Case report Novel myelin protein zero mutation (Arg36Trp) in a patient with acute onset painful neuropathy
2006
We present a patient with acute onset painful polyneuropathy found to have a novel MPZ mutation (Arg36Trp). The Arg36Trp mutation described in this report occurs at a putative adhesion interface. An alternative explanation for his polyneuropathy was not found and his mother was identified to have polyneuropathy and carry the same mutation. Two hundred normal controls were without this base alteration. The temporal profile of the index case may provide further indirect evidence suggesting an immune mechanism contributing to the pathogenesis of some cases of MPZ mutations. We predict that other rapid symptom onset polyneuropathies will be found to have direct genetic susceptibility. q 2006 Elsevier B.V. All rights reserved.
