Genetic Causes of Monogenic Heterozygous Familial Hypercholesterolemia: A HuGE Prevalence Review

Austin, M. A.·2004·American Journal of Epidemiology

Abstract

The clinical phenotype of heterozygous familial hypercholesterolemia (FH) is characterized by increased plasma levels of total cholesterol and low density lipoprotein cholesterol, tendinous xanthomata, and premature symptoms of coronary heart disease. It is inherited as an autosomal dominant disorder with homozygotes having a more severe phenotype than do heterozygotes. FH can result from mutations in the low density lipoprotein receptor gene (LDLR), the apolipoprotein B-100 gene (APOB), and the recently identified proprotein convertase subtilisin/kexin type 9 gene (PCSK9). To date, over 700 variants have been identified in the LDLR gene. With the exception of a small number of founder populations where one or two mutations predominate, most geographically based surveys of FH subjects show a large number of mutations segregating in a given population. Studies of the prevalence of FH would be improved by the use of a consistent and uniformly applied clinical definition. Because FH responds well to drug treatment, early diagnosis to reduce atherosclerosis risk is beneficial. Cascade testing of FH family members is cost effective and merits further research. For screening to be successful, public health and general practitioners need to be aware of the signs and diagnosis of FH and the benefits of early treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
