Sergey Brin (Google's uber-billionaire founder) has discovered via 23andme that he carries some very strongly predisposing alleles for Parkinsons.
He makes this annnouncement this on his blog, and there is a NY Times article about it.
Sergey carries G2019S of LRRK2 (leucine repeat-rich kinase 2).
The exact implications of this are not entirely clear. Early studies tend to have small samples with various selection biases. Nonetheless it is clear that I have a markedly higher chance of developing Parkinson's in my lifetime than the average person. In fact, it is somewhere between 20% to 80% depending on the study and how you measure.
