In patients with IgA nephropathy, the rate of decline of renal function over time was associated to polymorphic beta-adducin (ADD2, 1797T, rs4984) with a significant interaction with alpha-adducin (ADD1, 460W, rs4961).
Therefore, we evaluated the clinical manifestations and renal prognosis in 276 Japanese patients with histologically proven IgA</span>N with respect to their ACE I/D and ADD1 G460W polymorphisms.
