Yes: Yes it is a mutation in the fbn1 gene on chromosome 15. This gene is responsible for providing the instructions for making a protien called fibrillin which becomes part of microfibrils. Microfibrils are important for providing the strength and flexibility of connective tissue.

A female with the disease and one x with the gene has a fifty fifty chance of passing it on to her children. If both of her xs have the gene, all children will get the gene. A male with the gene has a fifty fifty chance of passing it on to his daughters but cannot pass it on to his sons. ...Read more
