Lipoprotein Lipase (Lpl) Gene Variation And Progression Of Carotid Artery Plaque, J. David Spence, Matthew R. Ban, Robert A. Hegele

Department of Medicine Publications

Background and Purpose - Coding single nucleotide polymorphisms (cSNPs) in the lipoprotein lipase (LPL) gene have been associated with lipoprotein phenotypes and vascular disease risk. We studied the association between LPL cSNPs and a novel noninvasive measure of disease, namely, cross-sectional carotid plaque area (CPA) on B-mode ultrasound. Methods - Four hundred fifty-two patients from an atherosclerosis prevention clinic had determinations of baseline and total CPA. Traditional atherosclerosis risk factors were recorded, and the LPL D9N, N291S, and S447X cSNPs were genotyped. Multiple regression analysis was used to identify determinants of CPA. Results - Minor allele frequencies for LPL D9N, …
