Fatty acid variability of plasma lipids and cholesteryl esters in adult male twins and their brothers.
Variation in the fatty acid composition of fasting plasma lipids and of cholesteryl esters was studied in 69 sets of adult male twins and 25 of their brothers. Genetic variances were estimated using the twin model. In general, monozygotic (MZ) twins were characterized by the smallest within-pair variance, and brothers of twins by the largest. Variation within dizygotic pairs fell imtermediate to that of MZ twins and brothers. The present study did not reveal consistent significant (P greater than 0.05) genetic variation in plasma fatty acids from total plasma lipids or cholesteryl esters.
