Familial apolipoprotein A-I and C-III deficiency, variant II.

Familial apolipoprotein A-I and C-III deficiency, variant II.

The biochemical, clinical, and genetic features were examined in the proband (homozygote) and heterozygotes (n = 17) affected with familial apolipoprotein A-I and C-III deficiency, variant II (previously described as apolipoprotein A-I absence). The proband was a 45-year-old white female with mild corneal opacification and significant three-vessel coronary artery disease (CAD), who died shortly...

Studies of a variant very-low-density lipoprotein with an acquired deficiency of apolipoprotein C-II.

1. A variant very-low-density lipoprotein was associated with severe hypertriglyceridaemia. Urea-polyacrylamide gel electrophoresis of the tetramethylurea-soluble apolipoproteins of these very-low-density lipoproteins (VLDL) showed that the apolipoprotein C-II content was less than 10% of that in VLDL from hypertriglyceridaemic (3-120 mmol/l) controls. 2. VLDL were incubated with bovine milk li...

Apolipoprotein A-I/C-III/A-IV gene cluster in familial combined hyperlipidemia: effects on LDL-cholesterol and apolipoproteins B and C-III.

The underlying genetic abnormalities in familial combined hyperlipidemia (FCH) have not been elucidated, although previous association and linkage studies have implicated the apoA-I/C-III/A-IV gene cluster. We now report studies of this cluster in 18 probands, 390 family members (hyperlipidemic relatives, n = 179; normolipidemic relatives, n = 211), and 177 spouses. Three restriction enzyme pol...

Familial apolipoprotein E deficiency and type III hyperlipoproteinemia due to a premature stop codon in the apolipoprotein E gene.

A kindred with apolipoprotein E deficiency and a truncated lower molecular weight apoE mutant, designated apoE-3Washington, has been identified. Gel electrophoresis demonstrated complete absence of the normal apoE isoproteins and the presence of a small quantity of a lower molecular weight apoE. Plasma apoE levels in the proband were approximately 4% of normal. This marked deficiency of apoE re...
