But it is also, like all agricultural stories, about mutations—"natural" mutations and man-made mutations, invisibly insidious mutations and overtly grotesque mutations, mutations that were created earlier this year at Cold Spring Harbor Laboratory and mutations that may have occurred 10,000 years ago, like the ones that transformed Solanum pimpinellifolium from a scraggly perennial weed producing pea-sized fruit along the Pacific coastal margins of Peru and Ecuador to those beautiful big-lobed heirlooms in your backyard.

Combined, IDH1 and IDH2 mutations account for about 20 percent of all AML cases.

Those studies revealed that cancer cells acquire mutations that drive them to grow aggressively.

To avoid labeling innocuous mutations as cancerous requires a bunch of statistical fine-tuning.

But many of the mutations were shared only by some of the other neurons.

Rivals such as Mirati Therapeutics Inc are also developing drugs that target KRAS mutations.

Instead of being rarities that almost inevitably harm health, mutations litter the human genome.

"About half of the 32,000 known disease-causing, single-letter mutations have one of the misspellings that ABE can fix" About half of the 32,000 known disease-causing, single-letter mutations have one of the misspellings that ABE can fix, Liu said.

Wright recently led an analysis of a commercial DNA chip and found that it was accurate only 17 percent of the time when testing for BRCA mutations and that it failed to detect actual mutations in over half of 50,000 individuals tested.

Unique cancer mutations show up in microscopic fragments of DNA in a patient's blood, which can give physicians a telltale sign of the presence of the disease in almost all types of cancer mutations — within cells or floating freely in the bloodstream.
