Abstract

A reduction of high density lipoprotein cholesterol (HDC) is recognized as an important risk factor for coronary artery disease (CAD). We now show in approximately 1 in 20 males with proven atherosclerosis that an Asn291Ser mutation in the human lipoprotein lipase (LPL) gene is associated with significantly reduced HDL levels (P = 0.001) and results in a significant decrease in LPL catalytic activity (P < 0.0009). The relative frequency of this mutation increases in those patients with lower HDL cholesterol levels. In vitro mutagenesis and expression studies confirm that this change is associated with a significant reduction in LPL activity. Our data support the relationship between LPL activity and HDL-C levels, and suggest that a specific LPL mutation may be a factor in the development of atherosclerosis
