| The purpose of this analysis was to test for genetic associations with psoriasis using a large case-control sample typed on the Affymetrix Biobank Plus array. Post-QC sample size is 11,674 people (5,960 psoriasis cases and 5,714 unaffected controls), all of European Caucasian ancestry. This association analysis was conducted solely for this submission to dbGaP; the primary reference study for these data (Tsoi et al., 2017, \"Large scale meta-analysis characterizes genetic architecture for common psoriasis-associated variants.\", Nature Communications) used only a portion of the samples typed on the Affymetrix Biobank Plus array as part of a large meta-analysis of 8 Caucasian datasets for psoriasis associations. The full post-QC dataset was used in this analysis. Separate analyses are being provided for two subsets of this sample set that were consented differently (GRU and DS). Please note that while assocation and other summary statistics are being made available for the entire sample set typed on this array platform, individual-level genotype data are being submitted for only 9,694 samples 5,476 cases and 4,218 controls), because controls collected at the University of Utah and all samples collected at Linköping University in Sweden were consented in a manner that does not allow sharing of their genotypes. |
