Helix's sequencing technology is called Exome+. The “exome” is comprised of all the DNA that encodes for protein—and because proteins are the machinery of your cells, the exome represents some of the most important and well-studied pieces of your DNA. But the exome is only part of your DNA story. The genetic experts at Helix have identified other important information-rich areas to sequence (hence, Exome+). 

Why not whole-genome?
The remainder of your DNA, which would comprise a full genome sequence, is currently regarded as either uninteresting or not useful for any real application, according to current scientific consensus. That may change in the future, but for now, we've decided to use Exome+ to provide the most service to you at the lowest cost.
