Clinical, pharmacologic, and epidemiologic evidence supports the hypothesis that common genetic pathways may underlie inflammatory diseases. In a previous study, a Crohn's disease gene, CARD15, was demonstrated to be associated with psoriatic arthritis (PsA). Recently, a functional haplotype of 2 single-nucleotide polymorphisms (SNPs) mapping to the organic cation transporter (OCTN) genes, SLC22A4 and SLC22A5, was identified as a second Crohn's disease susceptibility locus. The SLC22A4 gene has also been associated with rheumatoid arthritis. This study was undertaken to further elucidate associations of PsA with Crohn's disease susceptibility genes.
