As expected, IgA deposition was universally present in IgAN and IgAVN, collectively referred to as “IgA-associated renal diseases.” Elevated IgA deposition rates were also observed in several other conditions, including MIDD (80 %), LN (75 %), HBVAN (67 %), DN (51 %), and EPGN (49 %). This evidence concerns the gene CD79A and kidney disorder.
