reported that anti-DFS70 antibodies were more common in proliferative lupus nephritis (PLN) than in membrane lupus nephritis (MLN), and the optical density O.D. value by enzyme-linked immunosorbent assay (ELISA) was associated with renal pathological activity index, highlighting the importance of investigating anti-DFS70 clinical relevance in SLE patients (15). The gene discussed is PSIP1; the disease is systemic lupus erythematosus.
