all celiac cases without these conditions and the controls, while adjusting for celiac disease status. The inclusion of the non-phenotyped dbGaP controls was not expected to have a detrimental effect on the statistical power given the rarity of the conditions. The 17 SNPs were subsequently tested using only the celiac disease cases in order to ensure that the results were not due to residual confounding with celiac disease status. Table 2 shows the association test results for the 17 SNPs that had p-values less than 0.01 in the case-control analysis. None of the 410 tested SNPs met a Bonferroni multiple test corrected p-value threshold of less than 0.00012 (0.05/410).
