摘要: Loeys-Dietz syndrome is an autosomal dominant aortic aneurysm characterized by multisystemic involvement. The most typical clinical triad includes hypertelorism, bifid uvula or cleft palate and with tortuosity. Natural history significant for dissection at smaller diameter arterial aneurysms throughout the tree. genetic cause heterogeneous mutations in genes encoding components of transforming growth factor beta (TGFβ) signalling pathway: TGFBR1, TGFBR2, SMAD3 TGFB2. Despite loss function nature these mutations, patient-derived tissues show evidence increased (rather than decreased) TGFβ signalling. These insights offer new options therapeutic interventions.
