Abstract
Abetalipoproteinemia (ABL) is an autosomal recessive disease caused by mutations in the microsomal triglyceride transfer protein gene. These mutations lead to fat malabsorption, with associated vitamin E deficiency, which manifests as sensory neuropathy, pigmentary retinopathy, and acanthocytosis. Treatment with vitamin E is effective in managing the neuropathy if instituted early, but the retinopathy may not be reversible or preventable. Hypo-. β-lipoproteinemia is clinically very similar to ABL but results from mutations in several unrelated genes.
