Hi David, most folks say that MSA is not hereditary but it may be. My husband passed away 01-09 of MSA-C and while we were trying to get a dx his older brother was having the same symptoms. Today he is having all of the symptoms and they dx him with ataxia and low blood pressure. He is a retired fireman and his children believe he has MSA but his new wife says no that it is just ataxia. Uh, Duh… What do you all think?
