The human genome contains approximately 20,000 genes, and exome analysis focuses on about 7,000 genes known in medical literature to be clinically associated with a disease. Currently, up to 70 percent of exome test reports are negative or inconclusive. But suppose at a later date a researcher discovers a gene that could be causative of the disease?
It's been nearly a decade since scientists completed the Human Genome Project - a scientific marvel that, in its essence, provided the blueprint for the genetic make-up of humans.
