No significant associations were found between any FCRL3 SNP and CD or UC, but the stratification in patients with UC by human leukocyte antigen (HLA) showed a significant increase in heterozygosity at the FCRL3 locus, especially -169 AG (AG vs AA+GG, P= 0.0027, odds ratio = 3.6, 95% confidence interval 1.4-2.9), when HLA-DRB1*0103 carrier patients were compared with HLA-DRB1*0103 noncarriers.
