Dyslipidemia is characterized by aberrant levels of circulating lipids and apolipoproteins, including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). This evidence concerns the gene APOB and metabolic syndrome.
