RESULTS The 550 patients comprised 317 CRS patients (208 CRSwNP, 109 CRSsNP) and 233 controls (Table 1), all self-identified as white/Caucasian and middle-aged. In summary, we have determined that heterozygous carriers of the rs1391371 T allele are at significantly increased risk for developing CRSwNP, which further supports the potential contribution of this HLA region to CRS.
