Title: Hereditary?
Post by: petgroomer on March 16, 2010, 10:21:15 pm
With schwannoma tumours, I am reading mixed reviews regarding it being hereditary.  Some places I read that the children of affected parents should be tested once they reach their late teens.  Is any part of that true?  Is it only true of certain schwannomas?  I have a vagal schwannoma.  Should I have any concerns for my 3 teen boys?  Have any of you had the same concerns or have heard the same things?
Thanks, Rhonda

My understanding is that there is no pass downs for AN's. Not sure if stats have been recorded long enough to identify this. remember, MRI's have only been around for about 25 off years. We'd really have to wait another 20 or so to get any firm analysis.

What I've read and heard is that ANs and schwannomas in general are not hereditary. That said, my eyebrows raise when I hear the rare stories on this forum of siblings with ANs. I can't remember who posted about this, unfortunately. Also can't remember if it was NF2 or just one AN per person. But at least one AN-er on this forum mentioned they also had a sibling with an AN. Maybe that was coincidence, but the odds are against coincidence with ANs. But then again, I've got two schwannomas and the one in my hypoglossal canal is 100 times more rare than an AN. What are the chance of that??!!  :o S**t happens.

Best,
