Aortopathies are the hereditary diseases of the aortic artery which makes it susceptible to aneurysms at any level. An aneurysm is a localized arterial dilation which when untreated can culminate in catastrophic consequences such as dissection or rupture. Aortic aneurysms convey a significant mortality burden since only 5% are forewarned by symptoms. Thoracic aneurysms are more likely to be associated with a genetic background, presenting as either part of syndromic disorder or an isolated aberration. Examples of syndromatic disorders include some collagenopathies as: Marfan Syndrome, Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome. Patients with aortic aneurysm due to hereditary disorders (Ehlers-Danlos, Loeys-Dietz Syndrome and Marfan Syndrome) can also have intracranial aneurysms. This incidence can be as high as 25%
Why to perform genetic testing in cases with suspected Hereditary Aortopathies?
- To precisely diagnose the cause of the disease and identify syndromatic forms which can present with other phenotypes in the evolution of the disease, including cerebral aneurysm.
- To identify family members at risk who may require medical follow up

What to expect from the Inherited Aortopathies genetic test panel: Up to 25% of individuals with thoracic aortic disease harbor an underlying Mendelian pathogenic variant.
