Almost 25 years after the Human Genome Project launched, and a little over a decade after it reached its goal of reading all three billion base pairs in human DNA, genome sequencing for the masses is finally arriving. It will no longer be just a research tool; reading all of your DNA (rather than looking at just certain genes) will soon be cheap enough to be used regularly for pinpointing medical problems and identifying treatments. This will be an enormous business, and one company dominates it: Illumina. The San Diego–based company sells everything from sequencing machines that identify each nucleotide in DNA to software and services that analyze the data. In the coming age of genomic medicine, Illumina is poised to be what Intel was to the PC era—the dominant supplier of the fundamental technology.
