Mutation analysis of the FBN1 gene in a cohort of patients with Marfan Syndrome: A 10-year single center experience

Marfan Syndrome (MFS) is a chronic, life-threatening, autosomal dominant connective tissue disorder caused by mutations in the FBN1 gene, coding for fibrillin-1. All organ systems may be affected, but particularly the cardiovascular system, eyes, and skeleton. Mortality generally results from cardiovascular complications, mainly aortic dissection. Currently, the diagnosis of MFS is based on the revised Ghent nosology. Molecular analysis of the FBN1 gene reduces diagnostic uncertainty in patients with suspected MFS or MFS-related disorders (MFS-RD). To date, more than 2700 FBN1 mutations are known.
