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.
