We tested 310,605 SNPs for association in 778 individuals with celiac disease and 1,422
controls. Outside the HLA region, the most significant finding (rs13119723; P= 2.0× 10− 7)
was in the KIAA1109-TENR-IL2-IL21 linkage disequilibrium block. We independently
confirmed association in two further collections (strongest association at rs6822844, 24 kb
5′ of IL21; meta-analysis P= 1.3× 10− 14, odds ratio= 0.63), suggesting that genetic
variation in this region predisposes to celiac disease.

Abstract
We tested 310,605 SNPs for association in 778 individuals with celiac disease and 1,422 controls. Outside the HLA region, the most significant finding (rs13119723; P = 2.0 × 10−7) was in the KIAA1109-TENR-IL2-IL21 linkage disequilibrium block. We independently confirmed association in two further collections (strongest association at rs6822844, 24 kb 5′ of IL21; meta-analysis P = 1.3 × 10−14, odds ratio = 0.63), suggesting that genetic variation in this region predisposes to celiac disease.
