I’m fascinated by genome discoveries. As someone with a genetic disease that nobody even know that it existed less than 20 years ago I always find it fascinating to learn about genetic discoveries. I was hoping this book had more cases than it actual has (love hearing about personal stories - Oliver Sacks was one of my favorite authors) but it is still pretty fascinating. There’s a bit of history, a bit of science, and a bit of stories in this book. I learned about something new and that was enough to make reading it totally worth it. I was particularly interested in learning more about Leilani Graham since our generic problem that runs in our family already has my sister using a defibrillator, just like her. It is nice to see her thrive despite all adversities - and the role that genetic advances played in helping her prolong her life and live well.
