Clinical signs of familial hypercholesterolemia in patients with familial defective apolipoprotein B-100 and normal low density lipoprotein receptor function.
In a previous study (Tybjaerg-Hansen et al, Atherosclerosis 1990;80:235-242), we identified nine patients heterozygous for the apolipoprotein B (apo B) arginine-to-glutamine (Arg3,500----Gln) mutation (familial defective apolipoprotein B-100 [FDB]). Six of these had been diagnosed clinically as familial hypercholesterolemic (FH) heterozygotes. We have since examined low density lipoprotein (LDL...
متن کاملFamilial defective apolipoprotein B-100 and increased low-density lipoprotein cholesterol and coronary artery calcification in the old order amish.
BACKGROUND Elevated low-density lipoprotein cholesterol (LDL-C) levels are a major cardiovascular disease risk factor. Genetic factors are an important determinant of LDL-C levels. METHODS To identify single nucleotide polymorphisms associated with LDL-C and subclinical coronary atherosclerosis, we performed a genome-wide association study of LDL-C in 841 asymptomatic Amish individuals aged 2...
متن کاملEffect of low-density lipoprotein apheresis on kinetics of apolipoprotein B in heterozygous familial hypercholesterolemia.
The acute reduction of low-density lipoprotein (LDL) cholesterol obtained by LDL-apheresis allows the role of the high level of circulating LDL on lipoprotein metabolism in heterozygous familial hypercholesterolemia (heterozygous FH) to be addressed. We studied apolipoprotein B (apoB) kinetics in five heterozygous FH patients before and the day after an apheresis treatment using endogenous labe...
متن کاملFamilial defective apolipoprotein B-100: low density lipoproteins with abnormal receptor binding.
Previous in vivo turnover studies suggested that retarded clearance of low density lipoproteins (LDL) from the plasma of some hypercholesterolemic patients is due to LDL with defective receptor binding. The present study examined this postulate directly by receptor binding experiments. The LDL from a hypercholesterolemic patient (G.R.) displayed a reduced ability to bind to the LDL receptors on...
متن کاملLow-density lipoprotein apolipoprotein B100 turnover in hypopituitary patients with GH deficiency: a stable isotope study.
BACKGROUND Epidemiological studies suggest that hypopituitary patients have an increased risk for cardiovascular mortality. The dyslipidaemia associated with this condition is often characterised by an increase in total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol (LDL-C) and may contribute to these findings. The underlying mechanisms are not fully elucidated. MATERIALS AND ...
