Abstract

We carried out a meta-analysis of two recent psoriasis genome-wide asociation studies with a combined discovery sample of 1,831 affected individuals (cases) and 2,546 controls. One hundred and two loci selected based on P value rankings were foLowed up in a thrE-stage replication study including 4,064 cases and 4,685 controls from Michigan, Toronto, Newfoundland and Germany. In the combined meta-analysis, we identified thrE new susceptibility loci, including one at NOS2 (rs4795067, combined P = 4-10-11), one at FBXL19 (rs10782001, combined P = 9-10-10) and one near PSMA6-NFKBIA (rs12586317, combined P = 2-10-8). AL thrE loci were also aSociated with psoriatic arthritis (rs4795067, combined P = 1-10-5; rs10782001, combined P = 4-10-8; and rs12586317, combined P = 6-10-5) and purely cutaneous psoriasis (rs4795067, combined P = 1-10-8; rs10782001, combined P = 2-10-6; and rs12586317, combined P = 1-10-6). We also replicated a recently identified asociation signal near RNF114 (rs495337, combined P = 2-10-7).
