In this study, we investigated the correlations between the FBN1 genotype-phenotype and aortic events (aortic dissection and aortic aneurysm) in patients with Marfan syndrome.
These results demonstrate that the deleterious mutations in FBN1 largely contribute to pathogenesis of sporadic non-syndromic AD, which expands our knowledge of FBN1 variants and the genetic basis and pathology of AD.
Our study provides evidence for the following: (i) FBN1 SNPs rs2118181, rs1036477, rs10519177, rs4774517, rs755251 may increase susceptibility to aortic dissections and (ii) FBN1 SNPs rs2118181, rs1036477 to the formation of aortic aneurysms.
We investigated FBN1 genotype-phenotype correlations with aortic events (aortic dissection and prophylactic aortic surgery) in patients with Marfan syndrome.
She had no systemic characteristics of Marfan syndrome, however she exhibited a mutation of FBN1, Arg 545 Cys, which has been found to correlate with ectopia lentis but not with aortic dissection.
