[英文釋義] A rare autosomal recessive familial disorder of cholesterol metabolism,characterized by extremely low HDL-cholesterol,reduced total cholesterol,and increased triglyceride levels in serum. Clinical features include the onset before age 20 years of HEPATOMEGALY; SPLENOMEGALY; the deposition of cholesterol in each TONSIL (creating a yellow-orange appearance); and RETINITIS PIGMENTOSA. A sensorimotor or distal sensory POLYNEUROPATHY occurs in approximately 50% of affected individuals. The condition is associated with decreased synthesis and increased catabolism of APOLIPOPROTEIN A-I and APOLIPOPROTEIN A-II,and a defect in cellular signaling and mobilization of lipids.
