From the White House Blog:

The Precision Medicine Initiative: Data-Driven Treatments as Unique as Your Own Body
http://www.whitehouse.gov/blog/2015/01/30/precision-medicine-initiative-data-driven-treatments-unique-your-own-body

Includes also link to the White House plan and a video about precision medicine.

The title of the blog, as well as the three examples provided, illustrate how ‘precision medicine’ involves digital technology (not just genomics):

“• The drug ivacaftor treats the underlying cause — not the symptoms — of a particular genetic variation of cystic fibrosis.
• A variety of cancer patients are now routinely undergoing molecular testing as part of their care — and their doctors are choosing treatments based on this information.
• Physicians at the University of Michigan 3D-printed a personalized tracheal splint that saved the life of a critically ill infant with a weak trachea.”
