A patient with chorea-acanthocytosis presenting with axonal neuropathy showed an elevation in IgM polyclonal antibodies to the GM1 ganglioside, which were estimated by enzyme-linked immunosorbent assay and complement- mediated liposome immune lysis assay (LILA). This is the first demonstration of such antibodies in chorea-acanthocytosis. Anti-GM1 antibodies might have directly caused the axonal neuropathy by binding to GM1 or cross-reactive antigens in the nerves.
