Aortic dissection is dangerous and difficult to predict, so it is particularly important to carry out early prevention, diagnosis and rational treatment for high-risk groups. The related genes found in previous studies can not be detected in all patients with dissection; at present, the pathogenesis of non-syndromic aortic dissection is not clear, of which about 20% of patients have family aggregation and have the general representative characteristics of non-syndromic dissection. In this project, the peripheral blood samples of core family subjects were detected by sequencing technique. analyze disease-related susceptibility genes; 2 determine the effect of susceptibility genes on the incidence of dissection in mice through animal experiments; and 3 explore the effect of susceptibility genes on cell function at the cellular level.
