Background: Expression of matrix metalloproteinase (MMP)-9 increases in nasal polyp tissues. However, the impact of MMP-9 genotypes on the development of nasal polyposis (NP) is unknown. The aim of this study was to examine a potential association of MMP-9 promoter gene polymorphism with the development of NP. Methods: A prospective and case-control study was performed on 93 patients with NP and 115 controls without sinonasal disease. Genotypes of MMP-9 (-1562C>T) were identified by restriction fragment length polymorphism analyses after polymerase chain reaction. Results: The frequency of -1562CT genotype of MMP-9 was significantly high in NP patients with aspirin-induced asthma (p = 0.014). Distribution of T allele was significantly high in NP patients with aspirin-induced asthma (p = 0.013). MMP-9 genotypes were not associated with gender or the presence of atopy. Conclusion: In this study, MMP-9 -1562CT genotype was associated with susceptibility to NP in aspirin-induced asthmatic patients. Because this report is a population-based study, further research should be performed on larger study subjects to reveal the precise role of MMP-9 promoter gene polymorphism in the development of NP.
