  Abetalipoproteinemia - Genetics Home Reference   (Site not responding. Last check: 2007-11-03)
Abetalipoproteinemia is an inherited disorder that affects the absorption of dietary fats, cholesterol, and certain vitamins.
A lack of beta-lipoproteins prevents absorption through the digestive tract of dietary fats and fat-soluble vitamins such as vitamins E, A, and sometimes K. Sufficient levels of fats, cholesterol, and vitamins are necessary for normal growth, development, and maintenance of the body's cells and tissues, particularly nerve cells and tissues in the eye.
Abetalipoproteinemia is a rare disorder with approximately 100 cases described worldwide.

Abetalipoproteinemia: A disorder of lipid metabolism inherited as an autosomal recessive trait characterized by the near absence of APOLIPOPROTEINS B and apoB-containing lipoproteins in plasma.
Abetalipoproteinemia is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).

Abetalipoproteinemia is an inherited metabolic defect that prevents fat-soluble vitamins, such as A and E, from being absorbed from the intestines into the bloodstream and from being secreted by the liver.

 Abetalipoproteinemia Cause, Symptoms, Treatment and Cure
Abetalipoproteinemia (ABL) is a rare inherited disorder characterized by difficulty in absorbing fat during digestion.
Treatment for abetalipoproteinemia attempts to slow down the effects of inadequate fat absorption.
Deficiency is rare, and often tied to diseases that impair the body's ability to absorb fat, such as cystic fibrosis, chronic cholestatic liver disease, short-bowel syndrome, and the rare, inherited disorder called abetalipoproteinemia.

 Bassen-Kornzweig Syndrome Information on Healthline
MTP is a gene that encodes a protein responsible for transporting triglycerides, cholesteryl esters, and components of the cell's surface called phospholipids.
Biochemical studies revealed that in biopsies from patients that lack lipoproteins (abetalipoproteinemia) and controls, MTP enzyme activity was only detected in control samples.
MTP is expressed in the lumen of the liver and intestine and is not only important for transport of lipoproteins, but also for their assembly.

Use of large amounts of vitamin E in the prevention of retrolental fibroplasia requires the supervision of a pediatrician.
Vitamin E has also been found to prevent retinopathy in people with a rare genetic disease known as abetalipoproteinemia.
People with this disorder lack a protein that transports fat-soluble nutrients, and can therefore develop deficiencies of vitamin E and other nutrients.
