    Abstract

    Lipoprotein lipase (LPL) hydrolysis the triglyceride core of circulating chylomicrons and very-low-density lipoprotein, and modulates the levels and lipid composition of low and high density lipoproteins. Worldwide, more than 20 mutations in the LPL gene have been identified in patients with familial LPL deficiency. Most of these mutations are clustered in the region encoded by exons 4, 5 and 6 which forms the proposed catalytic domain of LPL. In French Canadians who have the highest reported frequency for LPL deficiency, three common mutations in the LPL gene have been identified which account for approximately 97% of mutant genes in this group. Simple DNA-based tests for the detection of all these mutations have been developed for the screening for carriers of LPL deficiency. This will facilitate further studies of phenotypic expression in heterozygous carriers and assessment of the risk of atherosclerosis in these individuals.
