How common is heterozygous familial hypercholesterolemia?
How common is heterozygous familial hypercholesterolemia?
Those with one parent with the condition have a 50 percent chance of inheriting FH. This form is known as heterozygous FH (HeFH). If both parents have FH, their children have a greater risk of a more serious form of the disease: homozygous FH (HoFH). These children have a 25 percent chance of inheriting FH.
How common is HeFH?
The prevalence of HeFH has been estimated to be about 1:500, and 1:1 million for HoFH making it the most common monogenic disorder encountered in clinical practice.
What does heterozygous familial hypercholesterolemia indicate?
Heterozygous Familial Hypercholesterolemia (HeFH) is an inherited genetic disorder that causes dangerously high cholesterol levels, which can lead to heart disease, heart attack, or stroke at an early age if left untreated. HeFH Is Inherited (Maybe instead: “The Difference Between HeFH and HoFH)

What are the symptoms of heterozygous?
Signs and symptoms of heterozygous FH in adults include the following:
- Long-standing history of severe hypercholesterolemia dating back to childhood.
- If no previous acute coronary event, symptoms consistent with ischemic heart disease, especially in the presence of other cardiovascular risk factors (especially smoking)
How do you confirm familial hypercholesterolemia?
Familial hypercholesterolemia (FH) can be diagnosed both clinically and genetically. FH is typically diagnosed clinically with a lipid test measuring the amount of LDL cholesterol in the blood, a physical exam, and a family history of early heart disease.
How do you treat familial hypercholesterolemia?
With familial hypercholesterolemia, your doctor likely will also recommend that you take medication to help lower your LDL cholesterol levels. The specific medication or medications depend on various factors, including your risk factors, your age, your current health and possible side effects.
How do I know if I have familial hypercholesterolemia?
Having a high cholesterol level doesn’t make you feel ill.
How to diagnose familial hypercholesterolemia?
Familial hypercholesterolaemia is usually diagnosed using clinical characteristics, such as family history, and cholesterol levels; however, genetic testing may provide a definite diagnosis of FH by detecting a pathological mutation. Current guidelines highlight the importance of reducing LDL-C levels in patients with FH.
What is the cause of familial hypercholesterolemia?
About one in 250 people has familial hypercholesterolaemia (FH), an inherited condition that means their cholesterol levels are higher than normal from birth. It’s caused by an abnormal gene and, despite it putting people at high risk of early heart disease, most of them don’t even know they have it.
