CD79A and glomerular disorder: As shown in Figure 1(c), serum total IgA levels were significantly elevated in children with IgAN (215 mg/dl, 86-450 mg/dl) compared with those with non-IgA glomerular diseases (156 mg/dl, 49-455 mg/dl) and those with MC, although those levels were not elevated compared to those in HCs (193 mg/dl, 91-355 mg/dl).
