Anti-ganglioside peripheral nerve antibodies in Guillain-Barré syndrome (GBS) include GM1, asialo-GM1, GQ1b, GD1a, and GT1a. GM1 is associated with pure motor GBS and with the acute motor axonal variant of GBS. GM1b is also associated with GBS, but often its role in the disease is obscured by the concomitant presence of GM1. The role of GM1b in the absence of GM1 remains to be defined.
