Still continuing my research into AD. I'm gathering info for a few close
friends with early diagnoses of AD, and someone younger (pushing 50) who
just found out he's an ApoE-ε4 homozygote. (And man, was I slow to
realize how radically personal genomics is going to change medicine!)
What does being ε4/ε4 mean? Well, it may mean that bexarotene would make
things WORSE. We don't know just yet, but I wouldn't take bexarotene if
I knew I were an ApoE-ε4 homozygote, because I wouldn't want elevated
levels of ApoE-ε4.
