Abstract

The absence of normal high density lipoproteins (HDL) in Tangier disease is well established, but the properties of very low density lipoproteins (VLDL) and low density lipoproteins (LDL) in this disorder have not been well defined. The profiles obtained by analytic ultracentrifugation and the chemical composition, morphology, and electrophoretic mobility of Tangier and normal VLDL and LDL were compared. Apolipoproteins were fractionated by gel chromatography and characterized by amino acid analysis, polyacrylamide-gel electrophoresis, and immunochemical reactivity.
