Ataxia with vitamin E deficiency and severe dystonia: report of a case.
Mutation of the gene for alpha-tocopherol transfer protein causes ataxia with isolated vitamin E deficiency, a disorder usually stabilized or improved after vitamin E supplementation. Dystonia has rarely been described in ataxia with isolated vitamin E deficiency (AVED) patients. We present the case of a young boy with AVED, whose neurological and extra-neurological cardinal symptoms of the disease improved after vitamin E supplementation but who progressively developed generalized dystonia.
