Research Abstract

Increased levels of plasma HDL is frequently found in~ 1% of general Japanese population. Genetic cause of high HDL levels has been uncertain except CETP deficiency. Plasma angiopoietin-like protein 3 and 4 are known as an intrinsic lipase inhibitor against lipoprotein lipase and endothelial lipase, respectively. Although every exon in these two genes was screened in subjects with increased HDL levels but without CETP deficiency, mutation was not found.
