In addition to these 7 CNTN1-associated MN cases reported in 2020, 14 anti-CNTN1 positive CIDP patients with MN were accumulatively described from 1987–2018 [141,142,143,144,145,146,147,148,149,150,151,152], including 10 cases with neuropathy occurring before nephropathy and 4 cases with concurrent pathologies (please see literature review by Hashimoto et al.)[152]. Here, CNTN1 is linked to chronic inflammatory demyelinating polyradiculoneuropathy.
