Researchers Shatter the Speed Record for Diagnosing Rare Genetic Diseases with DNA Sequencing

January 12, 2022

(STAT News) – About a year ago, Matthew Kunzman’s heart was failing, despite doctors’ best attempts to bolster it with every pump and gadget they could think of. But the 14-year-old has bounced back in large part due to super-speedy genetic sequencing that pinpointed the cause of his disease and helped doctors decide how to treat it — in just 11 and a half hours. That speedy diagnosis — faster than any other medical team has previously reported — resulted from a new approach to DNA sequencing to help patients with deadly and rare diseases. On Wednesday, a team of Stanford researchers and collaborators published a letter in the New England Journal of Medicine reporting that they had sequenced 12 seriously ill patients and successfully diagnosed five of them (including Matthew). In all five cases, the information led to tangible changes in how patients were treated. (Read More)
