Lipid abnormalities in hereditary neuropathy. Part I. Serum non-polar lipids.
The non-polar lipids from sera of 54 patients, with various types of hereditary motor and sensory neuropathies, and from 72 healthy subjects were evaluated. A small but highly significant decrease in the percentage of linoleate to total fatty acids in both cholesteryl ester and triglyceride fractions was found in the sera of the neuropathy patients, except in those who had dominantly inherited sensory neuropathy (HSN-I) and who had spinocerebellar degeneration with retinitis pigmentosa and other features (SpC+). A significant decrease of serum lecithin-cholesterol acyltransferase activity was also found in those patients with hereditary motor and sensory neuropathies, Type I and Type II (two types of peroneal muscular atrophy). The biochemical basis of these abnormalities is not apparent. The biochemical abnormalities reported here have been found in several neurologic disorders and hence are unlikely to be disease-specific.
