“…An important issue when aortic dissection is found at the autopsy is the genetic screening, especially in young persons with Erdheim lesions (cystic medionecrosis) were there are no other significant associated comorbidities (atherosclerosis, trauma, etc) [7,25,26]. Usually when a genetic predisposition exists, aortic dissection is associated with various genetic syndromes (Marfan -FBN-1 or TGFbR2 mutations [27], Ehlers-Danlos IV -COL3A1 [28], Turner -45XO [29][30][31], Noonan -PTPN11, KRAS, SOS1, RAF1 [30,31], osteogenesis imperfecta -CO1A1,COL1A2 [32], homocystinuria -CBS [31], AD-PKD -PKD1, PKD2 [31], pseudoxanthoma elasticum, Hurler syndrome, Loeys-Dietz syndrome [31], etc) with manifest phenotypes. Very unfrequently aortic dissection predisposition is determined by genes that aren't responsible for other clinical manifestation.…”
