Abetalipoproteinemia

Abetalipoproteinemia (ABL) is a rare autosomal recessive disorder marked by low or absent levels of plasma cholesterol, low-density lipoproteins (LDLs), and very-low-density lipoproteins (VLDLs). It should not be confused with a deficiency in beta-lipoproteins. Hallmark symptoms include fat malabsorption, spinocerebellar degeneration, acanthocyte red blood cells, and retinitis pigmentosa.

Treatment aims to arrest the neuropathy and efficiency-induced complications in patients.
