| Outline of Final Research Achievements |
Marfan syndrome is characterized by clinical manifestations including skeletal abnormalities, ectopia lentis, and aortic dissection / dilatation. We have been followed patients suffering from Marfan syndrome and familial aortic diseases in our facilities and tested their genetic backgrounds by candidate gene approach. Among them, we encountered one pedigree, in which three women among the six siblings suffered from aortic dissection. We detected a novel mutation: MYH11 c3766_3768 del AAG, pK1256del in this pedigree. To elucidate molecular/functional mechanism in this mutation, we established the knock-in mice which carried the aforementioned mutation by new gene editing technology Crisper-Cas 9 system. This knock-in mice have been found to mimic human phenotypes and we have continued further analyses.
