Marfan is an autosomal dominant disorder, which means that if someone inherits a defected gene from either parent, he will have Marfan syndrome. 75% of people with Marfan got it from their parents; the other 25% were the result of random mutations that happened in the first days or weeks of the pregnancy.
This syndrome is caused by a mutation in the FBN1 gene on chromosome 15, which is necessary for structural and maintenance of elastic, connective tissue fibers. Everyone has this gene in them. There are over 600 different mutations on FBN1 that can cause Marfan. FBN1 mutations can also result in other disorders as well, like ectopia lentis and MASS Phenotype.
