We did not find any association of MBL genotype groups with other clinical features, such as number of cumulative affected joints, arthritis severity index, PGA, CHAQ scores, or number of patients with uveitis, remission, or severe radiographic erosions, or with laboratory tests such as ANAs, erythrocyte sedimentation rate, and IgM-RF (Table 3). The gene discussed is MBL2; the disease is arthritic joint disease.
