What type of mutation causes marfan syndrome? Mutations in the FBN1 gene cause Marfan syndrome. The FBN1 gene provides instructions for making a protein called fibrillin-1. Fibrillin-1 attaches (binds) to other fibrillin-1 proteins and other molecules to form threadlike filaments called microfibrils.
What kind of mutation is Marfan syndrome? Marfan syndrome is caused by defects or deletions (mutations) of the fibrillin-1 (FBN1) gene.
