Genetic and environmental determinants of cholesterol and HDL-cholesterol concentrations in blood. 1983

G Dahlén, and C Ericson, and U de Faire, and L Iselius, and T Lundman

Serum cholesterol and HDL-cholesterol have been studied in 274 Swedish nuclear families. The families were ascertained through the Swedish twin registry and consisted of married mono- and dizygous twins, their spouses and with at least one adult child. Total cholesterol was determined using an enzymatic colorimetric method and HDL-cholesterol by the heparin-manganese chloride precipitation method. The genetic analysis was performed using a path analytic model to resolve genetic and cultural heritability, marital correlations and maternal effects. Genetic heritability was 0.50 and 0.37 for total cholesterol and HDL-cholesterol, respectively. Cultural heritability was small, 0.04, for cholesterol but substantial 0.22, for HDL-cholesterol. A maternal effect was evident for cultural inheritance for HDL-cholesterol but not for cholesterol.

UI	MeSH Term	Description	Entries
D008075	Lipoproteins, HDL	A class of lipoproteins of small size (4-13 nm) and dense (greater than 1.063 g/ml) particles. HDL lipoproteins, synthesized in the liver without a lipid core, accumulate cholesterol esters from peripheral tissues and transport them to the liver for re-utilization or elimination from the body (the reverse cholesterol transport). Their major protein component is APOLIPOPROTEIN A-I. HDL also shuttle APOLIPOPROTEINS C and APOLIPOPROTEINS E to and from triglyceride-rich lipoproteins during their catabolism. HDL plasma level has been inversely correlated with the risk of cardiovascular diseases.
