Postmortem Aortopathy Gene Panel, Tissue
Use
This test provides a comprehensive postmortem genetic evaluation for sudden death cases attributed to thoracic aortic dissection. It is also useful for individuals with a personal or family history suggestive of Marfan syndrome, Loeys-Dietz syndrome, thoracic aortic aneurysm, and dissections or vascular Ehlers-Danlos syndrome. It identifies disease-causing variants that may assist with risk assessment and predictive testing of at-risk family members.

Limitations
NGS may not detect all genomic variants, with potential for false-negative or false-positive results. Areas high in guanine-cytosine content or with repetitive sequences may be challenging to evaluate. The test does not include deletion/duplication analysis and is not designed to detect low levels of mosaicism or differentiate between somatic and germline variants. Variants are evaluated and categorized based on their known, predicted, or possible pathogenicity.
