MFS is caused by a mutation in FBN1, one of the genes that make fibrillin, which results in abnormal connective tissue. It is an autosomal dominant disorder. In about 75% of cases, it is inherited from a parent with the condition, while in about 25% it is a new mutation. Diagnosis is often based on the Ghent criteria, family history and genetic testing (DNA analysis).
