A large pedigree was ascertained through cases of early myocardial infarction. High density lipoprotein cholesterol and apolipoproteins A-I and A-II were measured on family members. Likelihood analysis, using the polygenic/major gene mixed model, provided no evidence that major loci play a role in determining the levels of any of the three measurements. Heritability estimates, assuming polygenic inheritance, were 0.59 and 0.26 for HDL-C level and A-II level, respectively. No evidence of genetic transmission of A-I level was found.
