RBM4 and arthropathy: Also theDYNLL2 gene (Dynein, Light Chain, LC8-Type 2), theNFATC1 gene (Nuclear factor of activated T-cells, cytoplasmic 1), and theRBM4 gene (RNA Binding Motif Protein 4) were nominally associated, with respectively higher (DYNLL2 andNFATC1) and lower (RBM4) gene expression levels correlating with advanced joint effusion grades (Supplementary Figure 2–Supplementary Figure 4).
