description <p>Abstract</p> <p>Background</p> <p>The chemokine receptor CCR5 has been detected at elevated levels on synovial T cells, and a 32 bp deletion in the <it>CCR5 </it>gene leads to a non-functional receptor. A negative association between the <it>CCR5Δ32 </it>and rheumatoid arthritis (RA) has been reported, although with conflicting results. In juvenile idiopathic arthritis (JIA), an association with CCR5 was recently reported. The purpose of this study was to investigate if the <it>CCR5Δ32 </it>polymorphism is associated with RA or JIA in Norwegian cohorts.</p> <p>Methods</p> <p>853 RA patients, 524 JIA patients and 658 controls were genotyped for the <it>CCR5Δ32 </it>polymorphism.</p> <p>Results</p> <p>The <it>CCR5Δ32 </it>allele frequency was 11.5% in the controls vs. 10.4% in RA patients (OR = 0.90; <it>P </it>= 0.36) and 9.7% in JIA patients (OR = 0.85; <it>P </it>= 0.20).

Combining our results with those from a recently published meta-analysis still provide evidence for a role for <it>CCR5Δ32 </it>in RA, albeit substantially weaker than the effect first reported.</p>
