Popis: Conflicting data from epidemiological trials, genetic family studies, transgenic animal models, and in vitro experiments have created controversy regarding the importance of HDL and apolipoprotein (apo) A-I for reverse cholesterol transport and protection from atherosclerosis. In this study we identified a homozygous nonsense mutation in codon 32 (Q32X) of the apoA-I gene as the molecular basis of apoA-I deficiency in a 31-year-old woman who did not present with clinical signs of atherosclerosis. Despite half-normal plasma concentrations of HDL cholesterol and apoA-I in subjects heterozygous for this mutation, the history of the patient's large family did not indicate any increased prevalence of myocardial infarction.
