}}[[rs13431828]] is a SNP in the Interleukin-1 receptor-like 1 [[IL1RL1]] gene.

206 adult patients with surgery-unresponsive chronic [[rhinosinusitis]] and 196 matched controls were used to conclude that several SNPs in the IL1RL1 gene appeared to be protective against this condition. [[rs13431828]] showed the highest association with CRS (p = 0.008; odds ratio 0.56; CI: 0.36-0.86).{{PMID|19493384}}
