There was no significant difference in serum MBL level between anti-PLA2R-positive and -negative groups in patients with iMN, but in patients with aMN, serum MBL level was significantly higher in anti-PLA2R(+) groups than in anti-PLA2R(−) groups (p = .04) (Table 4). The gene discussed is MBL2; the disease is adrenomyeloneuropathy.
