Coronary heart disease risk correlates directly with plasma concentrations of lipoprotein(a) (Lp(a)), a low-density lipoprotein-like particle distinguished by the presence of the glycoprotein apolipoprotein(a) (apo(a)), which is bound to apolipoprotein B-100 (apoB-100) by disulfide bridges.
Apolipoprotein B gene polymorphisms, lipoproteins and coronary atherosclerosis: a study of young myocardial infarction survivors and healthy population-based individuals.
Apolipoprotein B levels were strongly associated with coronary artery disease in four of five prospective studies but were more predictive of coronary artery disease than were total cholesterol levels in only two of the four studies.
Another form of autosomal dominant hypercholesterolemia, familial defective apolipoprotein B-100, a genocopy of FH caused by defects in the APOB gene that lead to decreased clearance of LDL, is now established as a significant cause of coronary heart disease.
Association of the apolipoprotein B gene polymorphisms with cholesterol levels and response to fluvastatin in Brazilian individuals with high risk for coronary heart disease.
Associations of genotypes at the apolipoprotein AI-CIII-AIV, apolipoprotein B and lipoprotein lipase gene loci with coronary atherosclerosis and high density lipoprotein subclasses.
Autosomal dominant hypercholesterolemia (ADH), a major risk for coronary heart disease, is associated with mutations in the genes encoding the low-density lipoproteins receptor (LDLR), its ligand apolipoprotein B (APOB) or PCSK9 (Proprotein Convertase Subtilin Kexin 9).
Autosomal dominant hypercholesterolemia (ADH; OMIM144400), a risk factor for coronary heart disease, is characterized by an increase in low-density lipoprotein cholesterol levels that is associated with mutations in the genes LDLR (encoding low-density lipoprotein receptor) or APOB (encoding apolipoprotein B).
By direct comparison of the Lp(a) and apoB plasma concentrations in 28 affected and 31 unaffected members of seven families carrying the FH trait and without history of coronary artery disease, we reached the conclusion that LDL receptor activity is not a major determinant of the Lp(a) plasma levels in these subjects.
Cholesteryl ester transfer protein facilitates the exchange of neutral lipids between HDL and apolipoprotein B containing lipoproteins, which hold powerful opposing roles as risk factors for coronary artery disease.
