Sergey Brin’s New Blog: “too” (discuss at Hacker News)

In 2004, my wife, Anne, introduced me to her future cofounders in 23andMe as they were studying the genetics of Parkinson’s Disease. As with my mother’s fear, I was skeptical about the study. I reasoned that if there was much to be learned about Parkinson’s in the genome, there would have to be a high percentage of inherited cases.

As a customer of 23andMe, I have always been excited about the product. I have found what pieces of DNA I share with various relatives. I checked whether other Brins were related.

I also looked over the health related entries and found that my genetic risk for most diseases is modestly lower than average but for a few diseases it is modestly higher.
