Human thymic stromal lymphopoietin receptor (TSLPR) might play an important role in the development of inflammatory and allergic responses. We previously identified eleven single nucleotide polymorphisms (SNPs) and two variation sites in the TSLPR gene and showed that all the SNPs of the TSLPR gene are associated with susceptibility to atopic asthma. The present study aimed to investigate whether the TSLPR gene SNPs are associated with susceptibility to rheumatoid arthritis (RA). We compared the genotype and the allele frequencies of the TSLPR SNPs in 457 RA patients and 570 healthy controls. The genotype and the allele frequencies of the TSLPR gene SNPs in the RA patients were not significantly different from the respective frequencies of the healthy controls. Additional analysis showed that the genotype and the allele frequencies of the TSLPR gene SNPs did not appear to be associated with RA in female RA patients. The TSLPR gene SNPs in the RA patients did not affect the production of rheumatoid factor (RF) and antisynthetic cyclic citrullinated peptide (CCP). Our results suggest that the TSLPR gene SNPs are not associated with susceptibility to RA in the Korean population.

The present study aimed to investigate whether the polymorphisms in the TSLPR gene are associated with atopic and asthmatic disease in the Korean population. We identified eleven single nucleotide polymorphisms (SNPs) and two variation sites in the TSLPR gene, including the promoter region. The genotype and allele frequencies of g.33G>C of the TSLPR gene in asthma patients were significantly different from the respective frequencies of the control group (P = 0.006 and 0.003, respectively). Our additional analysis showed that the genotype and allele frequencies of the g.33G>C and g.19646A>G of the TSLPR gene were significantly associated in the atopic asthma patients rather than in the non-atopic asthma patients (genotype frequencies; P = 0.0001 and 0.0003 respectively, allele frequencies; P = 0.0005 and 0.0001 in that order). Our results suggest that the SNPs of the TSLPR gene could be associated with the susceptibility to atopic asthma in the Korean population.
