Marfact #13

In honor of Marfan Syndrome awareness month, here’s today’s Marfact (provided by the wonderful Marfan Foundation).

Marfact #13: A person with Marfan syndrome has a 50% chance of passing it on to each child. It does not skip generations.

To add to this fact: There are no unaffected “carriers” of the Marfan causing gene mutation, due to the fact that it’s an Autosomal dominant disorder. This means that if a parent has the disorder you will have a 50% chance of either inheriting Marfan Syndrome from them and having the same 50% chance of passing it on to your own future child/ren or you won’t have the disorder and there will be no risk of your child getting it (at least no more risk than in the general population).

Visit for more information.


Hopefully all of the above makes sense – I’m not too great at explaining anything genetic on the best of days and right now I’m running on almost no sleep.

Hugs to you all,
Thanks for reading! ♥
