It is possible that the main title of the report Abetalipoproteinemia is not the name you expected.
Abetalipoproteinemia is a rare inherited disorder affecting fat metabolism. Abnormalities in fat metabolism result in malabsorption of dietary fat and various essential vitamins. Affected individuals experience progressive neurological deterioration, muscle weakness, difficulty walking, and blood abnormalities including a condition in which the red blood cells are malformed (acanthocytosis) resulting in low levels of circulating red blood cells (anemia). Affected individuals may also develop degeneration of the retina of the eyes potentially resulting in loss of vision, a condition known as retinitis pigmentosa. Abetalipoproteinemia is inherited as an autosomal recessive trait and is caused by mutations in the microsomal triglyceride transfer protein (MTTP) gene.
Abetalipoproteinemia was first reported in the medical literature by doctors Bassen and Kornzweig in 1950 and is also known as Bassen-Kornzweig syndrome. The disorder is sometimes classified as a neuroacanthocytosis syndrome, which refers to a group of disorders characterized by acanthocytosis and neurological disorders, especially movement disorders.
