highly significantP = 2.4×10 −14
Only one locus, IL23R , demonstrated true independence of the psoriasis SNP; the PsA-associated SNP rs12044149 remained highly significant ( P = 2.4×10 −14 ) after conditioning on the psoriasis SNP, rs9988642, and the addition of rs9988642 did not improve the model fit with LRT ( P = 0.21).
