Symptoms related to a genetic cause
Hereditary vascular diseases are a broad field of illnesses:
- Venous anomalies with an incidence estimated around 1/10,000
- Capillary malformation that affect ~0.3% of newborns
- Hereditary hemorrhagic telangiectasia with an incidence around 1/10,000
- Cerebral cavernous malformation with a prevalence of about 0.5%
Atherosclerosis is a significant cause of cardiovascular disease; it is a complex multifocal disease of arteries involving interactions of multiple genetic and environmental factors. It is characterized by endothelial dysfunction, vascular inflammation and the buildup of lipids, cholesterol, calcium, and cellular debris within the vessel wall, resulting in plaque formation and vascular insufficiency1. Atherosclerosis incorporates coronary heart disease and stroke, two of the world’s major causes of death, causing 248 deaths per 100,000 people in 2103 representing 85% of cardiovascular deaths2.
- Individuals presenting with the most common symptoms of cardiovascular disease
- Individuals with a positive family history of cardiovascular disease
- Individuals without a positive family history but with symptoms resembling the specific disease indication
- Individuals with a negative, but suspected, family history, in order to perform genetic counseling (prenatal analyses are recommended in families of affected individuals)
Confirmation of a clinical diagnosis through genetic testing allows for genetic counseling and may lead to immediate medical management. For each presented case and phenotype, a full medical report will be produced including a tailored diagnostic strategy, recommendations and a differential diagnosis, if applicable.
Clinical symptoms are not always the product of the same gene or genetic variation; any diagnosis is determined as a combination of the in-depth clinical information provided and the identified genetic cause.
What do we know about vascular diseases?
There are several vascular disorders related to genetic causalities compatible with Mendelian inheritance and multifactorial inheritance. Atherosclerosis, aortic aneurysms and hyperlipidemias are among those entities.
Genetic epidemiologic studies of atherosclerosis have identiﬁed a surprisingly long list of genetic and non-genetic risk factors for coronary artery disease. However, such studies indicate that family history is the most signiﬁcant independent risk factor; most cases of myocardial infarction (MI) and stroke result from the interactions of multiple genetic and environmental factors3. Defining genetic causes of vascular diseases such as atherosclerosis, and their role in risk stratification of coronary artery disease is the most reliable and fastest way of securing the right diagnosis, with direct implications for prevention and familial screening.
Aortic aneurysms, dissections and rupture have ranked as high as the 15th major cause of death in the United States, accounting for nearly 15,000 deaths annually4. Thoracic aortic aneurysms (TAA) tend to be asymptomatic and may not be diagnosed until a catastrophic acute aortic dissection occurs. Seven genes and two loci are known to be associated with TAAD; screening of first-order relatives of probands with TAA is essential5.
One of the most common types of hyperlipidemias occurs due to the mutations in the LDL (low density lipoprotein) receptor gene, familial hypercholesterolemia (FH). This autosomal dominant disorder affects approximately 1 in 500 individuals6. The receptor defect impairs the catabolism of LDL, and the resultant elevation in plasma LDL-cholesterol promotes deposition of cholesterol in the skin, tendons and coronary arteries (atherosclerosis)7.
