how can an x-linked disease be related to the age of the father????
Since sperm can carry these mutations, perhaps these could produce a spontaneous female carrier of an x-linked disorder?
Yes, definetly, the mother who has had an older father can carry the X-chromosome damage to some of her offspring. That is why with so many men fathering later there have been warnngs of double recessive conditons expanding and certainly more boys with hemophilia and Duchennes etc. Maybe some autism can be explained this way.
