The Year in Biotech

Genomics Gets Really Personal
This year may be remembered as the turning point for personal genomics, when broad gene testing for individuals finally came within reach. Two genomic pioneers?James Watson, codiscover of the structure of DNA, and Craig Venter, leader of the private effort to sequence the genome?published the sequence of their own genomes, revealing personal disease risks. (See “The $2 Million Genome” and “Craig Venter’s Genome.”)

Taking advantage of the explosion in human genomics data, several companies launched direct-to-consumer gene-testing services that analyze an individual’s genetic risk of contacting a range of diseases, including Alzheimer’s, diabetes, and cancer. (See “Your Future, on a Chip” and “Your Personal Genome.”) Critics say it’s not yet clear how useful such tests will be in preventing disease. So with price tags ranging from about $1,000, for a microarray analysis that analyzes a million genetic variations, to $350,000, for a full genome sequence, it might be worth waiting.
