Whole genome sequencing 'not ready for widespread clinical use'

Both the technical barriers associated with human DNA sequencing and the costs involved have been decreasing for some time. A new study investigates the benefits and drawbacks of whole genome sequencing in clinical applications.The first sequencing of a human genome began in 1990 and was completed in 2003 at a cost of $2.7 billion. Now, whole genome sequencing (WGS) can cost as little as $1,000, with the procedure taking just days.When sequencing an organism's DNA, the order of DNA nucleotides is documented by machines.
