A deleterious MYH11 mutation causing familial thoracic aortic dissection.


ABSTRACT: The L1264P and R1275L heterozygous mutations of the myosin heavy chain 11 (MYH11) gene, which are on the same allele, have been reported to cause thoracic aortic aneurysms and/or dissections (TAAD) complicated with patent ductus arteriosus (PDA); however, their contributions to the pathogenesis of TAAD/PDA have not been elucidated. Here we report the first familial case of TAAD with only a MYH11 L1264P mutation, in which PDA was not observed, indicating that L1264P, not R1275L, is responsible for TAAD formation.
