BACKGROUND
Abetalipoproteinemia is a rare disorder of fat absorption, characterized by vitamin deficiency, acanthocytosis, and neurologic symptoms including ataxia and tremor.
METHODS
A 41-year-old male with abetalipoproteinemia is presented. He underwent staged bilateral thalamic deep brain
A 16-year-old girl, one of dizygotic twins, presented in 1976 complaining of a 1-year history of a lack of coordination and an inability to run. The results of biochemical tests confirmed the diagnosis of classic abetalipoproteinemia. In addition to the recognized neurologic features of this
Acanthocytes have a distinct morphology and are not normally found in peripheral blood. They occur in association with at least three neurological syndromes. In abetalipoproteinaemia, a progressive spinocerebellar ataxia and retinopathy occurs secondary to malabsorption of vitamin E. Cases with
The abetalipoproteinemia is a recessively inherited defect in the formation of the proteins coating chylomicrons. Their absence compromises the transport of absorbed fats out of the enterocytes into the lymphatic system and the general circulation. Clinical features include steatorrhea, retarded
There has been a recent explosion in knowledge regarding the genetic basis of several autosomal recessive ataxias. This article summarizes current information regarding rare forms of recessive ataxias. Friedreich's ataxia and ataxia telangiectasia are dealt with in other articles in this issue. The
Abetalipoproteinemia is an uncommon cause of ataxia and retinitis pigmentosa (RP). Most of the neurological and ocular manifestations occur secondary to deficiency syndromes that is consequent to fat malabsorption from the small intestine. In this report, we have described the phenotype of a young
BACKGROUND
Autosomal recessive cerebellar ataxias (ARCA) are heterogeneous and complex inherited neurodegenerative diseases that may affect the cerebellum and/or the spinocerebellar tract, the posterior column of the spinal cord and the peripheral nerves. Cerebellar ataxia is frequently proeminent
Autosomal recessive cerebellar ataxias (ARCA) are a heterogeneous group of rare neurological disorders involving both central and peripheral nervous system, and in some case other systems and organs, and characterized by degeneration or abnormal development of cerebellum and spinal cord, autosomal
BACKGROUND
Autosomal recessive cerebellar ataxias (ARCA) are a heterogeneous group of rare neurological disorders involving both central and peripheral nervous system, and in some case other systems and organs. They use to have early onset before the age of 20. Based on pathogenic mechanisms five
Autosomal recessive ataxias are a heterogeneous group of rare neurodegenerative diseases characterized by early onset cerebellar ataxia associated with various neurologic, ophthalmologic and systemic signs. In comparison with autosomal dominant ataxias, the group of recessive ataxias is less
Friedreich ataxia is the most frequent recessive cerebral ataxia d should always be researched first. Ataxia with isolated vitamin E deficiency and abetalipoproteinemia have a specific treatment. Associated neurological signs such polyneuroapthy, ophtalmologic or oculomotor signs, pyramidal signs,
Autosomal recessive cerebellar ataxias belong to a broader group of disorders known as inherited ataxias. In most cases onset occurs before the age of 20. These neurological disorders are characterized by degeneration or abnormal development of the cerebellum and spinal cord. Currently, specific
