Compared with SLE cases without serositis, arthritis, or hematological involvement, cases with these symptoms had much lower levels of ZFP90 mRNA expression (FDR p = 0.004, FDR p = 0.020, FDR p = 0.021, respectively, Figure 4, Table 3). This evidence concerns the gene ZFP90 and systemic lupus erythematosus.
