The mRNA expression of TGF-β1, CTGF, and VEGF-A was significantly higher in DRD when compared to proliferative nephritis (p = 0.029, p = 0.032, and p = 0.04, respectively) and to IgAN (p = 0.017, p = 0.037, and p = 0.025, respectively), but not for the podocytopathies (p>0.05 for all comparisons). The gene discussed is CCN2; the disease is dystonia 5.
