A recent article in the New York Times points to a study of 53,666 sets of identical twins that looked for genetic predictors of disease. Turns out the study found little value in using genetic makeup to predict disease. An interesting finding, but not surprising, as the field is still in its infancy.
As gene sequencing becomes less expensive and more commonplace, and as sequence analysis gets faster, the data will add to our knowledge of the human body and what affects it by orders of magnitude. Genetic sequencing and analysis technology is probably at the same point now as computer technology was 50 years ago. But the rate of technological advancement is constantly speeding up. Though it took 50 years to get from room-sized computers to smart phones, it will take a fraction of that time to achieve similar advances in genetic sequencing and analysis. The benefits that will accrue to healthcare and medical device innovation are as yet unimagined.
