IgAN). In this study, we aimed to identify the functional variants. First, we analyzed the associations ofCCR6common and rare variants detected by multi-platform chips with IgAN susceptibility using imputation and identified 68 significantly associated common variants located in the regulatory region. Among them, rs3093023 showed both statistical significance (rs3093023-A, odds ratio [OR] = 1.15,P= 2.00 × 10−2) and the expression quantitative trait loci (eQTL) effect (P= 1.45 × 10−3). It was independently replicated (rs3093023-A, OR = 1.18,P= 5.56 × 10−3) and the association was reinforced in the meta-analysis (rs3093023-A, OR = 1.17,P= 6.14 × 10−7). Although rs3093023 was in a strong linkage disequilibrium with the reportedCCR6functional variant dinucleotide polymorphism,CCR6DNP, the alleles of rs3093023 (G>A) rather than ofCCR6DNPwere shown differential nuclear protein binding effect by electrophoretic mobility shift assay. The RegulomeDB and JASPAR databases predicted Pou2f1 as the potential transcription factor, which was negatively associated withCCR6mRNA (r= −0.60,P= 3.94 × 10−9). At the mRNA level, the eQTL effect ofCCR6was validated (P= 4.39 × 10−2), andCCR6was positively associated with the expression ofCCR4andIL-17Arather than that ofCXCR3andIFNG. At the protein level, a higher CCR6+cell ratio was observed in a risk allele dose-dependent manner in lymphocytes (P= 3.57 × 10−2), CD3+T cells (P= 4.54 × 10−2), and CD4+T cells (P= 1.32 × 10−2), but not in CD8+T cells. Clinical-pathological analysis showed that rs3093023 risk allele was significantly associated with diastolic blood pressure, serum creatinine, and high ratio of tubular atrophy/interstitial fibrosis. Overall, the rs3093023 was prioritized as the function variant inCCR6, which may contribute to IgAN susceptibility by regulating Th17 cells. |
