[An immunoelectrophoretic study of plasma lipoproteins in a case of familial deficiency of lecithin-cholesterol acyltransferase (author's transl)].

The lipid composition and apopeptide patterns of plasma LDL and VLDL have been studied in a patient with LCAT deficiency, using two-dimensional immunoelectrophoresis. After absorption of a fat meal an elevation of VLDL apopeptides C was observed. Apo-LDL also showed an abnormal relative increase of apo-C. After heparin-induced lipolysis, a shift of apo-C from chylomicra and VLDL to LDL was noticed by the striking increase of apo-C in this last lipoprotein class. In view of the present and previously published results the possible mechanisms involved in lipoprotein catabolism in LCAT deficiency are discussed.

Non-cholesterol sterols, absorption and synthesis of cholesterol and apolipoprotein A-I kinetics in a Finnish lecithin-cholesterol acyltransferase deficient family.

We describe the first Finnish LCAT-deficient family with two affected, one questionably affected and one healthy family member. The affected family members presented stomatocytes in the peripheral blood, exhibited low serum levels of total, LDL and HDL cholesterol, triglycerides, phospholipids and apolipoprotein A-I and especially A-II. Apolipoprotein A-I catabolism was accelerated to moderately high and very high levels in the two affected subjects. Cholesterol esterification percentage was low in all lipoprotein fractions. The intestinal cholesterol absorption efficiency and cholesterol and bile acid synthesis were within normal limits. The esterification percentage of demethylated cholesterol precursor sterols, cholestanol and plant sterols resembled mostly that of cholesterol, while those of VLDL and LDL methostenols, precursor sterols esterified by acyl-CoA:cholesterol acyltransferase (ACAT), suggested normal ACAT activity. In HDL all sterols were poorly esterified. The observations on stomatocytes, normal absorption and synthesis of cholesterol and bile acids, abnormal kinetics of apolipoprotein A-I, evidence of normal ACAT activity and abnormal esterification of non-cholesterol sterols are findings presented for the first time in LCAT deficiency.

Lecithin:cholesterol acyltransferase deficiency: identification of a causative gene mutation and a co-inherited protein polymorphism.

We have recreated and expressed two known natural mutations within the LCAT gene which were reported on both alleles in a single case of familial LCAT deficiency. We demonstrate that the Ala-93-->Thr mutation is responsible for the biochemical defect while the Arg-158-->Cys mutation is a co-inherited natural polymorphism of LCAT which results in normal enzyme function.
