Here you can see if Polyarteritis Nodosa can be hereditary. Do you have any genetic components? Does any member of your family have Polyarteritis Nodosa or may be more predisposed to developing the condition?
I think anything can be hereditary . As for this not sure but I do know it's not in my family at all. It's one of those things we really need more research on to figure out how a normal healthy individual comes down with it.
