Familial hypercholesterolemia (FH) is a common cause of cardiovascular disease and is often undiagnosed until later in life. In these populations, 1 in every 67 people has FH.7 Familial hypercholesterolemia (FH) is an autosomal dominant inherited disease - that is, you only need to inherit the defective gene from one parent to suffer from the disease - due to more than 700 mutations that affect the LDL-cholesterol receptor gene ( or bad cholesterol ). Familial hypercholesterolemia (FH) is seen in the general population at a frequency of 1 in 200 to 1 in 500. Researchers in the U.K. report that women with FH have a larger excess CVD morbidity than men . Familial hypercholesterolemia (FH) is a genetic disorder characterized by high cholesterol levels, specifically very high levels of low-density lipoprotein (LDL, "bad cholesterol"), in the blood and early cardiovascular disease.Since individuals with FH underlying body biochemistry is slightly different, their high cholesterol levels are less responsive to the kinds of cholesterol control . 11 Homozygous familial hypercholesterolemia, in which the patient possesses 2 mutated alleles, is much . and even more in certain populations, such as French-Canadian, Christian . Here are some Familial Hypercholesterolemia statistics which illustrate the gravity of this disorder: 1 in 200-500 people have FH worldwide.

Familial hypercholesterolemia (FH) is the most common autosomal dominant genetic disease. The genetic changes that cause familial hypercholesterolemia are inherited. One type of allele causes the generation of liver cells either normally or without the receptors of cholesterol. 600,000 Americans , and is more common than type 1 diabetes, cystic fibrosis and Down's Syndrome Therefore, the delineation of Abstract: Familial hypercholesterolemia (FH) is a relatively common inherited disorder caused by deleterious mutation (s) in the low-density lipoprotein (LDL) receptor or its associated genes. Familial hypercholesterolemia symptoms, linked to atherosclerosis, include: Chest pain. [2] Last updated: 1/27/2016 Familial hypercholesterolemia or FH is a condition where either one or both of your genes for the LDL receptor are defective. Worldwide, 1 in every 200-500 people has FH. 3 It can cause LDL-C levels twice as high as normal (e.g., . . 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 . Elevated levels of cholesterol can lead to a higher risk for early cardiovascular disease, and, in turn, an increased risk for heart attacks. Familial hypercholesterolemia affects the way the body processes cholesterol. Most commonly, individuals have heterozygous familial . 3, For affected individuals, the burden of illness is high. Take Note. Because signs of the condition are often only associated with unhealthy lifestyle choices, nearly 90 percent of people with FH are unaware that they have it. According to the Familial Hypercholesterolemia Foundation, individuals with FH have a 20 times higher risk of heart disease than the general population. In these populations, 1 in every 67 people has FH.7. 10 The prevalence of heterozygous familial hypercholesterolemia is about 1 in 220, based on large genetic studies. 8 Familial hypercholesterolemia is more common in certain populations due to founder effects: in certain areas of .

Classically, it was estimated that familial hypercholesterolemia affected one in 500 people worldwide, but a recent large-scale meta-analysis has shown a prevalence closer to one in 250. For example, obesity is common in familial combined and polygenic hypercholesterolemia, and weight loss may reduce LDL level. Familial hypercholesterolemia (FH) was the first of now several known monogenic disorders shown to underlie raised plasma cholesterol levels. Thus, without early detection, many patients will remain undertreated and have missed opportunities for CV prevention. Familial Hypercholesterolemia (FH) is a genetic disease which results in the reduced clearance of atherogenic LDL-cholesterol ("bad cholesterol") in the blood, and an increased risk of early heart disease. Most commonly, individuals have heterozygous familial . Certain populations are known to have a higher prevalence of FH, particularly French Canadians and Dutch Afrikaners. .

People with familial hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease at a young age. The differences observed suggest that targeted screening among subpopulations may increase the identification of cases and thus the opportunity for prevention. People with familial hypercholesterolemia need treatment much earlier than that because their LDL level starts out high even as a newborn. Thus, without early detection, many patients will remain undertreated and have missed opportunities for CV prevention. More than 600,000 people in the United .
