OT: Wilson's Disease

Anyone know anything about this? My brother said his doctor and a specialist think that he has this. I'm sure there's a bit more testing involved to verify it, but I don't know much about it. I've read a bit here and there on the internet and it seems as though I should be tested as the gene has to come from both parents and since we share the same parents... Anyway, I was just wondering if anyone has any experience with this and how it plays out? Michelle
