Marfan syndrome is inherited in an autosomal dominant manner. All individuals inherit 2 copies of each gene. In autosomal dominant conditions, an individual only has to have 1 mutation in the gene to develop the condition. The mutation can be inherited from a parent, or can happen by chance for the first time in an individual.
Each child of an individual with Marfan syndrome has a 50% chance of inheriting the mutation and the disorder. Offspring who inherit the mutation will have Marfan syndrome, although they could be more or less severely affected than their parent.
