Red Flags of Familial Hypercholesterolemia Red Flags of Familial Hypercholesterolemia The following are family and personal history signs that may suggest familial hypercholesterolemia (FH). They are based on guidelines from the National Institute for Health and Care Excellence (NICE) in the U.K. and the Simon Broome Diagnostic Criteria, as well as guidelines from the U.S. National Lipid Association. Y/N Red Flag Additional Information Early age of onset for coronary For men< 50 years old artery disease in self or in For women < 60 years old (Simon Broome Criteria) family (includes heart attack, For men < 55 years old stent, bypass) For women < 65 years old (National Lipid Association) For men< 50 years For women < 60 years old (Simon Broome Criteria) Family history of sudden death For men < 55 years For women < 65 years old (National Lipid Association) Total cholesterol ≥220 mg/dL Should be untreated and fasting cholesterol levels; other or LDL cholesterol ≥190 mg/dL causes of hyperlipidemia should be ruled out (NICE) in individual Tendon xanthomas Typically found on the Achilles tendon, and finger extensor (NICE, National Lipid Association) If your patient has even one “Yes”, they are suspected of having FH. Next Steps: • At least a three-generation pedigree that includes the following: o Age of onset of coronary heart disease o Lipid concentrations o Smoking history o If deceased, cause and age of death • Cholesterol screening (if it was not done previously) o Patient should be fasting and not on medication o Rule out other causes of hypercholesterolemia (i.e. diet, lack of exercise) • Referral to a cardiovascular genetics specialist for consideration of genetic testing For additional information, please see: • https://www.nice.org.uk/guidance/QS41/chapter/List-of-quality-statements • http://www.ncbi.nlm.nih.gov/books/NBK53810/ • Goldberg AC, Hopkins PN, Toth PP, et al.

    Corporate Medical Policy Genetic Testing for Familial Hypercholesterolemia AHS – M2137 File Name: genetic_testing_for_familial_hypercholesterolemia Origination: 01/01/2019 Last CAP Review: 07/2021 Next CAP Review: 07/2022 Last Review: 07/2021 Description of Procedure or Service Definitions Familial hypercholesterolemia (FH) is a genetic condition that results in premature atherosclerotic cardiovascular disease due to lifelong exposure to elevated low-density lipoprotein cholesterol (LDL-C) levels (Sturm et al., 2018). FH encompasses multiple clinical phenotypes associated with distinct molecular etiologies. The most common is an autosomal dominant disorder caused by mutations in one of three genes, low-density lipoprotein receptor (LDLR), apolipoprotein B-100 (APOB), and proprotein convertase subtilisin-like kexin type 9 (PCSK9) (Ahmad et al., 2016; Goldberg et al., 2011). Rare autosomal recessive disease results from mutation in low-density lipoprotein receptor adaptor protein (LDLRAP) (Garcia et al., 2001).

Khoury, MD, PhD h Stanford, South Pasadena, CA; Durham, NC; Montreal, Canada; Atlanta, GA; Morgantown, WV; and Philadelphia, PA Familial hypercholesterolemia (FH) is a genetic disease characterized by substantial elevations of low-density lipoprotein cholesterol, unrelated to diet or lifestyle. Untreated FH patients have 20 times the risk of developing coronary artery disease, compared with the general population. Estimates indicate that as many as 1 in 500 people of all ethnicities and 1 in 250 people of Northern European descent may have FH; nevertheless, the condition remains largely undiagnosed. In the United States alone, perhaps as little as 1% of FH patients have been diagnosed. Consequently, there are potentially millions of children and adults worldwide who are unaware that they have a life-threatening condition. In countries like the Netherlands, the United Kingdom, and Spain, cascade screening programs have led to dramatic improvements in FH case identification. Given that there are currently no systematic approaches in the United States to identify FH patients or affected relatives, the patient-centric nonprofit FH Foundation convened a national FH Summit in 2013, where participants issued a “call to action” to health care providers, professional organizations, public health programs, patient advocacy groups, and FH experts, in order to bring greater attention to this potentially deadly, but (with proper diagnosis) eminently treatable, condition.

  • Hyperlipidemia
    Hyperlipidemia Overview Hyperlipidemia (HLP) is a condition in which there are high levels of lipid (or fat) in the blood. The two main types of fat that are found in the blood are cholesterol and triglycerides. Nutrition and lifestyle factors such as maintaining a healthy weight, limiting alcohol consumption, avoiding tobacco, and adequate physical activity play a role in both the prevention and treatment of hyperlipidemia. Hyperlipidemia is the most common risk factor for the development of cardiovascular disease, which is why it is important to manage your blood lipid levels by implementing a heart healthy lifestyle. LDL Cholesterol Cholesterol is an essential component found in all human cell membranes and is required for healthy bodily functions. Your body makes all the cholesterol it needs to function and therefore the amount consumed in the diet should be limited. High levels of cholesterol in the blood increases your risk for heart disease by sticking to the walls of your arteries and causing plaque to build-up. Over time, this plaque can narrow your arteries and prevent adequate blood flow. This condition is called atherosclerosis and it is one of the primary causes of heart attack and stroke. There are two types of cholesterol, low-density lipoprotein (LDL) or “bad” cholesterol, and high-density lipoprotein (HDL) or “good” cholesterol. High levels of LDL are associated with the formation of atherosclerotic plaque. High levels of HDL have been shown to decrease the risk for heart disease and stroke by removing excess cholesterol from the bloodstream. Triglycerides Triglycerides are the most common type of fat in the body.

  • Ldl Familial Hypercholesterolemia
    WHAT IS FAMILIAL HYPERCHOLESTEROLEMIA (FH)? FH is a common condition in which the body is unable to process its natural supply of cholesterol. This inherited illness is due to one or, more rarely, two abnormal chromosomes, which make the liver ineffective at transporting cholesterol in the body. High levels of “bad” cholesterol (low-density lipoprotein-cholesterol or LDL-C) can block arteries and lead to a heart attack or stroke if left untreated.1 THINGS YOU NEED TO KNOW ABOUT FAMILIAL HYPERCHOLESTEROLEMIA WHO IS AFFECTED?

  • Familial Hypercholesterolemia
    Familial hypercholesterolemia Description Familial hypercholesterolemia is an inherited condition characterized by very high levels of cholesterol in the blood. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). The body needs this substance to build cell membranes, make certain hormones, and produce compounds that aid in fat digestion. In people with familial hypercholesterolemia, the body is unable to get rid of extra cholesterol, and it builds up in the blood. Too much cholesterol increases a person's risk of developing heart disease. People with familial hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease at a young age. This condition occurs when excess cholesterol in the bloodstream is deposited on the inner walls of blood vessels, particularly the arteries that supply blood to the heart (coronary arteries). The abnormal buildup of cholesterol forms clumps (plaques) that narrow and harden artery walls. As the plaques get bigger, they can clog the arteries and restrict the flow of blood to the heart. The buildup of plaques in coronary arteries causes a form of chest pain called angina and greatly increases a person's risk of having a heart attack. Familial hypercholesterolemia can also cause health problems related to the buildup of excess cholesterol in tissues other than the heart and blood vessels. If cholesterol accumulates in the tissues that attach muscles to bones (tendons), it causes characteristic growths called tendon xanthomas. These growths most often affect the Achilles tendons, which attach the calf muscles to the heels, and tendons in the hands and fingers.

FCHL is characterized by fluctuations in serum lipid concentrations and may present as mixed hyperlipidemia, isolated hypercholesterolemia, hypertriglyceridemia, or as a normal serum lipid profile in combination with abnormally elevated levels of apolipoprotein B. FCHL is an oligogenic primary lipid disorder, which can occur due to the interaction of several contributing variants and mutations along with environmental triggers. Controversies surround- ing the relevance of identifying FCHL as a cause of isolated hypertriglyceridemia and a differential diagnosis of familial hyper- triglyceridemia are offset by the description of associations with USF1 and other genetic traits that are unique for FCHL and that are shared with other conditions with similar pathophysiological mechanisms. Patients with FCHL are at an increased risk of cardiovascular disease and mortality and have a high frequency of comorbidity with other metabolic conditions such as type 2 diabetes, non-alcoholic fatty liver disease, steatohepatitis, and the metabolic syndrome.
