    Abstract:
    Two DNA polymorphisms adjacent to the apolipoprotein A-I/C-III and insulin genes have been suggested to be associated with hypertriglyceridemia and increased risk of coronary heart disease. Using cloned apolipoprotein A-I and insulin gene probes, we determined the genotypes of 39 subjects from six different kindreds with familial clustering of hypertriglyceridemia, 20 additional unrelated subjects with hypertriglyceridemia, 39 patients with angiographically confirmed coronary heart disease (CHD) and 61 normolipemic control subjects. The S2 allele bearing an additional SstI restriction site in the apo A-I/C-III complex was found in 16% of healthy controls, 23% of patients with CHD and 62% (P less than 0.001 when compared to controls) of unrelated subjects with hypertriglyceridemia. Among CHD patients the S2 allele was present in 6 out of 14 hypertriglyceridemic patients but only 3 out of 25 normotriglyceridemic patients (P less than 0.05). The S2 allele was present in 64% of subjects from kindreds with hypertriglyceridemia but this allele did not determine the occurrence of hyperlipidemia. The frequencies of the large size or U allele of the polymorphic DNA region flanking the 5' end of the insulin gene in CHD patients (33%) and in controls (24%) were not significantly different. Neither of the polymorphisms studied was associated with changes in serum LDL or HDL cholesterol levels in patients with CHD or unrelated subjects with hypertriglyceridemia. The data suggest that, at least in the Finnish population, the S2 allele of the apolipoprotein A-I/C-III gene complex may serve as a genetic marker for hypertriglyceridemia, whereas both DNA polymorphisms studied are probably useless in determining individual risks of atherosclerosis.
