Abstract

Aim: To investigate the association of single nucleotide polymorphisms (SNPs) of genes involved in the regulation of immune responses, IL33, IL1RL1, IL23R, and IL10, with idiopathic achalasia in an Italian cohort of patients. Materials and methods: A panel of eleven polymorphisms were genotyped in 116 unrelated idiopathic achalasic patients and 371 healthy subjects, by using TaqMan genotyping assays. Results: Significant differences of allele (P=0.0065, OR. = 1.59, CI. = 1.14-2.22) and genotype (P=0.0097, OR. = 1.74, CI. = 1.14-2.65) frequencies of the IL33 rs3939286 variant were found between achalasic patients and controls. No association of the other investigated SNPs was detected. No differences in genotype and allele distribution were found with respect to clinical characteristics of patients. Conclusion: We provide for the first time an association between the risk of developing idiopathic achalasia and IL-33 variant, underling the role of cytokines and inflammatory mediators on the pathogenesis of the disease.
