4. Marfan Syndrome can be Passed by a Single Parent
When it comes to passing on marfan syndrome to a child it only takes one parent to pass on this genetic disorder. A child that has a parent who has marfan syndrome faces a risk of 50 percent of also inheriting the disorder. In fact, roughly 75% of the reported total cases of Marfan syndrome are people who have only one parent that suffers from the syndrome.
The other 25 percent of people who have been diagnosed with marfan syndrome come from a spontaneous gene mutation. The reason for this gene mutation is not known. The main gene that causes marfan syndrome was first found in 1991. While marfan syndrome is not contagious and only passed on through genetics, it is possible for a gene mutation to occur at any time during a person’s life that may cause this syndrome to develop.
