We describe three patients with a sensorimotor axonal polyneuropathy and an IgG M-protein that binds to a 68 kDa axonal protein identified as the low molecular weight neurofilament protein (NF-L). The immunological studies revealed that the M-proteins have different target epitopes: one is phosphorylated and the other two are nonphosphorylated. One of the nonphosphorylated epitopes is common to other intermediate filaments, such as desmin and vimentin.

Abstract
We describe three patients with a sensorimotor axonal polyneuropathy and an IgG M-protein that binds to a 68 kDa axonal protein identified as the low molecular weight neurofilament protein (NF-L). The immunological studies revealed that the M-proteins have different target epitopes: one is phosphorylated and the other two are nonphosphorylated. One of the nonphosphorylated epitopes is common to other intermediate filaments, such as desmin and vimentin.
