Human Health

Overview

“De novo” sequencing, or constructing an individual’s genome from his or her own data alone (as opposed to comparing it to a reference genome), is a formidable task, akin to assembling a jigsaw puzzle comprising hundreds of millions of small blank pieces. Drs. Si Lok, Stephen Scherer, and their colleagues from The Hospital for Sick Children are developing a new “mate-pair” technology that would overcome the financial and logistical barriers to de novo sequencing by linking sequences to one or more other reads in precisely known orientations and distances. Mate-pair technology would create a high-resolution backbone to enable de novo sequencing to be carried out in a single simple step. This new adaptation of mate-pair sequencing is a disruptive technology that could supersede all current methods of de novo sequencing, thereby representing a leap forward in many areas of research and, ultimately, in healthcare.
