Heterozygous Familial Hypercholesterolemia.

چکیده
Familial hypercholesterolemia (FH) is a genetic condition that causes high low-density lipoprotein (LDL) cholesterol (sometimes referred to as bad cholesterol) from birth. FH means high cholesterol that runs in a family. FH is caused by specific DNA changes that are passed on from parents to their children. It is not caused by lifestyle factors such as a high-fat diet or lack of exercise. There are 2 main types of FH, homozygous and heterozygous, that have different symptoms, risks, and treatments. In this Cardiology Patient Page, we focus on heterozygous FH, which we will call FH. FH affects 1 in 200 to 300 people. FH is usually inherited from 1 parent in an autosomal dominant pattern. This means a parent with FH has a 50% chance of passing it on to each child, regardless of sex. This also means all first-degree relatives (parents, siblings, and children) of a person with FH have a 50% chance to have FH, and a 50% chance to not have FH. Healthcare providers and the general public lack awareness about FH. Therefore, it is underdiagnosed and undertreated. A person with FH who is not treated is 20 times more likely to develop coronary artery disease than a person without FH. Coronary artery disease can lead to heart attacks and other major cardiovascular diseases, including stroke and sudden cardiac death. However, early diagnosis with universal lipid screening, cascade screening in families, and appropriate treatment with statins and other medications can reduce this risk.

Familial Hypercholesterolemia in Iran: A Novel Frameshift Mutation in Low Density Lipoprotein Receptor (LDLR) Gene
Background and Objective: Familial hypercholesterolemia (FH) is an autosomal trait, which is caused by mutations in Low Density Lipoprotein Receptor (LDLR) gene. FH penetrance is about 100% and worldwide prevalence for heterozygous subjects is almost 1 in 500 and for homozygous 1 in 1,000,000. The patients are at risk of premature coronary heart disease (CHD) due to defective LDLR a...

متن کاملThe influence of mevinolin on the adrenal cortical response to corticotropin in heterozygous familial hypercholesterolemia.
The biosynthesis of adrenal corticosteroids in humans depends on a continuous supply of cholesterol, which can be derived from both local synthesis and receptor-mediated uptake of low density lipoproteins (LDL) from plasma. Mevinolin, an inhibitor of 3-hydroxy-3-methylglutaryl-CoA reductase [mevalonate:NAD+ oxidoreductase (CoA-acylating), EC 1.1.1.88] is an effective hypolipidemic agent in pati...
