}}[[rs1992662]] is a SNP upstream of the [[PTGER4]] gene that was found in a genome-wide association study to be associated with [[Crohn's disease]].

In several European populations, the most common allele, [[rs1992662]](T), was associated with increased risk for [[Crohn's disease]]. Conversely, the odds ratio (pooled over several populations) for the minor allele, [[rs1992662]](C), was 0.76 (CI: 0.63-0.91, p=0.0013).{{PMID|17684544|OA=1
