Exome+ is Helix' proprietary approach sequencing technology . 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 (that’s the “plus” in Exome+).
