Specializes in Pediatrics

Marfans: A karyotype of someone with Marfan's Syndrome would look no different than a normal karyotype. That is because Marfan's is caused by as little as one mutation to one gene (fibrillin-1), and this mutation would not be visible in a karyotype. It is a dominant trait and if one parent is affected, it may be passed to their child.
