Background:
Phenotypically diverse autoimmune conditions share common genetic susceptibility loci and underlying molecular pathways.
Objectives:
By systematically searching for single nucleotide polymorphisms (SNPs) associated with another autoimmune disease, rheumatoid arthritis (RA), we aimed to elucidate novel genetic markers of psoriasis.
Methods:
We investigated 18 SNPs, previously confirmed as being associated with RA, in a U.K. cohort of 623 patients with early-onset psoriasis (presenting before age 40 years), comparing them with 2662 control subjects.
Results:
Our findings confirm the association of early-onset psoriasis with REL (rs13031237, P = 0·0027). The minor allele of REL had opposing effects upon susceptibility to disease in patients with psoriasis and RA.
Conclusion:
Similar exploration of additional autoimmune loci and fine mapping of such regions may provide further insight into the genetics and molecular pathophysiology of psoriasis.
