FCRL3 and rheumatoid arthritis: Figure 3B indicates the FCRL3 mRNA expression levels within different genotypes of rs7528684. The FCRL3 expression levels were higher in the C/C genotype (5.3 ± 0.8) than T/T genotype (1.2 ± 0.1, ***p = 0.0002) in the RA samples and in the C/C genotype of controls (3.1 ± 1.06, *p = 0.0324). These results clearly indicate higher FCRL3 gene expressions in RA patients, particularly in those carrying the C/C genotype at the FCRL3 SNP rs7528684 locus.
