Non-HDL-C and ApoB are particularly informative in patients with hypertriglyceridemia, mixed dyslipidemia, type 2 diabetes, or metabolic syndrome, and they are also useful for identifying phenotypes such as type III hyperlipoproteinemia or high‐risk normotriglyceridemic hyperapoB individuals [11–14]. The gene discussed is APOB; the disease is hypertriglyceridemia.
