Indeed, 49% of apoC1 is associated with VLDL in subjects with hypertriglyceridemia [3] and 43% in subjects with combined hyperlipidemia (high level of triglycerides and LDL cholesterol), whereas the relative amounts of apoC1 in HDL decreased (respectively 51% and 57%) [3]. This evidence concerns the gene APOC1 and hypertriglyceridemia.
