title: Non-syndromic thoracic aortic aneurysms and dissections--a genetic review.
abstract: Thoracic aortic aneurysm and dissections (TAADs) are associated with both high mortality and medical expense. Poor outcomes are preventable by surgical repair; however, identifying individuals at-risk is difficult. Researchers are scanning the human genome to characterize the genetic determinants of TAADs by identifying chromosomal regions, gene mutations, single nucleotide polymorphism (SNP), genomic copy number variants and micro-RNA variants, with the purpose of analyzing the risk of TAADs associated with these predisposing genes. The goal of this review is to develop screening tests to identify individuals at risk for non-syndromic TAADs. This genetic survey has significant clinical implications because high-risk individuals can be closely monitored and can benefit from preventative surgical repair.
