Familial Thoracic Aortic Aneurysm and Dissection
Familial thoracic aortic aneurysm and dissection (TAAD) is a syndrome characterized by the formation of aneurysms or dissections in the thoracic aorta. It is often inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the genetic variant on to their offspring.
The TGFBR2 gene, located on chromosome 3, is one of the genes known to be associated with familial TAAD. Variants in this gene can lead to changes in the structure or function of the TGFBR2 protein, which plays a role in the signaling pathways that help regulate the growth and development of cells. When these signaling pathways are disrupted, it can lead to the development of aortic aneurysms and dissections.
People with familial TAAD may also have other related conditions, such as Loeys-Dietz syndrome or other inherited connective tissue disorders. Testing for changes in the TGFBR2 gene, as well as other genes known to be associated with thoracic aortic aneurysms, can help in the diagnosis and management of the condition.
Genetic testing for familial TAAD can be done using a variety of methods, including targeted gene sequencing, whole exome sequencing, or other genetic testing panels. These tests can identify changes in the TGFBR2 gene, as well as other genes known to be associated with aortic aneurysms and related conditions.
If a genetic variant is identified, it is important to consider the implications for both the affected individual and their family members. Genetic counseling and appropriate medical management should be considered for individuals with familial TAAD to help prevent complications such as aortic dissection.
