520 3 |a To investigate the relationship between the lipoprotein lipase Ser447Ter (S447X) mutation, lipid profiles and risk of atherosclerotic disease, we studied two groups of Japanese subjects. These groups consisted of a dyslipidemic group (triglyceride (TG) >1.69 mmol/l and high-density lipoprotein-cholesterol (HDL-C) = 0.91 mmol/l; n = 106) and a control group (TG = 1.69 mmol/l and HDL-C ≥1.16 mmol/l; n = 106). All subjects in the control group were confirmed to the pattern A phenotype (normal low-density lipoprotein (LDL) pattern), and 21 individuals in this group were heterozygous for the S447X mutation, but not homozygous. In the patient group, pattern A was shown by 44 of 106 patients. The rest were of the pattern B phenotype, which is associated with an increased risk of coronary heart disease. Homozygosity was concentrated in the patient group (p < 0.05) and in those with the pattern B phenotype (p < 0.05). In contrast, heterozygosity between both groups was not statistically significant. In conclusion, heterozygous and homozygous status with respect to the LPL S447X mutation appears to have different meanings with respect to biochemical and clinical phenotypes of atherosclerosis.
