Heritability of “sinking” pre‐beta lipoprotein level: a twin study

Abstract

In a twin series at the Toronto Twin Register, University of Toronto, the “sinking” pre‐beta lipoprotein fraction (sp β), quantitatively determined, was found to have a heritability index of 0.98. If confirmed, this warrants use of spβ concentration as a genetic marker. Its importance may lie in its association with angina of effort and myocardial infarction.
