Subject: Is it likely my expected grandchild will inherit CMT Disease?

My son and his wife are expecting their first child.  She is 21 years old, and 
she has Charcot-Marie-Tooth Disease.  Her father also has CMTD--his onset was at 
approximately 40--45 years of age.  My son's wife, at 21, already has 
significant symptoms--drop foot, affected wrists, ankles, 'hunched back', etc.  
I realize (or I believe) there is a 50/50 chance of the baby inheriting CMT, 
however, I am wondering if the chances are greater or lesser with her being a 
daughter inheriting from her father, as opposed to if it were our son being the 
carrier?  Any information you can provide would be greatly appreciated.  I could 
not find the answer to this specifically by searching your site.  Thank you.
