Clinically, vitamin E deficiency causes a sensory peripheral neuropathy, ataxia, retinitis pigmentosa, and skeletal and cardiac myopathy. Neuropathological examination in such cases reveals loss of dorsal ganglionic neurons with degeneration of their peripheral and central axons (peripheral neuropathy and posterior column degeneration respectively). Neuroaxonal swellings are seen in the gracile and cuneate nuclei. Similar changes can be produced in rats and monkeys with experimental vitamin E deprivation.
Deficiency of the lipid-soluble vitamin E occurs in cases of intestinal malabsorption such as cystic fibrosis, congenital biliary atresia, intestinal resection, and abetalipoproteinemia (Bassen-Kornzweig syndrome).
