Transforming growth factor-β receptor genes (TGFBR1 and TGFBR2) are the only genes known to be associated with LDS. The aortic valve and ascending aorta are replaced simultaneously by use of a so-called composite valve graft with reimplantation of the coronary ostia into the prosthesis. Physical examination at clinical genetic evaluation showed a bifid uvula (Figure 3) but no other outward clinical signs of LDS. If an aortic aneurysm ruptures, it can cause life-threatening bleeding.
