Thank you all who have been so kind to reply ....I trully appreciate it!
I have been somewhat distracted from all as of late as my mom has had a second major stroke and I am her proxy and very busy advocating as she lost speech....Who new life could this tough ... I will contact mass general as they were "treating" my father

and happen to have a sample of my brothers blood for testing ....thay found no genetic links and i don't think they even know he got it .....
thank you all
and bless you with peace and happiness!
