Quantile-dependent expressivity of postprandial lipemia.

ABSTRACT:

Purpose

"Quantile-dependent expressivity" describes an effect of the genotype that depends upon the level of the phenotype (e.g., whether a subject's triglycerides are high or low relative to its population distribution). Prior analyses suggest that the effect of a genetic risk score (GRS) on fasting plasma triglyceride levels increases with the percentile of the triglyceride distribution. Postprandial lipemia is well suited for testing quantile-dependent expressivity because it exposes each individual's genotype to substantial increases in their plasma triglyceride concentrations. Ninety-seven published papers were identified that plotted mean triglyceride response vs. time and genotype, which were converted into quantitative data. Separately, for each published graph, standard le
