Family studies failed to demonstrate cosegregation between the new mutations and severe hyperlipoproteinemia, although a number of carriers for the APOE*3(Cys112-->Arg; Arg251-->Gly) allele and the APOE*1(Arg158-->Cys; Leu252-->Glu) allele expressed hypertriglyceridemia and/or hypercholesterolemia.
