Rs1004819

SNP rs1004819, in the IL23R gene, is associated with increased risk for Crohn's disease in both Jewish and non-Jewish populations.

The same risk allele is also reported to increase the risk for developing ankylosing spondylitis, based on a large study of over 1,000 Caucasian patients. The odds ratio is 1.2 (p=8.8x10e-5).[PMID 17952073, PMID 18037607]
