Why the study?
Do hepatic lipase gene polymorphisms influence plasma lipid values in students with and without a paternal history of early myocardial infarction?
Do hepatic lipase gene polymorphisms influence plasma lipid values in students with and without a paternal history of early myocardial infarction?
The -C480T polymorphism in the hepatic lipase gene is associated with elevated HDL and related apolipoprotein levels, though its distribution does not differ based on paternal history of early myocardial infarction.
The -C480T allele was associated with higher HDL; hypothesis-generating for MI risk and requires prospective validation before clinical consideration.
Hepatic lipase (HL), a triglyceride lipase found in liver, adrenals, testes, and ovaries, takes part in the uptake, remodeling, and function of lipoproteins including HDL, as well as VLDL and chylomicrons. In the present study, the genotype distribution of five HL polymorphisms (-C480T, V133V, T202T, L334F, T457T) and their association to plasma lipid values were investigated. The study participants included 92 students with paternal history of myocardial infarction before the age of 55 and 194 matched control subjects, ie, the Finnish participants of the European Atherosclerosis Research Study (EARS). The allele T of the HL polymorphism -C480T showed an association with elevated HDL, apoA-I, and LpA-I values (ANOVA P < .01). No difference in genotype distribution was observed in the offspring with and without paternal history of myocardial infarction.
