Combinations of Interleukin-10 Gene Promoter Polymorphisms with -1082A, -819T, -592A Minor Allele are Associated with Sinonasal Polyposis.

Abstract

Sinonasal polyposis (SP) is an inflammatory disease involving multiple etiologies andpathogenesis. The disarray of Interleukin (IL)-10 is associated with a raised immunopathologicalresponse during the progression of many autoimmune diseases as well as theresponse to infection. We studied the possible role of the single nucleotide polymorphisms(SNPs) in IL-10 gene and their genotypic combinations in the SP pathogenesis. The IL-10’spromoter was genotyped in 200 participants (100 patients and 100 controls). The sites thatwere encompassed -1082, -819, and -592 SNP regions of extracted DNAs were analyzedby sequencing for polymorphisms. The IL-10 gene promoter polymorphisms with -1082A,-819T, -592A minor alleles, their heterozygotes and homozygotes mutant genotypes hadsignificantly higher risks for SP (P
