Objective. To examine whether there is an association of eotaxin-1 gene polymorphisms with nasal polyposis (NP).
Study Design. Cross-sectional study.
Setting. Tertiary referral center.
Subjects and Methods. The study group included 85 patients with NP and 93 controls without sinonasal disease. Genotypes of eotaxin-1 (−384 A>G and +67 G>A) were identified by restriction fragment length polymorphism analyses after polymerase chain reaction.
Results. The −384 A>G and +67 G>A single nucleotide polymorphisms were higher in patients with NP than in controls (P = .044 and P = .019, respectively). However, their relation was statistically poor (association coefficient = 0.18). Consistent with this result, comparisons of allele frequencies for both single nucleotide polymorphisms were not significantly different (−384 A>G, P = .164; +67 G>A, P = .144).
Conclusion. In this study, eotaxin-1 −384 A>G or 67 G>A genotypes were not associated with susceptibility to NP.
