title: Combined effects of lipoprotein lipase and apolipoprotein E polymorphisms on lipid and lipoprotein levels in the Stanislas cohort.
abstract: We have genotyped 1101 supposedly healthy subjects from the Stanislas cohort for the lipoprotein lipase (LPL) gene Ser417(C)-->stop (G) polymorphism and/or for the apolipoprotein (apo)E common polymorphism. Genotypic effects of the two polymorphisms on fasting serum triglycerides (TG), total cholesterol (Tchol), high density lipoprotein-cholesterol (HDLc), low density lipoprotein-cholesterol (LDLc), apoB, apoA-I, and apoE levels were studied separately for each polymorphism and in conjunction. epsilon 4 allele and high apoE levels were associated with high levels of LDLc, Tchol, apoB, and TG. The G allele of LPL was significantly associated with low TG levels. We found a clear interaction between the LPL/apoE polymorphisms and apoE levels on serum TG variation. Total variability of TG levels in women and men of 42.31% and 53.62% respectively, were mainly explained by apoE concentration and these two polymorphisms. ApoE and LPL genes simultaneously modulated TG levels.
