I need the name (and any additional information, if available) of a hereditary disease or a genetic disorder that:
a) comes on later in life (post-puberty, at least)
b) is not easily detected early
c) is incurable or not easily treated
It doesn't matter if it's a physical or mental disorder, it just needs to be pretty serious.
Thanks so much!
And it looks like I'm going to go with Huntington's Disease. Thanks everyone!
