Rs2302009

rs2302009 is a SNP located in the 3' untranslated region of the CCL26 gene. This gene (and this SNP) were discovered to be strongly associated with 117 patients with eosinophilic esophagitis, a form of esophagitis (or inflammation of the esophagus) that shares many symptoms with gastroesophageal reflux disease (GERD).

rs2302009(G) is the risk allele. The rs2302009(G;G) homozygous genotype is the most predisposed to developing eosinophilic esophagitis (odds ratio 4.55, CI 1.71&#226;&#8364;&#8220;12.39). The heterozgyote (rs2302009(G;T)) genotype's risk was indistinguishable statistically from the normal rs23020099(T;T) genotype.
