What is the difference between homozygous and heterozygous familial hypercholesterolemia?

What is the difference between homozygous and heterozygous familial hypercholesterolemia?

Heterozygous FH is characterized by very high LDL cholesterol (above 190 for adults or above 160 for children) and a family history of high cholesterol, heart disease or stroke. Homozygous FH is characterized by extremely high levels of LDL cholesterol and symptoms can be seen in childhood.

What is homozygous familial hypercholesterolemia?

Homozygous familial hypercholesterolaemia (HoFH) is a rare life-threatening condition characterized by markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and accelerated, premature atherosclerotic cardiovascular disease (ACVD).

How is heterozygous familial hypercholesterolemia diagnosed?

Diagnosis of FH may be confirmed with positive pathogenic genetic testing,25 but cannot be excluded in the absence of a causative mutation. Genetic diagnosis of FH may involve testing for either known pathogenic variants in the genes for LDL‐R, ApoB, and PCSK9 or whole‐gene sequencing.

What happens if you have familial hypercholesterolemia?

People with FH have increased blood levels of low-density lipoprotein (LDL) cholesterol, sometimes called “bad cholesterol.” Having too much LDL cholesterol in your blood increases your risk for developing coronary artery disease or having a heart attack./span>

What are the treatments for familial hypercholesterolemia?

Common medication choices include:

  • Statins.
  • Bile-acid-binding resins.
  • Cholesterol absorption inhibitors.
  • Combination cholesterol absorption inhibitor and statin.
  • Injectable medications.

How do you lower familial hypercholesterolemia naturally?

Cutting back on foods rich in cholesterol and saturated fat, such as red meat and full-fat dairy products, helps lower LDL. So does eating fish, whole grains, vegetables, and vegetable oils — all good sources of unsaturated fats.

Can you be a carrier of familial hypercholesterolemia?

Familial hypercholesterolemia (LDLRAP1-related) is known as an autosomal recessive condition. For autosomal recessive conditions, if a person has a variation in one copy of their gene, they are a carrier. This means that they are healthy because they also have a working copy of the gene.

Is familial hypercholesterolemia heart disease?

Familial hypercholesterolaemia (FH for short) is an inherited condition which can lead to extremely high cholesterol levels. It’s passed down through families in the genes. Without treatment, FH can lead to heart disease at a very young age.

What does FH do to your cells?

*People with FH have a high amount of low density lipoprotein (LDL) or “bad cholesterol” due to a mutation in one of the genes that controls the way cholesterol is cleared by the body. As a result, cholesterol accumulates in the bloodstream and can ultimately build up in the walls of the arteries.

How do you lower high inherited cholesterol?

Here are some changes you can make to help reduce your risk for high cholesterol: Healthy diet: Eating a diet high in fiber-rich grains, protein, and unsaturated fats will lower harmful LDL cholesterol. Focus on eating healthy foods such as: green vegetables.
