The new genome-sequencing machine from Ion Torrent, a division of Life Technologies Corp., in Guilford, Connecticut, is 1,000 times more powerful than existing technology, says CEO and chairman Jonathan Rothberg.

Taking up about as much space as an office printer, it can sequence an entire genome in a single day rather than six to eight weeks required only a few years ago. The new sequencer, says cardiologist Eric Topol, chief academic officer of private California hospital and doctor network Scripps Health, "represents an exceptional advance and can change medicine."

Ion Torrent will sell the tabletop machine, called the Ion Proton Sequencer, for $99,000 to $149,000, making it affordable for large medical practices or clinics; existing sequencers cost up to $750,000. The computer chip and biochemicals to sequence a genome will cost $1,000, compared to, for example, $3,000 to test for mutations just in the BRCA genes that raise the risk of breast and ovarian cancer and $5,000 for a complete genome sequencing by Ion Torrent competitor Illumina Inc.

For now, Rothberg expects research labs to be his main customers, using Proton to obtain the complete genome sequence of people with cancer or autism, for instance, and thereby elucidate a disease's underlying genetic causes as well as possible ways to treat it. The company has signed on Baylor College of Medicine, Yale School of Medicine and the Broad Institute as its first customers.
