PRTN3 and IgA glomerulonephritis: Anti-PAR 1 (Figure 7, Figure 8, Figure 9 and Figure 10) and anti-ACE 2 (Figure 17 and Figure 18) correlated negatively with total protein and albumin levels in LN and were higher in LN than in membranous nephropathy, FSGS, IgA nephropathy, non-IgA mesangial proliferative glomerulonephritis, and c-ANCA-positive vasculitis (Figure 2 and Figure 3).
