I don't have any Marfan's in my family. But we have a host of different things: all sorts of cancers, bleeding disorders, Alzheimer's, Parkinson's, one cousin had a brain tumor, and another has situs inverse. I don't think, though, that anyone had more than one big one. My grandfather had Alzheimer's and cancer, but being old it wasn't that big a shock. I have a couple of little things (joint problems, depression, asthma) but with the CF, that's expected. I don't know anyone personally with Marfan, though Mike's doctors once thought he had it.
