LONDON — A decade ago, the U.K. launched its 100,000 Genomes Project, a major research endeavor that involved sequencing the DNA of that many people to discover how our genes shape our health.

The findings are already influencing clinical practice: It’s becoming standard for patients in the National Health Service with those tumors — including types of brain cancers, sarcomas, and ovarian cancers — to get their tumors sequenced.
