Open Access Abstract Association of a functional promoter polymorphism mapping to the Fc receptor-like 3 FCRL3 gene has recently been reported and replicated with rheumatoid arthritis RA in Japanese populations. The aim of this study was to investigate association of the FCRL3 gene with RA in UK subjects. DNA was available from 1065 patients with RA and 2073 population controls from the UK. Four single nucleotide polymorphism SNP markers FCRL3-169 C T fclr3_3 rs7528684 f clr3_4 rs11264799 fclr3_5 rs945635 fclr3_6 rs3761959 all previously associated with RA in a Japanese population were genotyped in 761 RA samples and 484 controls. In the remaining samples only the putative disease causal polymorphism FCRL3-169 C T was tested. Genotyping was performed using either the Sequenom MassArray iPlex platform or a 5 Allelic discrimination assay Taqman ABI . Extensive linkage disequilibrium was present across the promoter SNPs genotyped r2 values . Allele frequencies did not differ between RA cases and controls either for the putative disease causal polymorphism odds
