On the heritability of serum high density lipoprotein in twins
Abstract:
To estimate the relative contributions of hereditary vs. environmental factors in the variation of high density lipoprotein, we measured the concentrations of its main apoprotein components, apoprotein A-I (apo A-I) and apoprotein A-II (apo A-II), in serum samples from 65 monozygotic (MZ) and 70 dizygotic (DZ) like-sexed twin pairs. Evidence for a genetic component of variance was found for apo A-II, giving heritability (h2) estimates of .35 and .30 for males and females, respectively. No genetic contribution to the variance of apo A-I could be demonstrated. Additionally, males had lower concentrations of apo A-I, but higher of apo A-II, than females.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
