clinical presentation is that of chronic axonal distal sensory neuropathy,symmetric, slowly progressive, with pain in half and much less having any weakness. The frequency in idiopathic PN is only 0.7 %, but may be as high as 25 % in certain subgroups. High titers are relatively specific for distal sensory neuropathy, whereas low titers can be seen in other conditons, including ITP, HIV, and autoimmune hepatitis. Monoclonal gammopathies occur in half.
GALOP (gait disorder, antibody, late age onset neuropathy) is a subgroup of antisulfatide neuropathy have monoclonal IgM and antibodies to sulfatide and GALOP.
