A relatively rare allele at SNP rs11209026, in the IL23R gene, appears to provide a fairly strong protective effect against the development of Crohn's disease in both Jewish and non-Jewish populations. [PMID 17068223]
Note that in this study the (A;A) and (A;G) genotypes were combined for statistical reasons (there were too few (A;A) individuals to study by themselves), so the risk is shown as equal for both.
[PMID 18047540] associated With Inflammatory Bowel Diseases but Not With Celiac Disease rs11209026 had a protective effect for IBD in the case-control analysis (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.10-0.37, P= 6.6E-09). Both CD (OR 0.14, CI 0.06-0.37, P= 3.9E-07) and UC (OR 0.33, CI 0.15-0.73, P= 1.4E-03) were associated with IL23R. rs2241880 was associated with CD susceptibility (OR 1.36, CI 1.12-1.66, P= 0.0017). The population-attributable risk of carrying allele G is 0.24 and is 0.19 for homozygosity for allele G in CD.
With reference to ankylosing spondylitis, the rs11209026(A) allele also has a protective effect. The odds ratio for carriers is 0.63 (p=2.8x10e-5) based on a large study of over 1,000 Caucasian patients.[PMID 17952073, PMID 18037607]
A genome-wide association study using DNA samples from 1,052 individuals with ulcerative colitis and preexisting data from 2,571 controls, all of European ancestry, concluded that this SNP and several others were associated with altered risk for the disease.[PMID 19122664]
