[Tangier disease].
Tangier disease, a familial HDL-deficiency syndrome, was first reported by Fredrickson et al. in 1961. Since then, a great deal research on the mechanism of HDL-deficiency in this disease has been done from the prospective of lipoprotein compositions, in vivo HDL kinetics, cell and receptor interactions and genomic DNA analysis. These studies have found a relatively increased fractional catabolic rate of apo HDL with essentially no change in the synthesis of apo HDL. As yet, no structural defect has been found in the apo A-I gene. However, there have been reports of irregular lipid metabolism and of disorders in the Golgi apparatus and lysosome processing. Interestingly, the frequency of coronary heart disease is low in patients with Tangier disease. In this report, we describe the clinical and biochemical characteristics of Tangier disease and suggest some possible mechanisms for preventing coronary heart disease.
