title: Lipoprotein and hepatic lipase gene variants in coronary atherosclerosis.
abstract: Lipoprotein lipase is the rate determining enzyme for the removal of triglyceride rich lipoproteins from the blood stream. We examined whether genetic variation at the lipoprotein lipase gene locus is related to the occurrence of premature coronary artery disease. Two restriction fragment length polymorphisms, revealed by the enzymes HindIII and PvuII, demonstrated alleles designated H1 (17.5 kb), H2 (8.7 kb), P1 (7.0 kb), P2 (4.4 kb and 2.5 kb) respectively. These were studied in 70 Caucasian subjects with severe coronary atherosclerosis in comparison with 122 Caucasian healthy controls. The allelic frequencies for cases and controls were respectively: H2 0.770, 0.579 (P less than 0.001); P2 0.575, 0.554 (P NS). The allelic frequencies of the HindIII and BglII polymorphic sites at the hepatic lipase gene locus were also studied in the same groups of subjects. These showed no differences between cases and controls. We conclude that DNA variation at or adjacent to the lipoprotein lipase gene may contain genetic determinants for the occurrence of premature coronary artery disease.
