Involvement in diseasei

Sitosterolemia (STSL) [MIM:210250]: Rare autosomal recessive disorder characterized by increased intestinal absorption of all sterols including cholesterol, plant and shellfish sterols, and decreased biliary excretion of dietary sterols into bile. Sitosterolemia patients have hypercholesterolemia, very high levels of plant sterols in the plasma, and frequently develop tendon and tuberous xanthomas, accelerated atherosclerosis and premature coronary artery disease.
Note: The disease is caused by mutations affecting the gene represented in this entry.3 Publications
