Apolipoprotein B Apolipoprotein B apoB is a protein that plays a role in moving cholesterol around your body.

The defect makes it hard for the body to properly digest fat and essential vitamins. Abetalipoproteinemia is caused by mutations in the MTTP gene and is inherited as an autosomal recessive genetic condition.

Multiple functions of microsomal triglyceride transfer protein. Microsomal triglyceride transfer protein and abetalipoproteinemia. Ocular clinicopathologic correlation of Hallervoden-Spatz syndrome with acanthocytosis and pigmentary retinopathy. Some current clinical trials also are posted on the following page on the NORD website: Eye exam A standard ophthalmic exam is a series of tests done to check your vision and the health of your eyes.

Lipoproteins are macromolecular complexes consisting of lipids and proteins. Call your provider if your infant or child has symptoms of this disease.

Vitamin D Vitamin D is a fat-soluble vitamin. Affected individuals may also develop degeneration of the retina of the eyes potentially resulting in loss of vision, a condition known as retinitis pigmentosa. Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted.


Some individuals may also experience irregularities in heart rhythm cardiac arrhythmias. Recent research has determined that MTP is also involved in the maturation of a family of proteins known as CD1, which are involved in lipid antigen-presentation to immune cells.

New insights into lipoprotein assembly and vitamin E metabolism from a rare genetic disease”. Mutations of the MTTP gene lead to low levels of functional MTP, which in turn, hinders the liver and intestines from making and secreting apoB-containing lipoproteins.
