On this page
Abetalipoproteinemia is caused by mutations in the MTTP gene. The MTTP gene provides instructions for making a protein called microsomal triglyceride transfer protein, which is needed for creating beta-lipoproteins. These lipoproteins are necessary for the absorption of fats, cholesterol, and fat-soluble vitamins (vitamins A, D, E and K) and for the transport of these substances in the bloodstream. The lack of beta-lipoproteins due to MTTP mutations causes the nutritional and neurological problems in individuals with this condition.
