Familial hypercholesterolemia is a genetic disorder. It is caused by a defect on chromosome 19. The defect makes the body unable to remove low density lipoprotein (LDL, or bad) cholesterol from the blood.
Full Answer
Familial hypercholesterolemia (FH) can be caused by inherited changes (mutations) in the LDLR, APOB, and PCSK9 genes, which affect how your body regulates and removes cholesterol from your blood. About 60-80% of people with FH have a mutation found in one of these three genes.
Familial hypercholesterolemia is inherited in families in an autosomal dominant manner. In autosomal dominant inherited conditions, a parent who carries an altered gene that causes the condition has a 1 in 2 (50 percent) chance to pass on that altered gene to each of his or her children.Dec 26, 2013
Clinical characteristics: Familial hypercholesterolemia (FH) is characterized by severely elevated LDL cholesterol (LDL-C) levels that lead to atherosclerotic plaque deposition in the coronary arteries and proximal aorta at an early age, leading to an increased risk for cardiovascular disease.Dec 8, 2016
Familial Hypercholesterolemia is an autosomal dominant genetic disorder, meaning that only one parent needs to have the condition for his or her children to inherit it. The abnormal gene is dominant, so even if the child receives a healthy gene from the second parent, the altered gene will override the healthy one.Nov 17, 2014
Familial hypercholesterolemia is caused by a gene alteration that's passed down from one or both parents. People who have this condition are born with it. This change prevents the body from ridding itself of the type of cholesterol that can build up in the arteries and cause heart disease.Sep 23, 2021
High cholesterol is when you have too much of a fatty substance called cholesterol in your blood. It's mainly caused by eating fatty food, not exercising enough, being overweight, smoking and drinking alcohol. It can also run in families.
FH is caused by a mutation in one of three genes: the low-density lipoprotein cholesterol receptor (LDLR), Apolipoprotein B gene (APOB), or a gain-of-function mutation in the gene for proprotein convertase subtilisin/kexin type-9 (PCSK9).Dec 6, 2017

How does FH affect families? Familial hypercholesterolemia is a defect on chromosome 19. It is inherited as an autosomal dominant trait, which means that you only need to get the abnormal gene from one parent to inherit familial hypercholesterolemia.
The proband's genotype was confirmed to be compound heterozygous FH, leading to clinical manifestations in line with the homozygous FH phenotype. The phenotype is highly associated with the genotype in this type of compound heterozygous FH.Apr 20, 2018
Familial hypercholesterolemia (FH; OMIM ID-143890) is an autosomal dominant inherited disease, the cause of which is most often a variant in the gene for the LDL receptor (LDLR), less often a variant in the gene for its ligand, apolipoprotein B 100 (APOB).Oct 7, 2020
Familial hypercholesterolemia (FH) is an inherited defect in how the body recycles LDL (bad) cholesterol. As a result, LDL levels in the blood remain very high – in severe cases, levels can reach above 190 milligrams per deciliter (mg/dL) of blood.
One in about 200 adults have the FH genetic mutation. Including children, FH affects about 1.3 million in the U.S. But only about 10% are aware they have it.
Familial hypercholesterolemia is commonly caused by mutation in the gene for the LDL cholesterol receptor, which is involved in passing LDL from the body. Mutations in other genes can also cause inherited high cholesterol. Those genes include the PCSK9 gene and the gene for Apolipoprotein B.
FH remains underdiagnosed and undertreated. But people with FH have an excellent prognosis if the condition is identified early and treated appropriately.
Familial Hypercholesterolemia, FH for short, is an inherited disorder that leads to aggressive and premature cardiovascular disease. With this series of podcasts you will learn really what FH is, how to manage it.
