Similarly, a higher proportion of SLC19A1 gene rs11702425 C variant was observed in RA patients (C allele: 48% in RA patients versus 32% in the control group, p < 0.001), while in GGH rs12681874, the T variant was more frequent in the normal control group (T allele: 14% in RA patients versus 26% in the control group, p = 0.002) (Figure 2). This evidence concerns the gene SLC19A1 and rheumatoid arthritis.
