Influence of the polymorphism D19H on markers of cholesterol metabolism. Cholesterol absorption is calculated as the ratio of sitosterol or campesterol to cholesterol (A, B), cholesterol synthesis is calculated as the ratio of lathosterol to cholesterol (C). Values are calculated as means ± SEM. Significance between the wild type individuals and SNP carriers was analysed with Mann–Whitney U-test (nonparametric, two-tailed). P-values <0.05 were considered as statistically significant. (GG) = wild type individual; (Gc) = carrier of p.D19H; (GG) = 93 and (Gc) = 25. * P
sitosterol = 0.0080, * P
campesterol = 0.0206.
