Previously reported analyses on three different series of people suggested that fasting serum insulin levels are lower in males with (high levels of) serum Lp(a) lipoprotein (Lp(a +)) than in males without detectable Lp(a) lipoprotein (Lp(a —)). The same was observed during an oral glucose tolerance test. Also, blood glucose concentrations tended to be lower in males with high levels of Lp(a) lipoprotein than in those in whose serum no Lp(a) lipoprotein could be detected. In this paper, we present data which appear to confirm the previously reported results. A significant correlation was found between the fasting triglyceride level and the sum of insulin values determined during the oral glucose tolerance test in healthy Lp(a —) but not in Lp(a+) individuals. The present data, together with those previously reported on an effect of the Lp(a) locus on serum lipid levels and on propensity to contract coronary heart disease, indicate that the genetically determined Lp(a) lipoprotein may be of considerable clinical importance
