Abetalipoproteinemia; Acanthocytosis; Apolipoprotein B deficiency
Bassen-Kornzweig syndrome is a rare disease passed down through families. The person is unable to fully absorb dietary fats through the intestines.
I Would Like to Learn About:
Bassen-Kornzweig syndrome is caused by a defect in a gene that tells the body to create lipoproteins (molecules of fat combined with protein). The defect makes it hard for the body to properly digest fat and essential vitamins.
Balance and coordination difficulties
Curvature of spine
Decreased vision that gets worse over time
Failure to thrive (grow) in infancy
Poor muscle coordination that usually develops after age 10
Stool abnormalities, including fatty stools that appear pale in color, frothy stools, and abnormally foul-smelling stools
Loss of function of peripheral nerves, uncoordinated movement (ataxia)
When to Contact a Medical Professional
Call your provider if your infant or child has symptoms of this disease. Genetic counseling can help families understand the condition and the risks of inheriting it, and learn how to care for the person.
High doses of fat-soluble vitamins may slow the progression of some problems, such as retina damage and decreased vision.
