In further association analysis, 17 EMID2 variations (rs6945102, rs4729697, rs10237610, rs221, rs10435333, rs9640666, rs6947185, rs4729705, rs10254310, rs6949799, rs4727491, rs13238748, rs4727494, rs13233066, EMID2_BL1_ht1, EMID2_BL1_ht2, and EMID2_BL2_ht2) were initially correlated with the presence of nasal polyps in the AERD subgroup (P = 0.003-0.05, OR = 0.25-1.82 depending on the genetic model; Table 3 and Table S3). This evidence concerns the gene COL26A1 and Nasal polyposis.
