Since CHDL level is inversely associated with coronary heart disease in adults, it is important to quantitate C-HDL and low-density lipoprotein cholesterol (C-LDL) in hypercholesterolemic children and to identify those with putatively reduced risk (elevated C-HDL level) or increased risk (elevated C-LDL level).
The ACE/ID polymorphism seems to be a potent risk factor of coronary heart disease in subjects formerly considered to be at low risk according to common criteria.
Patterns of RFLP association were studied, to identify gene regions influencing quantitative variation in lipid and lipoprotein traits (coronary artery disease [CAD] risk factors or metabolically related traits).
Apolipoprotein B gene polymorphisms, lipoproteins and coronary atherosclerosis: a study of young myocardial infarction survivors and healthy population-based individuals.
Patients with two abnormal LDL receptor genes (homozygous deficient patients) have severe hypercholesterolemia and life-threatening coronary artery disease in childhood.
Plasma levels of two lipoprotein risk factors, high-density lipoprotein-cholesterol (HDL-C) and apolipoprotein A-1 (apo A-1), have been shown to be negatively associated with the risk of developing coronary artery disease, and several reports have examined familial factors in HDL-C and apo A-1 levels.
Studies comparing patients and controls, however, did not confirm previous studies suggesting that the multi-allelic variation at the 3'VNTR region of the apolipoprotein B gene was associated with coronary artery disease.
In a sample of both 83 healthy individuals and 105 young patients with coronary artery disease from Sweden, the frequency of the 4G allele is roughly 0.5, and those individuals homozygous for the 4G allele have higher levels of PAI-1 than those with other genotypes (29% higher).
The data suggest that variation at the LPL gene locus is associated with a pleiotropic effect, that is not directly mediated by changes in lipids, on severity of coronary atherosclerosis.
We have investigated the frequency of Hind III DNA polymorphism of the human apolipoprotein B gene in a Canadian Caucasian population with coronary artery disease, as documented by angiography, and a healthy control population.
Apolipoprotein(a) phenotypes, Lp(a) concentration and plasma lipid levels in relation to coronary heart disease in a Chinese population: evidence for the role of the apo(a) gene in coronary heart disease.
Apolipoprotein(a) phenotypes, Lp(a) concentration and plasma lipid levels in relation to coronary heart disease in a Chinese population: evidence for the role of the apo(a) gene in coronary heart disease.
We have examined DNA polymorphisms associated with the apolipoprotein B gene in 95 Sri Lankan males with ischaemic heart disease and 95 matched controls.
This result suggests the possibility that genetic variation at the LDL receptor locus or a closely linked locus on chromosome 19 may be responsible for metabolic alterations in ALP pattern B that account for a substantial proportion of the familial predisposition to coronary artery disease in the general population.
Lack of association between the apolipoprotein B gene 3' hypervariable region alleles and coronary artery disease in Finnish patients with angiographically documented coronary artery disease.
Three polymorphic sites of the apolipoprotein B gene - the insertion/deletion signal peptide, XbaI and EcoRI sites - were examined in a sample of 107 healthy men and in 46 men with evidence of coronary heart disease selected from a large population survey of South Asians aged 40-69 in London, U.K.
Lipoprotein (a) (Lp(a)) is a low density lipoprotein-like particle which contains the plasminogen-like apolipoprotein a. Lp(a) levels are elevated in patients with atherosclerotic coronary artery disease.
The value of lipoprotein (a) [Lp(a)] in the prediction of coronary artery disease risk very early in life remains to be established in different racial groups.
