Abetalipoproteinemia is a disease in which a person is unable to fully absorb dietary fats, cholesterol and fat-soluble vitamins. Signs and symptoms appear in the first few months of life and can include failure to gain weight and grow at the expected rate (failure to thrive); diarrhea; acanthocytosis; and stool abnormalities. Other features of this disorder may develop later in childhood and often impair the function of the nervous system, potentially causing poor muscle coordination, ataxia, and an eye disorder called retinitis pigmentosa. Abetalipoproteinemia is usually caused by mutations in the MTTP gene and is inherited in an autosomal recessive manner. Treatment may include dietary modification and various dietary supplements.

The signs and symptoms of abetalipoproteinemia appear in the first few months of life. They can include failure to gain weight and grow at the expected rate (failure to thrive); diarrhea; abnormal star-shaped red blood cells (acanthocytosis); and fatty, abnormally foul-smelling stools (steatorrhea). Other features of this disorder may develop later in childhood and often impair the function of the nervous system, causing poor muscle coordination and difficulty with balance and movement (ataxia). Individuals may also develop an eye disorder called retinitis pigmentosa, which can cause vision loss.
