Mast cells are key players in NIUA and are activated by thymic stromal lymphopoietin (TSLP). This cytokine functions through recognition by its receptor, composed of IL7Rα (interleukin-7 receptor alpha) and TSLPR (TSLP receptor). These genes have been previously associated with other inflammatory diseases. <b><i>Methods:</i></b> We assessed the genetic association between single nucleotide polymorphisms (SNPs) in<i> TSLP</i>, <i>IL7R</i> and <i>TSLPR </i>and NIUA in Spanish individuals, using genotyped and imputed data. A total of 369 unrelated NIUA patients and 580 NSAID-tolerant control subjects were included, and 6 SNPs in<i> TSLP</i>, 6 in <i>IL7R</i> and 3 in <i>TSLPR </i>were genotyped. Further variants were imputed using Mach and the 1,000 Genomes Project (Phase 3) data. Association testing and statistical analyses were performed with Mach2dat and R. <b><i>Results:</i></b> A total of 139 SNPs were tested for association following quality control. Two SNPs in <i>TSLP</i> (rs1816678 and rs764917) showed a nominal association (p = 0.033 and 0.024, respectively) with NIUA, although these results were not statistically significant after correcting for multiple comparisons. <b><i>Conclusions:</i></b> Although <i>TSLP, IL7R </i>and<i> TSLPR</i> are important genes involved in the development of the inflammatory response, we found no significant genetic association with NIUA in our population for common SNPs in these genes.</p>
