The heritability of adiposity [13, 14]; plasma concentrations of triglyceride [13, 15], total cholesterol [16], high-density lipoproteins [13, 17, 18], leptin [19], adiponectin [20], plasminogen activator inhibitor type-1 [21], and C-reactive protein concentrations [22]; postprandial lipemia [23]; pulmonary function [24]; and intakes of alcohol [25] and coffee [26] are quantile-dependent, whereas height and the intakes of other macronutrients are not [13, 14, 25]. The gene discussed is LEP; the disease is hyperlipidemia.
