Genetic polymorphisms in chronic hyperplastic sinusitis with nasal polyposis

Abstract

TNF-alpha-308, a SNP in the promoter region of this cytokine gene is associated with increased odds of developing nasal polyposis. TNF-alpha is a potent immuno-mediator and proinflammatory cytokine that has been implicated in the pathogenesis of a large number of human diseases. The location of this gene on the short arm of chromosome 6, with the major histocompatibility complex genes and complement, has raised the probability that polymorphism within this locus may contribute to a genetic association of this region of the genome with a wide variety of infectious and autoimmune diseases.
