abetalipoproteinemia/asthenia

Neuroacanthocytosis is a group of rare disorders. We report a 36-year-old right-handed female who presented with gradually progressive abnormal facial movements, generalized weakness, and lower-lip biting starting 4 years ago. On examination, she had lower-lip ulcer, orofacial dyskinesias, and

Accumulation of long-chain 3-hydroxy fatty acids is the biochemical hallmark of long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) and mitochondrial trifunctional protein (MTP) deficiencies. These disorders are clinically characterized by neurological symptoms, such as convulsions and lethargy, as

We report a patient of chorea-acanthocytosis (CA), presenting with dilated cardiomyopathy and myopathy. The patient, 40-year-old male, was seen in our clinic because of progressive gait disturbance. Neurologically, he had chorea, tic, dystonia, diminished tendon reflexes and mild muscular atrophy

The clinical, electrophysiologic, and pathologic features of the peripheral neuropathy in abetalipoproteinemia (Bassen-Kornzweig disease) have been described incompletely. On the basis of findings in threee patients, we believe that large muscle fibers in peripheral nerves are selectively affected

The shapes of acanthocytic erythrocytes have been thought to be related to changes of the organization of the membrane components. In this study, acanthocytes from a patient with chorea-acanthocytosis and a patient with McLeod syndrome were examined. These acanthocytes had a greater tendency to form

We present a 70-year-old male patient of Greek origin with choreatic movements of the tongue and face, lower limb muscle weakness, peripheral neuropathy, elevated creatinephosphokinase (CPK), acanthocytosis and haemolysis in the absence of Kell RBC antigens with an additional Factor IX-deficiency.

Microsomal triglyceride transfer protein (MTP) is a dimeric protein complex consisting of protein disulfide isomerase and a unique 97 kDa subunit. In vitro, MTP accelerates the transport of triglyceride, cholesteryl ester, and phospholipid between vesicles. It was recently demonstrated that

We report two brothers who were of consanguineous parents and who displayed a unique association of motor and vocal tics, parkinsonism, distal muscular atrophy, and acanthocytosis. In the older brother, leg weakness and muscle wasting started at age 13, and he became wheelchair bound at 40.

A 27-year-old woman who had undergone extensive small bowel resection at age 14 months developed kyphoscoliosis, ocular palsies, constricted visual fields, retinitis pigmentosa, progressive ataxia, muscular weakness, nearly absent vibration and impaired position sense, areflexia, extensor plantar

We report the first case of McLeod syndrome (MLS) in a 47-year-old Chinese man who presented with progressive limb weakness, chorea of feet, red blood cell acanthocytosis, absence of Kx red blood cell antigen and weak expression of Kell antigens. The diagnosis of MLS was confirmed by genetic testing

A 52-year-old man was admitted to our hospital in 1997 because of high serum creatine kinase (CK) level. Neurologic findings revealed chorea on the trunk and extremities, mild weakness of proximal muscles, and absence of deep tendon reflexes in four extremities. Serum CK was elevated to 3,494 U/l

Vitamin E is one of the most important lipid-soluble antioxidant nutrients. Severe vitamin E deficiency can have a profound effect on the central nervous system. Cystic fibrosis, chronic cholestatic liver disease, abetalipoproteinemia, short bowel syndrome, isolated vitamin E deficiency syndrome and

Abetalipoproteinaemia (Bassen-Kornzweig syndrome), an autosomal recessive inherited disease, up to now has been described in 53 instances in the world literature. Neurological symptoms were reported in 34 of them. Ataxia, loss of proprioceptive sensation, and areflexia characterize this disorder,

A combination of unexplained peripheral neuropathy, hypoparathyroidism, and the inability to cope with metabolic stress could point to a rare inborn error of metabolism, such as mitochondrial trifunctional protein (MTP) deficiency.Here, we describe a 20-year-old woman who was known since childhood
