Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy). AVED is a progressive disorder that can affect many different systems of the body (multisystem disorder). Specific symptoms vary from case to case. In addition to neurological symptoms, affected individuals may experience eye abnormalities, disorders affecting the heart muscles (cardiomyopathy), and abnormal curvature of the spine (scoliosis). AVED is extremely similar to a more common disorder known as Friedreich's ataxia. AVED is inherited as an autosomal recessive trait.
Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat metabolism, and disorders of bile secretion. These disorders include cholestasis (a syndrome of various causes characterized by impaired bile secretion); cystic fibrosis (primarily a lung disorder that may also affect bile secretion); primary biliary cirrhosis (a liver disorder that results in cholestasis); and abetalipoproteinemia (a digestive disorder characterized by fat malabsorption). Premature infants may have a low vitamin E reserve because only small amounts of vitamin E cross the placenta, and therefore they may become deficient if fed a formula high in unsaturated fats and low in vitamin E. In rare cases, vitamin E deficiency may be caused by a poor diet. (For more information on the above disorders, choose the specific disorder name your search term in the Rare Disease Database.)
