As shown in Table 4, in LRV entrapment group, 6 patients had incidental IgA deposits, we got kidney specimens from 5 out of the 6 patients (3 from PMN, 1 from TIN, and 1 from C3 glomerulonephritis), and Gd-IgA1 deposition was observed in all of the 5 patients (Figure 1). The gene discussed is CD79A; the disease is C3 glomerulonephritis.
