Wegener’s Granulomatosis

Question

My grandmother recently passed away from Wegener’s in March 2008. She had went to a lung specialist for ten years or more with the diagnosis of COPD, even though she never smoked. I find that research does not know the cause and there really isn’t a genetic link. However, my grandmother’s brother died from Wegener’s a year before her. Is this a disorder that is often misdiagnosed or rather under diagnosed?
