Hereditary sensory radicular neuropathy: an electrophoretic and immunoelectrophoretic study of the blood serum

摘要

The protein metabolism in four cases of hereditary sensory radicular neuropathy was studied through the electrophoresis and immunoelectrophoresis of the blood serum. A slight increase of the gammaglobulin content was found in all cases. The immunoelectrophoresis showed an absense of IgA in a case, a slight increase of IgG in all cases, and an absence of IgM in two cases and a marked decrease of this macroglobulin in two cases of the disease and in their healthy parents. Only two patients showed an increase of beta1 lipoprotein.
