Table 2 presents a comparison of clinical characteristics between RA patients with the GG genotype versus patients with the GC or CC genotype. No statistical differences were observed between GG genotype carriers versus GC or CC carriers in the majority of the clinical variables. GC or CC carriers had higher anti-MCV titers (p = 0.04) and a trend toward higher corticosteroid doses (p = 0.09). GG genotype carriers had similar OPG levels compared with GC or CC genotype carriers (111.3 versus 99.7 pg/mL; p = 0.32). The gene discussed is TNFRSF11B; the disease is rheumatoid arthritis.
