RANTES ( regulated on activation, normal T-cell expressed and secreted) is a T-helper type 1 (Th1) chemokine that promotes T-cell activation and proliferation. RANTES is genetically associated with asthma, sarcoidosis and multiple sclerosis. The concentration of RANTES is increased at inflammation sites in different autoimmune diseases. Type 1 diabetes (T1D) is a Th1-mediated disease with complex genetic predisposition. We tested RANTES as a candidate gene for association with T1D using three single-nucleotide polymorphism ( SNP) variants (rs4251719, rs2306630 and rs2107538) to capture haplotype information. The minor alleles of all SNPs were transmitted less frequently to T1D offspring (transmission rates 37.3% (P = 0.002), 38.7% (P = 0.007) and 41.0% ( P = 0.01)) and were less frequently present in patients compared to controls (P = 0.009, 0.03 and 0.04, respectively). A similar protective effect was observed for the haplotype carrying three minor alleles (transmission disequilibrium test (TDT): P = 0.003; odds ratio (OR) = 0.55; confidence interval (CI): 0.37 - 0.83; case/control: P 0.03; OR 0.74; CI: 0.55 - 0.98). Both patients and controls carrying the protective haplotype express significantly lower serum levels of RANTES compared to non-carriers. Subsequently, we tested a cohort of 310 celiac disease patients, but failed to detect association. RANTES SNPs are significantly associated with RANTES serum concentration and development of T1D. The rs4251719* A-rs2306630* A-rs2107538* A haplotype associated with low RANTES production confers protection from T1D. Our data imply that RANTES is associated with T1D both genetically and functionally, and contributes to diabetes-prone Th1 cytokine profile.
